1.3 Typical Configurations of the MA5100 Cabinet

The MA5100 can be powered in three modes: 110V/220V AC and -48V DC. GEPS 4845 is used as AC power supply, while power distribution box as DC power supply. Both of them are maintained from the front. See Chapter 7 Appendix for cable connection inside the cabinet.

Based on the ADSL board types, the MA5100 has two cabinet configurations: configuration with a SPL frame and configuration with no SPL frame.

1.3.1 Configuration with SPL Frame

When the ADLD/ADLI board is adopted, the splitter board (SPLC/SPLI) is required. The SPLC/SPLI board is a passive board plugged to the SPL frame.

Refer to 05-Chapter 5 Arrangement of Cables and Optical Fibers for the cable connection between the ADL board and the SPL board.

2.2.3 Floor Loading Considerations

The load bearing capability of the equipment room should be larger than 450kg/m2 (When the battery is configured in the cabinet). Considering the heavy weight of the lead acid battery, when the battery below 500AH is mounted in the battery room, the load bearing of the battery room should be larger than 500kg/m2. When the battery over 800AH is to be mounted, the load bearing should be larger than 600kg/m2. The load bearing standard of the aisle and stairs is 400kg/m2 (without battery). The overload coefficient is 1.4. The load bearing capability for places outside the equipment room is not less than 300kg/m2. For an old building, the bearing capability should be much higher.

2.2.4 Power Supply Requirements

In addition to the mains input, the optional backup power supply is available. The DC power distribution equipment meets the requirements of the system. The

output power voltage is stable and is within the rated range. The battery backup is available. It can ensure the system normal operation in case

of power supply failure. The AC power supply system has an independent ground wiring.

2.2.5 Peripherals

If there is transmission equipment, it should be pre-installed before mounting the MA5100. Make sure the optical transceiver is in place, the optical fibers are laid properly, the pigtails of the optical fiber have been labeled, and the cabling rack and main distribution frame are configured well.


2-4

2.2.6 Grounding Requirements

A correctly installed electrical system helps ensure personnel safety and reliable performance. The system must be correctly grounded before you connect power or mounting the equipment.

2.2.7 Other Facilities

In the equipment room for network management, facilities such as computer desks, chairs, power sockets, and a telephone are necessities.

Chapter 3 Equipment Installation

H66-18 cabinet and H66-22 cabinet can be installed on cement floor, or on raised floor. Expansion bolts are used for fastening to the cement floor, and S600A series brackets are used for mounting on the raised floor. These two installation modes are similar ,so we use H66 to stand for both of them in the following sections.

Caution:

The H66 front-access cabinet has no feet with it and is fixed with expansion bolts. 8U-high (1U = 44.45mm) space is required for its installation. If there is not sufficient height left, dismantle some modules in the lower part of the cabinet first.

Insulating plate is put under the cabinet on the ground, and insulating shell around the expansion bolts. Make sure that the insulating units are correctly installed so that the whole set of equipment is insulated from the ground before the ground wire is connected, thus effectively meeting the insulation requirement.

3.1 Cabinet Installation on the Cement Ground

The H66 cabinet is fixed to the cement ground with expansion bolts.

Precautions in installation:

The site should be correctly marked off prior to the installation. Otherwise, the installation work may have to be done again.

The cabinet must be conveyed with care to prevent damage to any components. Make an overall inspection of the cabinet after the installation is completed. Solve

in time any problems that have been found, and clean the stains resulting from the installation.

3.1.2 Cabinet Positioning

I. Planning the installation position of cabinet

Before the installation, first plan the available space. There should be sufficient space for maintenance and operation at the front doors of the cabinet when it is installed against the wall, as shown in Figure 3-2 and Figure 3-3. Figure 3-4 illustrates the back-to-back installation of two cabinets.

II. Drawing lines

According to the reference dimension in the construction plane design diagram, determine the location of the cabinet installation hole, measure several marking-out points, mark out two lines which are parallel with the reference and whose spacing is 460mm. According to the design requirements, determine the installation hole location for the first cabinet on the two lines. Then take the hole as the reference point, and mark out the installation holes for other cabinets one by one. To avoid faults, after being marked out, all hole location lines should be measured again so as to ensure the proper dimension. Figure 3-2 shows installation hole location for single cabinet installation; Figure 3-3 shows that for side-by-side installation; Figure 3-4 shows that for back-to-back installation.

Note:

Make sure the marking-off plate is installed in right direction.

III. Drilling holes

Use a percussion drill with Φ16 bit to drill holes for the installation of the expansion bolts.

When using the percussion drill, be sure to hold the bit perpendicular to the ground. Hold the drill handle firmly with both hands to control the direction. Do not shake the drill to avoid tilted holes or prevent damage to the floor.

The depth of the hole should be within the range of 52mm~60mm, and the depth of all holes should be the same. Clean the hole before measuring the net-depth. When a hole is drilled, use a vacuum cleaner to clean the dust.

If it is difficult to position the drill bit when the ground is too hard or slippery, chisel a pit at the hole-mark to help position the bit.

Marking and drilling are the fundamental work for hardware installation. Any poor precision may cause great inconvenience for the follow-up jobs.

Caution:

Keep the depth of the hole between 52mm and 60mm. Otherwise, the expansion bolt cannot be installed and fastened properly.

IV. Installing expansion bolts

Prior to installation, clean the dust inside and outside the hole with vacuum cleaner and then measure the spacing between holes. Relocate and drill before installing expansion bolt in case of poor accuracy.

Installation procedures:

Insert the guide rib on the expansion nut into the guide trough of the expansion tube in advance. It is required for installation and fastening of expansion bolts.

Take down the expansion tube and expansion nut, put them into the hole vertically.

3.3 Installing the Cabling Rack

When up-wiring is adopted, the cabling rack needs to be installed. Various types of the cables in the equipment room can be laid upon the cabling rack. Also, the installation of the cabling rack can reinforce the equipment and enhance the shockproof performance of the equipment. Regarding the specific location of the cabling rack in the equipment room, the cabling rack can be installed in four ways. Note that the cabling rack must be insulated from the ground surface, the roof or the wall.

Install a suspender on the ceiling to hang the cabling rack (hereinafter referred to as the ceiling-mount installation mode)

Install a bracket on the ground to support the cabling rack (hereinafter referred to as the ground-supporting installation mode)

When the cabling rack runs over the cabinet, install a shock-proof support or a ladder on the cabinet to support it

When the cabling rack is spanned against the wall, a triangular support can be installed on the wall to support it

The cabling rack is mainly present in the form of the cabling ladder. Wiring trough is also optional. The specifications are listed below:

1) 200mm-wide cabling ladder matches 200mm-wide wiring trough 2) 400mm-wide cabling ladder matches 400mm-wide wiring trough 3) 600mm-wide cabling ladder matches 400mm+200mm-wide wiring trough

It is recommended to adopt the 400mm-wide cabling ladder over the cabinet and no wiring trough is opted so as to facilitate the wiring and the heat-dissipation of the system.

I. Structure and Assembly of the Cabling Ladder

The cabling ladder adopts the U-steel and the crosspiece as its framework, in which the U-steel acts as the vertical post of the cabling ladder and the crosspiece functions as the horizontal beam. During the assembly, just use the fastener to connect the crosspiece with the U-steel. The spacing between two crosspieces is 250mm. Since the hole spacing of the U-steel is 50mm, one crosspiece should be installed every 6 trough holes. When the assembled cabling ladder is used for the horizontal installation of the cabling rack in the equipment room, the bolt head of the cabling ladder should face downward, so as to facilitate the installation of the wiring trough since there is no protruding on the cabling ladder. The basic structure of the cabling ladder is as shown in Figure 3-32.


3-30

(1) U-steel (2) Fastener (3) Crosspiece

Figure 3-32 Structure of cabling ladder

When the project requires a long cabling ladder, multiple segments of cabling ladder can be joined end to end. The connecting part is the U-shaped connecting piece, as shown in Figure 3-33. When the length of the cabling ladder is not the integral multiple of 2.5m in the actual installation, cut out the remainder. Paint the cross-section to ensure rust resistance and a neat outlook.

(1) U-steel (2) U-shaped connecting piece (3) Fastener (4) Cabling ladder B

Figure 3-33 Connection of cabling ladders

II. Connecting and Installing the Wiring Trough

Since the wiring trough is conical to some degree, just insert the smaller end of the wiring trough to the bigger end of another to connect them. The length of the inserted part is 250mm.

When the 200mm-wide or 400mm-wide wiring trough is opted for the project, directly place it on the cabling ladder. Then, secure the wiring trough on the cabling ladder with the wiring trough fixing clip. Four clips are used for each segment of the wiring trough,


3-31

which should be symmetrical at the both sides. Figure 3-34 shows the inter-trough connection and installation.

Figure 3-34 Inter-trough (200mm-wide or 400mm-wide) connection and installation

When a wiring trough is opted for the 600-millimeter-wide cabling ladder, it can be the combination of a 400mm-wide trough plus a 200mm-wide trough, which are joined by connecting clips. For each segment of wiring trough, three connecting clips are used. Secure the wiring trough onto the cabling ladder with the fixing clips. When the wiring trough needs to be lengthened, the connecting method is the same as that mentioned previously. Note that the trough should be lengthened first, and fixed next. The specific connection is as shown in Figure 3-35.

III. Bending the cabling rack

1) Bending on a horizontal surface

When the cabling rack needs to be bent at a right angle on a horizontal surface, there are two different installation methods depending on whether the wiring trough is opted for the cabling rack.

No wiring trough opted


3-32

When the intersecting cabling rack is solely composed of cabling ladders, use mount angles and fasteners to join the two cabling ladders together. Make sure that the two cabling ladders are at the same surface. See Figure 3-36.

(1) Cabling ladder A (2) Cabling ladder B (3) Mount angle (4) Fastener

Figure 3-36 Cabling ladder bending on horizontal surface

Wiring trough opted

If any of the intersecting cabling racks has a wiring trough, the spacing of the two cabling racks should be equal to the height of a wiring trough. That is, the height of the cabling ladder for one party should be at the same level with the cabling trough of the other, so as to ensure the cable run smoothly on the cabling rack. The installation is shown in Figure 3-37. Mount angles and fasteners are also used here for the connection, but the installation method of the mount angle is different from that illustrated in Figure 3-36.

(1) Wiring trough (2) Cabling ladder A (3) Cabling ladder B (4) Mount angle (5) Fastener

Figure 3-37 Bending of a cabling rack configured with wiring troughs on a horizontal surface


3-33

2) Joining the cabling racks

When the cabling ladder is to descend or ascend, make a climbing ladder of the following type using mount angles and the fasteners. Figure 3-38 shows the perpendicular joining of the cabling ladder, in which the left figure is the illustration of the joining at the front side and the right figure is the joining at the side. Pay attention to the installation methods of the mount angles. Figure 3-39 shows the oblique joining.

IV. Attaching the cabling ladder to the wall

When the cabling ladder has to be attached to the wall, perform the installation according to Figure 3-40. The connecting parts include mount angles, insulating plates, insulating washers, fasteners and expansion bolts. Insulating plates and insulating


3-34

washers are used to insulate the cabling rack from the wall. Replace the washer contained in the expansion bolt with the big flat washer Ø8, so as to increase the contacting area of the washer and the insulating washer.

Figure 3-40 Attaching the cabling ladder to the wall

V. Ceiling-mount or floor-mount installation

When the cabling rack is not attached to the wall, the ceiling-mount or floor-mount installation method can be adopted. In the former method, the cabling rack is connected to the ceiling; in the latter case, the cabling rack is connected to the ground. U-steel, mount angles, fasteners and the expansion bolts are used for the connection . Two pieces of U-steel are used to connect the cabling ladder to the wall or the ground. The installation is the same as connecting a cabling rack to the wall.

Each piece of U-steel is 2.5m. Depending on the height of the cabling rack and that of the equipment room, the steel can be cut to a suitable length. When the required length is longer than 2.5m, you can join two pieces of U-steel together. The connecting method is the same as that of cabling ladder connection. The U-shaped connecting piece is used for the connection. Remember paint the cross-section.

Since the hole spacing of the U-steel is 50mm, the spacing of the suspender or the pole support should be the integral multiple of 50mm. Otherwise, it is impossible to proceed with the installation. It is recommended that the spacing of the two sets of the suspending link or supporting link be 1250mm, i.e., each segment of the cabling ladder be borne by two sets of suspender or pole support.


3-35

In ceiling-mount installation or floor-mount installation, the suspender or the pole support has to be installed at the outer side of the cabling ladders to facilitate positioning of the wiring trough. Ensure the insulation between the suspender/pole support and the ceiling/ground. Make sure to add the insulating plate and the insulating washer, as shown in Figure 3-41.

VI. Installing the triangular support

When the cabling rack is installed against the wall, triangular supports are used.

The triangular support adopts the welded structure, and is fixed on the wall via expansion bolts. On its horizontal beam, there are some holes for installing cabling ladder. Three types of triangular supports are available, corresponding respectively to installation of the 200mm-wide, 400mm-wide, and 600mm-wide cabling ladder (the triangular support with greater length can be used to support the smaller cabling ladder, but it is not recommended).

When installing the cabling ladder, place the cabling ladder upon the horizontal beam of the triangular support, and then tighten them with connecting pieces.


3-36

Caution:

The distance between two triangular supports must be an integer multiple of 50 mm. Otherwise, the cabling ladder cannot be fixed with triangular supports. The recommended distance is 1250mm, that is, each segment of cabling ladder is supported by two triangular supports.

Here, replace the flat washer contained in the expansion bolt with the big flat washer Ø8. Two pieces of insulating plates must be installed between the vertical post of the triangular support and the wall, and installation pads must be installed between the nut and the vertical post. Be sure that each nut is outfitted with an insulating washer. Figure 3-42 shows the installation method of the triangular support.

Figure 3-42 Installation of triangular support

VII. Connection at cabinet top

When the cabling rack runs over the cabinet top, the cabinet-top connection mode is adopted. To improve the heat dissipation of the system, usually, the wiring trough is not opted for the cabling rack at the cabinet-top. There are two methods for the cabinet-top connection.

1) Cabinet-top shockproof support connection

The cabinet-top shockproof support is welded angle iron, ensuring the intensity. Two bolt holes at the cabinet top are used to secure the shockproof support. The shockproof support is used to bear and fix the cabling rack. Fasteners are used to fix the ladder to the shockproof support via the bolt holes on the shockproof. See Figure 3-43 and Figure 3-44 for the connection.

2) Connecting the climbing ladder

When there is no support on the cabinet top, connect a climbing ladder according to the size of the holes on the cabinet top. Please refer to the right diagram in Figure 3-38 and Figure 3-39.

VIII. Installing accessories

1) Installing the cable-through rack

There are two installation methods for the cable-through rack, depending on whether the wiring trough is opted. Figure 3-45 illustrates the case when the wiring trough is not opted for the cabling rack. Here, the hole at the upper row of the cable-through rack is used. When the wiring trough is opted, the hole at the lower row of the cable-through rack is used, ensuring that the upper plane of the cable-through rack is kept about the


3-38

same level with the top plane of the cabling rack. This is for the convenience of cabling. Generally, the cable-through rack is installed on the cabling ladder of the cabinet top. Its quantity and location varies with the actual condition.

(1) Cabling rack (2) Cable-through rack (3) Upper-row hole of cable-through rack (4) Lower-row hole of cable-through rack

Figure 3-45 Installation of cable-through rack when no wiring trough opted for cabling rack

2) Installing side shield, cable-shielding rings and cable bushing

The cable-shielding rings are directly clipped at both sides of the wiring trough. By adding the cable-shielding ring, the edge of the wiring trough is heightened and the cable could not easily get across the wiring trough. See Figure 3-34 for illustration. Four cable-shielding rings are used for each segment of wiring trough and they are located evenly at both sides.

Side shield is installed at the side of the cabling ladder. This is to keep a good outlook and avoid unintentional damage to the cable.

The cable bushing is installed at the bottom edge to avoid any possible damage to the cable. Any naked bottom edge of the wiring trough should be installed with cable bushing. Please refer to the left diagram in Figure 3-38 for the installation of the side shield and the cable bushing.

3.3.3 Shockproof and reinforcement measures for the cabling rack

As shown in Figure 3-46, cabling racks have formed a network and are connected with the cabinet as an integrated body, which accommodates excellent shockproof functionality. Therefore, when planning the shockproof and reinforcement for the cabinet, just connect the cabling rack to the wall with the U-steel where it is necessary to enhance the shockproof performance of the whole network (including the cabinet). It is recommended to install a piece of U-steel at every other cabinet. The connecting method to the wall is the same as that for ceiling-mount or floor-mount installation,


3-39

where mount-angles are also used. Ensure the insulation between the whole network and the wall by adding insulating plate and insulating washer.

Figure 3-46 Installation of cabling rack and shockproof reinforcement of cabinet

Note:

Always wear ESD-preventative strap when mounting or removing a board. When inserting a board into a slot, push it in slowly. To install a board, place the board properly in the guide rails, so that it can be contacted with the

backplane properly. Fasten the two captive screws in the front panel, so as to ensure reliable contact between the front

panel and the frame.

3.7 Cleansing and Installing the Air Filter

I. Removal and Installation of the air filter

Both the front and bottom of the H66 cabinet are equipped with air filters.


3-44

The air filter on the front door is made of sponge, making it easy for the filter removal and installation. However, due care should be taken to prevent the filter from any damage.

The filamentary filter at the cabinet bottom does not have a baffle. With its resilient elasticity, this filter can be forcefully inserted into the Z-shape dampers on the sides (as illustrated in Figure 3-51). To remove it, just draw it out from the Z-shape dampers slowly.

Figure 3-51 Installation of the air filter

II. Cleasing of the air filter

To guarantee proper heat dissipation and system ventilation, it is necessary to cleanse the air filter regularly, e.g., every 3~6 months as recommended.

Usually, when installed in a well-conditioned equipment room, the air filter is to be cleaned every 6 months; and when installed in a poor-conditioned room, the air filter is to be cleaned every 3 months.

There are two cleansing methods for the air filter: dry-cleaning and water-washing.

1) Dry-cleaning

Remove the air filter from the cabinet. Flap off the thick dust off the filter, and then use a vacuum cleaner to remove the remaining dust on the filter. Finally reinstall it to the cabinet. Dry-cleaning is suitable for sponge filter.

2) Water-washing

Remove the air filter the cabinet. Flap off the thick dust off the filter, and then use a water pipe to wash it (the maximum water pressure is 20KPa, and the maximum water spray height is 1.5m). Finally reinstall the air filter to the cabinet after it becomes dry. Water washing is suitable for both filamentary and aluminum dust-proof screens.


3-45

Note:

You can choose to adopt either dry-cleaning or water-washing as desired. Water-washing can better clean the air filter. However it takes time since you can reinstall it after it becomes dry.

4-1

Chapter 4 Installing Power Supply System

4.1 Overview

The MA5100 uses a distributed power supply system. The working power of each board is supplied by the DC/DC module, and the system is powered with -48V DC input power. The MA5100 cabinet supports power supplies of either 220V AC, 110V AC or -48V DC.

In 220VAC power supply, GEPS4845 (220V) power module and SPD23SZ lightning protection box are used.

In 110VAC power supply, GEPS4845 (110V) power module and SPD32SZ lightning protection box are used.

In -48VDC power supply, power distribution box is used.

4.2 Installing AC Power Supply System and Corollary Equipment

4.2.1 Installing Lightning Protection Box

I. Overview of SPD23SZ Lightning Protection Box

The MA5100 uses the SPD23SZ lightning protection box (referred to as SPD23SZ hereinafter). This lightning protection box is designed to be installed in a 19-inch cabinet. In compliance with the requirements specified in IEC-60664, IEC-61312 and IEC-61643, it provides Class C protection for single-phase AC power supply. It provides efficient protection against over-voltage and alarm circuit.

1) Introduction to lightning protection box

Dimensions of the SPD23SZ are 276.0×270.0×137.2mm (H×W×D). It weighs 4.26kg. There are three cabling holes (I~III) at its top, and two holes at the back for securing purpose. Front view and rear view of the SPD23SZ are shown in Figure 4-1 respectively.


4-2

(1) RUN (in green) (2) ALM (in red) (3) ON/OFF switch

Figure 4-1 Front view and rear view of the SPD23SZ

2) Over-voltage protection

When the voltage of mains reaches 295V~305V, the over-voltage protection function of the SPD23SZ will be started. It cuts off the power supply to the MA5100 to protect the power supply system and equipment. When the mains voltage falls to 280V~290V or even lower, the power supply to the MA5100 is recovered.

Note:

When the over-voltage protection function is started, the SPD23SZ still provides the lightning protection function. The green LED on its front panel remains on.

3) Application range

Due to the capacity limit of the over-voltage protection circuit, the SPD23SZ is mainly used for the power system with AC input less than 20A.

II. Introduction to SPD32SZ lightning protection box

When the MA5100 is power by 110VAC supply, SPD32SZ lightning protection box is required, to protect the power module and loads from being surged by lightning over-voltage or transient over-voltage.

Characteristics of SPD32SZ lightning protection box:

Series circuit can ensure high protective performance and low residual voltage. Temperature on/off control and built-in overvoltage circuit can prevent totally fire

disaster. Multiple auto current balancing makes it a preference for the area often stricken by

thunder. Common mode and differential mode protection Mains-diesel alternative switch

2) The cross sectional area of the phase lines (L) and neutral lines (N) through the SPD23SZ should not be smaller than 6mm2. It is recommended to use copper-pin cables.

3) Use copper-pin cables not smaller than 25mm2 as the ground cable. 4) Resistance of the grounding devices should be smaller than 5Ω.

IV. Installing lightning protection box


4-4

Note:

Shut off the power supply before installing the SPD23SZ. Make sure that no dangerous voltage exists on the neutral line (N).

After the LPB installation is completed, turn on the MCB to start the LPB. If the MCB is switched off, then the lightning protection function will become unavailable and the power supply will be terminated. Therefore, it is forbidden to switch off the MCB in the LPB during normal operation.

1) Secure the SPD23SZ against the wall using two expansion bolts. The AC power cord between the SPD23SZ and the MA5100 should be 5~10m.

2) Open the faceplate of the SPD23SZ, and perform the cabling according to the joint detail attached on the back of the front panel.

3) Led out a ground cable (PE line) from the grounding busbar in the SPD23SZ, and then connect it to the protection grounding bar in the equipment room. The cross sectional area of the ground cable should not be smaller than 25mm2. Keep the connection cable as short as possible. The grounding resistance should not be larger than 5Ω.

4) Make sure that all connections are reliable and proper. 5) Make sure that all the connections conform to the joint detail. Then connect the

power at the miniature circuit breaker (MCB) to power on the SPD23SZ. Confirm that the RUN LED on the panel lights, and the ALM LED lights when the power at the MCB is disconnected.

6) Close the cabinet faceplate.

Note:

MA5100 grounding must be connected to the grounding bar of the lightning protection box. For the electronic connection of the LPB and MA5100, see 4.2.2 Figure 4-4.

V. Maintenance of the Lightning Protection Box

1) If the green LED on the panel lights, it indicates that the lightning protection function is normal.

2) If the red LED on the panel lights, it indicates the lightning protection box failure. In such case, contact the customer service personnel of Huawei Technologies in time for SPD23SZ replacement.

3) If it is required to disconnect the PE line for some reason, cut off the AC power supply to the SPD23SZ first to remove the dangerous internal voltage. Always confirm there is no dangerous voltage in the neutral line (N).

4) The prerequisite conditions for normal operations of the SPD23SZ are as follows:


4-5

Ambient temperature: -40°C~40°C Altitude: ≤3000m. Power frequency: 48~62Hz Wind speed: ≤35m/s

Note:

The LPB is designed to be used in normal conditions and adverse environment as well. However, part of its performances may deteriorate unexpectedly when working in adverse conditions. It is recommended to make routine inspection of the LPB, and fix problems or faults in time.

4.2.2 Installing Primary Power Module

Remove transparent protective cover on the panel, and take out the baffles above AC terminals along the direction of arrow. The OT-4 terminal can be used as AC terminals. You can decide load terminal model and load cable model accordingly.

Make power cable on site by yourself as per the following steps:

1) Cut a piece of cable of proper length based on the site need. 2) Strip cable sheath and put on heat-shrink tube. 3) Crimp OT terminal to the cable with crimp pliers. 4) Heat the heat-shrink tube up to stick it fast to the cable.


4-8

Caution:

Make sure AC input is cut off during cable connection, since it is live with high voltage otherwise. Temporary label is required for the switch which is prohibited to move in cable connection.

Fully insulate connection points of AC terminals and other bare points which are not required. Cover the baffle again over the terminal after cable connection.

IV. Installation procedure:

As shown in Figure 4-4, connect the blue live line led out from the lightning protection box to the AC-L terminal of the GEPS4845 power module, and the black neutral line to the AC-N terminal. The line should be 5~10m long. Choose U-type terminal as AC terminals. You can decide load terminal and cable model accordingly.

Connect one end of the yellow-green PGND line (from the lightning protection box to MA5100) to the terminal, and the other end to ground bar at the lightning protection box. Tighten the fastening nuts at both ends. The cross-sectional area of the ground wire must not be less than 25mm2 and the length less than 10m.

It is needed to lead out a protection ground cable from the lightning protection box, as shown in Figure 4-4. Connect the other end to protection ground bar of the equipment room. The cross-sectional area of the ground wire must not be less than 25mm2. Its length should be as short as possible. The grounding resistance value of the protection grounding bus in the equipment room should not be larger than 5Ω.

4.2.3 Installing the Battery

Batteries are not pre-installed in the cabinet due its heavy weight. The arrangement and cablings of batteries are implemented on site. To install the batteries, follow exactly the descriptions below. Any short circuit may hurt personnel and damage the equipment.

Note:

In most cases, four batteries which forms a group can meet the power supply requirement. You can install two groups of batteries when necessary.

I. Introduction to battery rack

As the batteries are installed outside of the MA5100, the external battery racks are needed.


4-12

The battery rack consists of rack, cover, cable fixing socket and cabling stud. The cabling stud is protected by the cover. See Figure 4-6 for the mechanical outline of the battery rack.

(1) Rack (2) Wire fixing base r

Figure 4-6 Mechanical outline of battery rack

II. Installing the battery rack

The load-bearing capacity of the floor in the equipment room is required to be at least 500 kg/m2 for the installation of the battery rack.

Tools required for installing the battery rack include:

One cross screwdriver One flathead screwdriver Two wrenches One angle plier One multimeter

III. Battery installation precautions

When a battery is in the open-circuit state, its performance will degrade irreversibly. Long time storage of batteries (more than three months) without recharge will cause an irrecoverable loss of battery capacity, which affects the battery’s service life severely.

Before the installation, measure the open circuit voltage of the battery. If the open circuit voltage is lower than the specified lower limit (12.48V for 12V battery, and 2.08V for 2V battery) due to self-discharge, or the batteries are not installed three


4-13

months after arrival, the battery must be recharged. The charge mode is the forced even charge. The charging voltage is 14.3~14.5V/PC (for 12V battery), or 2.35~2 .45V/PC (for 2V battery), and the charging time is 20~24 hours (do not exceed 24 hours).

If the open circuit voltage of the battery is too lower (12.12V for 12V battery, and 2.02V for 2V battery) due to self-discharge, ask the specialists to handle it.

During the installation, each battery should be kept at least 10mm space away from each other, facilitating its heat dissipation during the running.

Caution:

1) The batteries must be connected with the power supply system correctly. Otherwise, they may not be managed properly, or the recharge current may be too excessive. Therefore, it is necessary to check the wiring connection carefully. If any problem arises, resolve it immediately. 2) Disconnect the power distribution control equipment before installing battery. 3) Operate the equipment carefully, and avoid reverse connection or short circuit.

IV. Installing batteries

Install the battery according to the following procedure:

1) Put the battery on the battery shelf

The battery support has two layers and each can accommodate four batteries. shows the installation effect of the batteries on the shelf. ith one battery group installed only, the batteries should be installed at the lower layer.

2) Connect the anode and cathode of each group of batteries

Figure 4-8 (1-3) shows the connection of one battery group, and Figure 4-9 (1-6) shows that of two battery groups.

3) Connect the battery to the power frame in the subscriber cabinet

Figure 4-8 (1) and (2) show the connection of one battery group, and Figure 4-9 (1)-(4) show that of two battery groups.

4) Bundle all cables to finish the installation.

V. Checking the battery installation

After the battery shelf is installed, follow the steps below to check if the battery can work normally.

1) Connect correctly the battery and the GEPS4845 power supply. Turn on the AC power supply and check if the system is normally powered (the board LEDs are in normal status).

2) Turn off the AC power input and check the board LED status. If the LED status is still normal, it means that the battery works normally. If the LED turns off, it means that the battery does not work normally. In this case, find out the problem and reinstall the battery.

VI. Precautions

1) When a battery is in the open circuit status, its performance always degrades irreversibly. If the batteries have not been recharged during long storage (more than 3 months), an irrecoverable loss of battery capacity will occur, which will severely affect the batteries’ service life.

2) If the open circuit voltage is lower than the specified lower limit (12.48V for 12V battery, and 2.08V for 2V battery) due to self-discharge, or the batteries are not installed three months after arrival, then you must charge the batteries. The


4-16

charging mode is the forced even charging. The charging voltage is 14.3~14.5V/PCS (for 12V battery), or 2.35~2 .45V/PCS (for 2V battery). The charging time is 20~24 hours, but should not exceed 24 hours.

3) Recovery of stable voltage recharge: If the open circuit voltage is below the specified lower limit (12.12V for 12V batteries, 2.02V for 2V batteries) due to self-discharge of the battery, only professionals are entitled to handle the situation.

4) Please measure the open circuit voltage of the batteries before installation. The voltage of the 12V battery should not be lower than 12.48V and that of the 2V battery should not be lower than 2.08V. Otherwise, the batteries need to be charged.

Caution:

The connections between the batteries and the power distribution system should be proper, or it will cause problems such as: The battery management cannot be implemented, excessive battery charging current, etc. Therefore, please check whether the system connections are proper and modify in time if any problem is found.

4.4 Installing DC Power Distribution Box

4.4.1 Installing Power Distribution Frame

I. Introduction to power distribuition frame

To extend electric interfaces and facilitate cable distribution, connect the -48V power supply directly to the power distribution frame, and then to transmission equipment and the MA5100 through the power distribution frame and cables.

Figure 4-11 shows the outline of the power distribution frame.

(1) Output terminal (2) Output switch (3) Input terminal (4) Monitoring parameter output terminal (5) Surge protection board

Figure 4-11 Outline of power distribution frame

Components and their functions:

The output terminals are common UK6N terminals. They are 18 terminals forming 9 load outputs (One output comprises one pair of positive pole and negative pole).

The three independent branch switches controls the nine load outputs respectively. The branch switch uses magnetic-break protector. The rated current of each switch is 50A. When there is occurrence of short-circuit or over-current, the switch will be automatically broken to isolate the failure.

The input terminals are OT terminals. They are used for reliable connection of power cables. The terminals have transparent attachable protection caps, which ensure efficient separation from other components and objects.

The monitoring parameter output terminal is a DB15 connector. It supports outputting four digital signals including the signal of DC input surge protection and the signals of branch switch status, which monitor whether the surge protection circuit is valid and whether the three branch switches are normal respectively.

The surge protection board suppresses transient surge current of external -48V DC input. When its protection circuit becomes invalid, the board can be pulled out or plugged in at hot-line situation for maintenance.


4-19

II. Installing power distribution frame

There is one mount ear at both sides of the DC power distribution frame, and each mount ear has two bolt holes used to fasten the screws.

Installation process

1) Install captive nuts to the mount angles of the cabinet according to the frame position.

2) Put the power distribution frame on the corresponding slide rail in the cabinet, and then push it into the cabinet gently, making its mount ear contact mount angle of the cabinet.

3) Adjust the power distribution frame, making it in the middle of the cabinet. Here, the four bolt holes on the mount ears at both sides of the power distribution frame should be aligned with the captive nuts on the mount angles of the cabinet, and then screw in four panel fasteners M6%12 to secure the power distribution frame.

4) Install the delivery attached protection cover of the power distribution frame.

Caution:

When fastening screws, screw them lightly, and then tighten them diagonally.

4.4.2 Connecting Cables

I. External electric connection of power distribution frame

The power cables of the power distribution frame are connected through the terminal blocks on the front panel of the system. The electric connection includes -48V leadin connection and load leadout connection.

1) Connecting -48V DC leadin

Connect two (or one) -48V power supply inputs of the equipment room directly to the terminal block in the middle of the power distribution frame, as shown in Figure 4-11. Here, “NEG(-)”, “RTN(+)”, “PGND” are connected to the external -48V cable (blue), RTN cable (black) and PGND cable (yellow green) of the equipment room respectively.


4-20

Caution:

If the equipment room has only one -48V power supply input, the wiring terminals “NEG(-)” and “NEG(2)” on the terminal block of the power distribution frame must be connected.

2) Connecting load leadout

The branch switch SW1 can be connected with three channels of load leadout, which are connecting to the three 1- and 1+ terminal pairs respectively. The 1- terminal connects to the -48V (negative pole) of the power supply and the 1+ terminal connects to the BGND (positive pole) of the power supply.

The branch switch SW2 can also be connected with three channels of load leadout, which are connecting to the three 2- and 2+ terminal pairs respectively. The connection mode is similar to that of SW1.

The branch switch SW3 can be connected with two channels of load leadout, which are connecting to the two 3- and 3+ terminal pairs respectively.

The ESC (-) and ESC (+) terminals correspond to environment monitoring frame. It is an independent branch load.

II. Installing Power Cord and Grounding Cable for cabinet

If the cabinet uses –48V DC power supply, it does not require the AC/DC power frame. The –48V power cords are directly connected to the power distribution frame (PDF) at the uppermost part of the cabinet. The cables are led in from the top of the cabinet. Figure 4-13 shows the connection of the external power cord and the grounding cable.

If there is no DC power distribution cabinet (or the power distribution box) in the equipment room, connect the BGND cable to the 48V positive pole bar of the DC power cabinet. The sectional area of the connecting cable should not be less than 16mm2 and the keep the connecting the cable as short as possible.

PGND cable connect one end of the protection grounding cable (in yellow-green) to the “PGND” terminal inside the MA5100 cabinet, and the other end to the PGND grounding bar of the DC power distribution cabinet (or the PDB). If the DC power distribution cabinet (or the PDB) is unavailable, connect the protection grounding cable to the


4-22

protection grounding bar of the equipment room. The sectional area of the connecting cable should not be less than 25mm2, and the connecting cable should be as short as possible during the engineering construction.

4.5 Installing Power Cords and Grounding Cables for Combined Cabinets

Combined cabinet installation mode may be required to keep same potential between the basic cabinet and extension cabinet when local subtending is used for adding new subscribers. Then the combined cabinets can only be powered by external DC power unit for convenience of centralized monitoring and management.

In this installation mode, the grounding bars of two MA5100 cabinets are shorted with wires of 6mm2 sectional area and 300mm length. Figure 4-14 shows the position of these shorting wires.

Chapter 5 Arrangement of Cables and Optical Fibers

5.1 Cabling Requirements

The technical requirements and precautions during cabling work are as follows:

1) The power cables, ground wires and various signal wires should be firmly and reliably connected at both ends, and the socket connections or screw connections should be reliable. If two or more OT terminals are to be installed on one connector post, the cross installation mode should be adopted. The smaller OT terminal(s) should be installed above the larger one(s), or the OT terminal should be bent by 45° or 90°. The overlapping installation is not allowed for the OT terminal.

(1) The overlapping is forbidden (2) Bent by 45°or 90° (3) It is forbidden to install the smaller terminal below (4) Cross installation

Figure 5-1 OT terminal installation

2) Labels on both ends of the cable should be properly positioned, with correct and clear contents. The numbers for both ends of the cable should be written on strap labels, which are tied 2cm behind the connectors respectively. See Figure 5-2 for details, and the labels should indicate the corresponding relations.


5-2

(1) Labels

Figure 5-2 Cable labels

3) All cables, especially the digital trunk cables and optical fiber pigtails, can not be excessively bent at turning points so as to protect the cable cores from damage. Figure 5-3 shows the bundling of subscriber cables at turning points.

(1) No bundling at the bend (2) Cable tie

Figure 5-3 Bundling of subscriber cables at turning points

4) Cable bending radius should be more than two times of its diameter. The bending radius near the connector outlet reaches 4~6 times. In general, it is more than 4cm. For optic fiber, the bending radius is more than 20 times of its diameter.

5) To bundle cables between the frames, three cable ties should be used for each frame, and the top one should be at the bend. The space between cable ties should be even and the buckles should be at the outer edge of the cable bundles.

6) Cable trough arrangement technique

First, clean the rubbish in the trough. And seal both ends to keep rat from damaging the cables.

All cables from the inlet of the trough to the inside of the cabinet should be arranged in good order. The cables should be of the same lengths in the trough. See Figure 5-4 for details.


5-3

Signal cables in the trough should be separated from power cables as far as possible. They should not be too close to each other (5cm distance at least), let alone being bundled together.

(1) Subscriber cable (2) Distribution frame (3) Trough

Figure 5-4 Schematic diagram of cable trough layout

1) The cables must be neatly arranged, without skin damage, and should not be pulled by force. Leave a certain margin and keep moderate bundling.

2) The cables can not be mixed, and cables of different kinds should be laid out separately.

3) The specifications, routes, cross sections and positions of cables should conform to the stipulations in the construction drawings. The cable arrangement and the use of ports should facilitate the future maintenance and capacity expansion.

4) The cables laid in walkway must be bundled. The bundled cables should be close and the appearance is regular. The spacing between cable ties is even with moderate tightness. Especially, the fiber pigtails should not be bundled too tightly. If flaxen thread is used as the binding material, it should be wax-soaked. Cables laid in trenches/troughs are not required to be bundled, but should be tidily arranged to avoid crossing-over if possible. The cables should be kept


5-4

within the trough. At the ingress and egress of the trough and the cable bend, the cables should be properly bundled and fixed with plastic fastener. Protection sleeves are required for the fibers distributed in the trough.

5) Cables should be bundled with an even spacing. Bundle the cables at every 8 square holes on the square-hole bar (for power cables and ground wires). At the back of the cabinet, bundle the cables wherever they go across a beam (for communication cables). The cable ties should be free of sharp tips and the buckles should point to the same direction if possible. Excessive optical fibers and cables should be tidily coiled up so that they can be found conveniently. Fiber pigtails that are not in use temporarily should be well protected. Cable connectors made on site must be firm, reliable and neat.

6) If the equipment room is installed with the anti-static floor, it is recommended that the subscriber cable adopt the lower cabling mode. Thus the cabling is elegant and easy to run. If the equipment is not installed with the support, the upper cabling method should be adopted, and the cable guide are installed over the cabinet. When the lower cabling mode is adopted, all cables pass through the floor interlayer or cabling trough. When the upper cabling is adopted, the cables pass through the upper cabling cabinet or lower cabling cabinet over the cabinet. The cabling standard, route, cross section and location should comply with the stipulations in the construction drawings. The cables must be arranged in order and there is no damage on the sheaths. The specifications, routes, cross sections and positions of the cables should conform to the stipulations in the construction drawings. The cables should be tidily arranged, without skin damage. The subscriber cables and the power cables should be arranged separately. The cables should be bent evenly and smoothly. The outside of the bent curve should be kept vertical. The minimum bend radius should be greater than 60mm.

5.2 Arrangement of Cables

5.2.1 Overview

The MA5100 frame is equipped with 16 slots, which are numbered, from left to right, as 0~15. Slots 7 and 8 are for the main control board exclusively. Other slots can be inserted with any service board. Both the main control board and the service boards adopt the front-panel-leading-out mode.

The MA5100 adopts the H66 Series cabinet, where cable is arranged as the follows:

1) Cable and optical fiber are led out from the front panel of the board. 2) The cable is routed to the wiring frame, then to the wire bushing at the two sides

of the cabinet, where it is bundled. 3) You can adopt downward routing or upward routing as required. Bundle the

cables at the two sides of the cabinet, and lead the cables out from the top or the bottom of the cabinet.

SPL user cables are front-access-cabled inside the cabinet. The SPL user cables out of the front panel of the SPL board are routed to the both sides of the cabinet from the cabling frame. These cables should be bundled along the both sides of the cabinet. They should not be bundled with power cables.

When inserting the ADSL cable plug, push it in horizontally without shaking to the right or left. When pulling the plug out, pinch the locker on the plug with your fingers, and then pull it out horizontally, shown as Figure 5-8.

Figure 5-8 ADSL board cable plug-in/pull-out diagram

Note

Wrong plug-in or pull-out operation may curve the pins. If feeling any relatively heavy pressure in the course of plug-in or pull-out, stop the operation, and check whether the pins are curved or broken off.

III. Installing ADLE/ADLG/ADLH/ADLJ/ADCE Cable

ADLE/ADLG/ADLH/ADLJ/ADCE has a built-in splitter module to realize voice splitting individually. This kind of borads use the same cable as ADLI cable. Figure 5-9 illustrates the board front panel.

Figure 5-9 ADLE/ADLG/ADLH/ADLJ/ADCE board silk-screen

The following points should be cautioned in ADLE/ADLG/ADLH/ADLJ/ADCE cabling in the case of full configuration of the cabinet:

Subscriber cables should be bundled tightly together. In a frame, it is recommended to first arrange cables of slots 6 and 9 (service slots in the middle) then cables of slots 5~0 and 10~15. The first arranged cables are put on the later arranged cable in bundling, so that too tight cable installation will not disturb board insertion and removal.


5-13

Corrugated tube is required when optical fiber enters the cabinet from the cable access hole on the left (recommended).

The power cord is recommended to enter the cabinet from the cable access hole on the right.

IV. Jumper of the ADSL Cable

For the purpose of installing ADSL user cables, it is required to install jumpers of the cables in the vendee’s equipment room. The jumpers for the aforesaid two categories of ADSL boards are different. The following describes the details.

1) Jumper of ADLI

Select an empty port in ADLI and cut off the jumper between the MDF at the office end and MDF at the customer end. Then connect the MDF at the office end with a PSTN port in SPL board using a jumper, and the MDF at the customer end with LINE port in SPL. Record the frame No., slot No. and port No. where the jumper is located. See Figure 5-10.

II. Installing LAND cable

The LAND board can be equipped with various subboards to provide a series of interfaces. It uses network cable and optical fiber, which can be installed as the follows:

1) Installing network cable

MA5100 10/100M Ethernet cable consist of straight-through cable and crossover cable. They are similar in cable structure, but different in cable pinouts.

The Ethernet cables are led out from the front panel of the boards in the cabinet. When the cables or fibers are led out from the panel of the LAN board, they are wired from the cabling frame under the MA5100 service frame, and led to the two sides of


5-17

the cabinet. The cables and fibers should be bundled along the sides of the cabinet, and separated from the power cables.

2) Connecting the fibers

When the subboards for optical interfaces are used, you should connect the fibers. The fibers for the LAND board are laid in the same way as that for the MMX/AIU. Refer to 5.3 Installing and Arranging Optical Fiber for details.

5.2.7 Installing IMU Cable

I. Introduction to the IMU board

The H511IMU board (IMU for short) is a service board of the MA5100. It provides 16-channel E1 electrical interfaces, which transmit ATM cells over E1 lines in ATM UNI/IMA mode for the purpose of IMA service provisioning. The IMU supports downstream cascading of MA5105s. However, it does not support the IMA uplink function.

II. Installing IMU Cable

Each IMU board is equipped with two 8-channel E1 trunk cables. One end of the cable uses DB68PIN connector, with spacing of 1.27mm. The other end uses either SMB connector or naked cable. When using SMB connector, the IMU cable is directly connected to a switch. When using naked cable, the IMU cable is directly connected to the MDF.

Three trunk cables are available:

Cable impedance is 75Ω, one end of the cable using SMB connector.


5-24

Cable impedance is 75Ω, one end of the cable using bare cable. Cable impedance is 120Ω, one end of the cable using bare cable.

Choose the proper cable type depending on the actual needs.

IMU cabling is performed in the front. It needs to be configured with two 8-channel E1 trunk cable. See Figure 5-16 for the cable structure.

The E1 cabling is performed in the front of the MA5100 cabinet. The E1 cable led out from the front panel is routed to the both sides of the cabinet through the cabling frame in the bottom of MA5100 frame. Bundle it along the left or right sides of the cabinet separately, and keep it away from the power cords and other unshielded signaling cables.

5.2.8 Installing E8IT Cable

When MMX and AIU are configured with the E8IT subboard for IMA service, it provides 8-channel E1 interfaces. 4-channel E1 trunk cable is needed. One end of the E1 cable uses DB50PIN connector to connect with DB50 interface in E8IT board. The other end uses either SMB connector or naked cable. When using SMB connector, the CESC cable is directly connected to a switch. When using naked cable, the CESC cable is directly connected to the MDF



5-26

Cable impedance is 75Ω, one end of the cable using SMB connector. Cable impedance is 75Ω, one end of the cable using bare cable. Cable impedance is 120Ω, one end of the cable using bare cable.


5.2.9 Installing Master-slave Subtending Cable

The subtending module mainly controls the access of slave frames of the MA5100. There are two master-slave subtending modes: SEPA/SMXB and SEPL/SMXL:

The SEPA board in the master frame is connected with the SMXB board in the slave frame through LVDS (IEEE 1394cables). Thus, the slave frame is subtended to the master frame. Messages between the service boards in the slave frames and the MMX in the master frame are transmitted through the SMXB and the SEPA boards.

The SEPL board in the master frame is connected with the SXML board in the slave frame through optical fibers. Thus, the slave frame is subtended to the master frame. Messages between the service boards in the slave frames and the MMX in the master frame are transmitted through the SMXL and the SEPL boards.

Note:

The frame ID of the master frame is fixed as 0, and the IDs of the slave frames range from 1 to 4. In the aforesaid two subtending modes, the slave frames are numbered differently. For details, refer to SmartAX MA5100/5103 Multi-service Access Module Operation Manual.

The following introduces the two subtending modes.

LVDS cables (IEEE 1394) are used to connect the SMXB board and the SEPA board for the purpose of subtending the master and slave frames.

The SMXB board’s active and standby ports SB0 and SB1 are used for subtending the master and slave frames. The SEPA board has four ports (SN0-SN3) in total.

When there are active and standby SEPA boards in the master frame, the cabling is as follows:

The SMXB uses two IEEE 1394 subtending cables. One is used to connect the SB0 port on the SMXB board and one port (assume SN0) of SN0-SN3 ports on the active SEPA board in the master frame. The other is used to connect the SB1 port on the

The H66 Series Cabinets are adopted for the MA5100. A cabinet can be installed with up to three service frames (the specific number of frames is determined according to the corresponding configuration). If subscribers are added by means of master-slave subtending, and another cabinet is needed, the two cabinets should be combined. The subtending cables should be routed through the combined cabinets.

5.2.10 Installing AIU Cable

I. Introduction to AIU Board

H511AIUA board provides ATM interfaces for remote cascading of MA5100. When configured with different subboards, it can provide a single-mode STM-1 optical interface, a multi-mode STM-1 ATM optical interface, two single-mode STM-1 ATM


5-30

optical interfaces, two multi-mode STM-1 ATM interfaces or eight E1 IMA interfaces. Silk screen on the board is shown in Figure 5-20.

Note:

AIUA supports at most two subboards, but you cannot configure two subboards which provide different types of interfaces, that is one of the STM-1 optical subboard, IAM subboard, APON subboard (here we see single-mode interface and multimode interface as the same type.).

AIUA supports 1~4 155M ATM optical interfaces, which work independently. That is, they cannot work in active/standby mode and also not in load-sharing mode. The first subboard must be of dual-interface type when three optical interfaces are required in configuration.

When configured with ATM subboard, optical fiber is used, see 5.3 Installing and Arranging Optical Fiber.

5.3 Installing and Arranging Optical Fiber

The MA5100 can be configured with one or two 155M ATM optical fibers. The optical fiber can not be bundled too tightly, and the flexure diameter can not be less than 40mm. Put the extra pigtail under the cabinet bottom neatly. When the optical fiber is installed outside the cabinet, it should be equipped with protective tube, and the protective tube shall be secured in the cabinet. The fiber is led out from the MMX optical interface, and led into the back of the cabinet through the cabling frame. Bundle the fiber along the left and right side of the cabinet. Make proper labels on the fibers.

6-1

Chapter 6 Checking Hardware Installation

When the hardware installation is completed, it is required to check the hardware installation to make good preparations for the subsequent software installation and system debugging. The checkup includes the following three aspects:

Making overall inspection Checking system power supply Checking system status after power-on

6.1 Making Overall Inspection

The overall inspection refers to review of the entire installation work. The check items include cabinets, cable distribution, connectors, sockets, labels, and site environment, which are described in detail in the following paragraphs:

I. Checking cabinets

The check points are as follows:

The installed cabinets should be stable and tidy. For multiple rows of cabinet, each row shall run parallel.

The vertical deviation of cabinets should be within 3mm. All cover plates and doors should be fit on the cabinets and be in a line, with the

deviation less than 5mm. Two adjacent cabinets should be fixed together closely. The front surface and back surface of the cabinets in the same row should be on the same plane.

Make sure that all the screws are fixed firmly, with flat and spring washers mounted properly.

The parts on the cabinets should be intact and in right place; the connection lines should not be damaged or broken; the labels should be correct, clear and complete.

The cabinets should be spotless. Fingerprints left during the installation should be cleaned up.

The cabling holes at the top and bottom of the cabinets should be covered to prevent small creatures (such as mice) from entering.

II. Checking cable distribution

1) Power cables and ground cables

This checkup covers all the power cables and ground cables which come from the AC/DC modules first to power distribution boxes on the cabinet back, then to the


6-2

busbars and to the power sockets on various backplanes. Make sure that all the power cables and ground cables are reliably and correctly connected.

2) Intra-module cables All cables are correctly connected and the connectors are free of loose

connection. All the cables are bundled properly and spacing between ties is appropriate. Cable ties are not overlaid, and have no sharp ends.

3) Cables and optical fibers Cables cannot be too tight at turn points. The wiring route should be correct and cables should be bundled with the same

interval. The cables inside the cabinets should be straight and smooth without crossover.

The cables outside the cabinets should be bundled together. The cables in the troughs or along the cabling ladders should be tidily arranged. All

cables should be bound properly without damage to the jacket. Proper surplus should be left for the cables. The cable ties should be cut with flush

ends and without superimposition.

III. Checking connectors and sockets

1) Connectors

The locking catches of the cable connectors should be firmly buckled and coaxial cable connectors should be fixed firmly.

2) Sockets

Check all the sockets to make sure that there is no broken pin and bent pins does not cause short circuit.

IV. Checking labels

All labels should be clean, clear and neatly arranged in proper position.

V. Checking site environment

1) Cabinets

No redundant cable tie end, cable end or other sundries is left in cabinets. The front and rear doors, side cover plates of cabinets should be clean with no stain, fingerprint and the like left.

2) Cabling trough

No engineering remnants, such as cable tie ends, cable ends and desiccant bags, should be left in the cabling troughs, under cabinets or the raised floor around cabinets.

3) Equipment room


6-3

Unnecessary materials should be dismissed out of the equipment room and necessary articles should be in order. The operation consoles should be clean and orderly, and raised floor should be smooth and clean.

After checking of the hardware installation, check the power system.

6.2 Checking System Power Supply

Power on the system after the hardware installation checkup is completed. The specific steps are as follows:

1) Set the main switch of the 220V AC or -48V DC power supply to OFF. 2) Set all the AC power sockets and power switches connected with the equipment

and terminals to OFF. 3) Pull out all the boards from the MA5100 case, or just loosely mount them in the

case, but make sure that board does not touch the pins on the backplane. 4) Test with a multimeter to determine whether short circuit exists between the phase

line (live wire), ground line and neutral line of each power socket. 5) If the 220V AC power supply is used, switch on the main switch of the 220V AC

power supply and measure with a multimeter to determine whether power voltage at the UPS (Uninterrupted Power Supply) input is normal. If it is normal, then switch on the UPS and measure whether the UPS output is normal. Switch on the switch of equipment power socket and measure with the multimeter to see whether the output is normal. At the point the input VIN ELD on the MA5100 rectifier module is ON.

6) If the -48V DC power supply is used, first test whether any short circuit occurs in the three PDF terminals (-48V, GND and PGND) with a multimeter. Then, switch on the main switch of the -48V DC power supply and measure with a multimeter to see whether the voltages between –48V DC and GND, -48V DC and PGND in PDF are normal (-40V~-57V).

6.3 Checking System Status after Power-on

After the system power supply is tested to be normal, proceed to check the system status.

1) If the 220V AC power input is normal, switch on the switch of the MA5100 rectifier module and the power switch of the cabinet. The green RUN LED (Light Emitting Diode) on the panel of each rectifier module should be ON, and the red ALM LED should be OFF all the time. The fans in the fan frame and in the equipment case start working. If any fan is abnormal, please take it out of the fan frame for test.

2) If the -48V DC power input is normal, turn on the power switch of the cabinet. At this time, fans in the fan frame in the equipment case should start working. If any fan is abnormal, please take it out of the fan frame for test.


6-4

3) Power off the equipment and mount the boards. Then switch on the power switch, and all LEDs on the board panels will light and the RUN LEDs flash.

7.4 Engineering Labels for Cables

Engineering labels are affixed to both ends of the various cables to identify the physical positions of cables on different devices. Labels on the cables facilitate correct and orderly connection of cables, and easy maintenance after the installation.

There are two types of engineering labels, specialized for the power cables and signal cables respectively. The power cables include the AC power cables and DC power cables (excluding the power cable that connects the distribution box and the cabinet).


7-25

The signal cables include external cables of alarm box, Ethernet cables, optical fibers, trunk cables and subscriber cables (excluding the antenna feeders).

Note:

In case there is special requirement from the user of the equipment on the description method of the labels, the labels should be printed accordingly. However, this must be stated in the self-check report.

7.4.1 Introduction to Labels

I. Material

Material: Polyester (PET), with UL and CSA certifications Color: chalk white Thickness: 0.09mm Ambient temperature: -29~149 degrees Celsius Laser printing or handwriting with oiliness markers

II. Type and Shape

There are two types of engineering labels for power cables and signal cables respectively.

1) Label for signal cables

The label for signal cables is L-shaped with fixed dimensions, as shown in Figure 7-29 (expressed in mm).

TO：

(1) Dividing line (2) Cut dotted line

Figure 7-29 Label for signal cables

The dividing lines on the label help to specify more clearly the position of a cable. For example, there is one between the cabinet number and the frame number and another one between the frame number and the slot number. The dividing line is 1.5mm×0.6mm in size with the color of PONTONE 656c (light blue).


7-26

The cut dotted line helps to fold the label when affixing it to the cable, and its size is 1.0mm×2.0mm.

There is a mark “TO:” (upside down in the figure) at the lower right corner of the label. The mark is used to identify the opposite end of the cable on which the label is affixed.

2) Label for power cables

The label for power cables should be attached to the identification plate on the cable ties that are bundled to the cable. The identification plate has an embossment of 0.2mm×0.6mm around (symmetric on both sides), and the area in the middle is for affixing the label, as shown in Figure 7-30 (expressed in mm):

7.4.2 Printing Labels

The contents can be printed or written on the labels. Printing is recommended for the sake of high efficiency and eye-pleasant layout.

I. Template for the printing

The Word-form template is available for label printout. You can download the template from http://tech-support.huawei.com/asp/comm/index.asp (path://support/ document/project management/installation and maintenance/document/others), or get the template from Huawei local office.

When using the template, you can directly modify the contents on the template, and the following should be observed:

The settings of centered characters, direction, and fonts should not be changed. When there are too many characters to be filled in, zoom out the characters, but

make sure the printouts are clear and legible.


7-27

II. Cells merging on the template

To merge the cells, you should first recover the table structure (if gridlines are displayed, you can start from Step 3 directly).

1) Select the menu item [Edit/Select All]. 2) Select the menu item [Format/Borders and Shading/Borders]. Select Box and

click <OK>. 3) Drag the mouse to select the cells to be merged and select the menu item

[Table/Merge Cells].

If two merged cells are still not enough to accommodate the characters, use multiple lines.

III. Requirements on the printer

To print the labels, laser jet printer must be used, although there is no restriction on the model of the printer. Before printing the label, set up the page and try the printing on ordinary blank paper (both sides are blank):

1) Cover the blank paper onto the whole page of label paper, and check whether the page setup conforms to the requirement.

2) Make sure the printer properties, such as "paper size" and “direction”, have been set correctly.

3) If the warning prompt as shown in Figure 7-31 appears before printing, click <Ignore> to continue the printing.

Figure 7-31 Warning prompt before printing

If the printout confoms to the requiremnt, print it to label paper. If the printout does not conform, adjust the page setup and try the printing again, until the correct printout is produced. The method of adjusting the page setup is as follows:

1) Select the menu item [File/Page Setup]. 2) Select the Margins tab page. 3) Select Left for Gutter Position. 4) Set Header and Footer as 0, and adjust the values of Top, Bottom, Left, and

Right.

After the page setup has been made correct, save it for future use. This page setup is only necessary in the first time you use the template to print the labels.


7-28

IV. Requirements on feeding the printer

Different from the ordinary paper, the label paper is composed of two pages. No matter what model of printer you are using, feed in the labels one after another by hand. Never use the auto-feed mode in order to avoid jamming the labels. Different models of printers may have different feeding modes, make sure to feed in the labels correctly.

V. Requirements on the printed label

Make sure the printed label satisfy the following requirements:

All the printouts must be on the label, and nothing should be printed on the bottom page of the label.

Contents in the cells should be aligned in the center. In a single-line printout, the dividing lines and the mark “TO” should not be covered by the printed characters.

When the cells are merged and the printouts are made in multiple lines, avoid covering the mark “TO” when printing the texts by using the space bar to move the printing contents to the next line.

7.4.3 Writing Labels

Use the black oiliness markers delivered together with the device to write the labels.

In special cases, black ball-pens are allowed, although not recommended. When writing with the ball-pen, take care not to leave the oil on the label, which may contaminate the label and blur the words..

Note:

The delivered marker has two nibs. Make sure to use the smaller nib to write the labels.

For the sake of easy recognition and good looking, the font in handwriting should be close to the standard typeface as much as possible. Table 7-14 shows the standard typeface.

7.4.4 Affixing Labels

After printing or writing the label, remove the label from the bottom page and affix it to the signal cable, or the identification plate of the power cable.

I. Affixing the label to the signal cable

The steps to affix the label to the cable are shown in Figure 7-33, Figure 7-34 and Figure 7-35. The finished labels should be on the right or top of the cables, according to different cabling methods. The left part of the figures shows the method to affix the label when the cable is laid vertically, while the right part of the figures shows the method to affix the label when the cable is laid horizontally.

The label is affixed 2cm from the connector on the signal cable. In special cases, for example, to avoid cable bent or affecting other cables, other positions are allowed to affix the labels.

1) Stick the label to the proper position on the cable, fold the narrow part of the label according to the directions shown in Figure 7-33.

II. Affixing the label to the power cable

Remove the label from the bottom page, then affix it to the identification plate on the cable tie. The label should be stuck to the rectangular flute, and should be stuck to only one side of the identification plate. Make sure to affix the labels on the same side of the identification plates. The cable ties are bundled at 2cm from the connectors, and other positions are allowed in special circumstances.


7-31

Cable ties should be bundled on both ends of a cable. After the bundling, the finished identification plate should be on top of the cable in horizontal cabling, or on the right side of the cable in vertical cabling. Make sure the label is facing out, as shown in Figure 7-36.

7.4.5 Information Carried on Labels

I. For signal cables

The two sides of the label affixed on the signal cable carry information about the location of the ports connected to both ends of the cable, as shown in Figure 7-37.

The information is given like this:

Area 1 contains the location information of local end of the cable. Area 2 (with the mark "TO:") contains the location information of the opposite end

of the cable. Area 3 has been folded up inside the label.

Area 3Area 1

Area 2 TO:

Figure 7-37 Printed parts on the label for signal cables

Seen from the cabling end of the equipment, the text part of the label is on the right side of the cable. The side with “TO:” that is facing outside carries the location information of


7-32

the opposite end; and the other side carries the location information of the local end. Therefore, the information in Area 1 at one end is the same as the information in Area 2 at the other end of the cable, and vice versa. In other words, the local information at one end is called the opposite information at the other end.

II. For power cables

Labels for power cables are only affixed on one side of the identification plates. On the labels, there is information (the part after the mark “TO:”) about the location of the device on the other end of the cable, like the location of control cabinet, distribution box or power socket.

7.4.6 Remarks

When printing/writing and affixing labels, pay attention to keep the labels clean. Since the label paper is made of moistureproof and waterproof material, ink-jet

printers and ink pens are forbidden for printing and writing labels. Labels should be affixed with good order in alignment. Cable ties should be bundled in the same position of power cables, with

identification plates on the same side. The positions of “up”, “down”, “right” or “left” are all based on the viewpoint of the

engineering person who is working on the label.

7.4.7 Engineering Labels for External Cables of Alarm Box

The external cables of alarm box are connected with the first subscriber cabinet of each row (used for power distribution). Labels pasted on the first cabinet of each row should indicate which equipment is using the access terminal. Labels are not needed on the equipment side unless there is special requirement. In this case, only Area 2 of the label should be filled in.

Table 7-15 shows the information on the labels of alarm box external cables.

Table 7-15 Information on labels affixed to the external cables of alarm box

Content Meaning Example

MN MN: serial number of the cabinet in the machine room

M: The cabinets going from front to back (in a row) in the machine room are numbered from A to Z.

N: The cabinets going from left to right (in a column) are numbered from 01 to 99.

For example, A01 is the cabinet in Row A and Column 01.


7-33

Note:

Generally, the above numbering method is enough to identify the position of a specific cabinet. If cabinets are installed in a back-to-back manner, the facing direction of the cabinet must be specified, the numbering method like MNO is used. Here, “O” means the direction of the cabinet, which can be “A” or “B”. On the cable labels described below, this numbering method is used, unless otherwise stated.

The label on the alarm cable carries simple information, and only part of the text area needs to be filled in. It is recommended to keep the whole length of the label instead of cutting out the blank area.

Figure 7-38 shows a label on the alarm cable, on which “A01” indicates that the alarm cable is connected from the first cabinet to the cabinet on Row A, Column 01 in the machine room.

Figure 7-38 Example of the label on the alarm cable

7.4.8 Engineering Labels for Ethernet Cables

If the cable is connected to the Network Management Station (NMS), specific location of the NMS should be given.

In VAS products, the information provided on the labels is different, subject to different devices that the Ethernet cables are connecting.

Labels for the Ethernet cable that connects the HUB and the server 1) The label on the HUB end should indicate the number of the frame and cabinet

where the HUB locates, and the serial number on the HUB. 2) The label on the server end should indicate the number of the frame and cabinet

where the server locates. In case it is a stand-alone server, specific position of the server should be provided.

Labels for the Ethernet cable that connects the HUB and the agent 1) The label on the agent end should contain the serial number of the Ethernet port.

The definitions of the cabinet number and frame number are the same as those described in Table 7-16 above.

2) If it is a stand-alone HUB without any cabinet or frame, the label should contain specific location information that identifies the HUB.

3) The serial number on the HUB, the network port number of the agent and the location of stand-alone server should be specified according to actual connection.

7.4.12 Engineering Labels for Power Cables

I. Labels for DC Power Cables

The labels are affixed to the DC cables that provide power for the cabinets, and the protection grounding cables, including the -48V, PGND, and BGND cables. The labels for DC power cables are affixed to one side of the identification plates on cable ties.


Table 7-22 shows the information carried on the labels for the DC power cables:

Table 7-22 Information on labels affixed to the DC power cables

Content Meaning

MN(BC)--48V1

MN(BC)--48V2

MN(BC)-BGND

MN(BC)-PGND

MN(BC): BC is written right under MN.

On the loaded cabinet side, only MN is used to identify the cabinet.

On the power cabinet side, MN identifies the row and column number of the power distribution equipment like the control cabinet and distribution box, BC identifies the row and column number of the -48V connecter (if there is no row number or column number, or the connecter can be identified without them, BC can be omitted). BGND and PGND have no row and column number for identification.

The label only carries location information about the opposite equipment, the control cabinet or the distribution box, while information of the local end is not necessary. Table 7-22 lists the information of two -48V power supplies on the label. The information for other DC voltages (such as 24V, 60V) should be given in similar methods.


Make sure that labels are affixed in correction direction. That is, after the cable ties are bundled onto the cable, the identification plates with the labels should face up, and the text on the labels in the same cabinet should be in the same direction, as shown in Figure 7-45.


7-42

(1) (2)

TO: A01 -48V2 B08

TO: B03 -48V2

Figure 7-45 Example of the labels on the DC power cable

In Figure 7-45, (1) indicates the label on the loaded cabinet side, which carries the information about the position of the cable on the power distribution box. (2) indicates the label on the distribution box side, which carries the information about the position of the cable on the loaded cabinet side.

On the loaded cabinet side, the label marked with “A01/B08--48V2” on the cable indicates that the cable is -48V2 DC supply, which is from the 8th connecter on the second row of -48V bus bar in the cabinet on Row A, and Column 1 in the machine room.

On the distribution box side, the label marked with “B03--48V2” indicates that the cable is -48V2 DC supply, which is from the loaded cabinet on Row B, Column 03 in the machine room.

Note:

In the power distribution box (or the first power cabinet of a row in the transmission machine room), every terminal block on the -48V connector bar has a numeric identification. For example, in the above label of “A01/B08--48V2”, “08” (or sometimes “8”) is the numeric identification of the terminal block.

PGND and BGND are two copper bars, on which the terminal blocks are short-circuited, therefore which terminal is connected makes no difference. It is only necessary to give the row and column of the power distribution box, instead of giving the specific serial number of the terminal block on the copper bar. For example, if the label on the loaded cabinet side is “A01-BGND”, it means that the power cable is a BGND that connects BGND copper bar in the power distribution box on Row A, Column 01 in the machine room. Information on the labels for PGND cables should be given in the similar way.


7-43

II. Labels for AC Power Cables

The labels are affixed to the AC cables that provide power for the cabinets, and the protection grounding cables, including the 110V/220V AC, PGND, and BGND cables. The 110V/220V AC cables and related PGND and BGND cables are covered with insulating sheath, so the labels only need to contain the words of “AC" and the cabinet number. The labels for AC power cables are affixed to one side of the identification plates on cable ties.


Table 7-23 shows the information carried on the labels for the AC power cables.

Table 7-23 Information on labels affixed to the AC power cables

Content Meaning

MN-AC

MN: serial number of the cabinet or the socket where the power is led in

The location of the socket is marked out according to onsite situation. If the sockets can be identified by row number and column number, they can be numbered following the same rule for the cabinets. If the sockets cannot be identified by rows and columns, specify the detailed locations to avoid confusing with other sockets.

The label only carries location information about the opposite equipment and the power socket, while information of the local end is not necessary.


Make sure that labels are affixed in correction direction. That is, after the cable ties are bundled onto the cable, the identification plates with the labels should face up, and the text on the labels in the same cabinet should be in the same direction, as shown in Figure 7-46:

TO: A01 AC

TO: B01 AC

(1) (2)

Figure 7-46 Example of the labels on the AC power cable

In Figure 7-46, (1) indicates the label on the loaded cabinet side, which carries the information about the position of the cable on the power socket. (2) indicates the label on the power socket side, which carries the information about the position of the cable on the loaded cabinet side.


7-44

On the loaded cabinet side, the label marked with “A01-AC” indicates that the power cable is connected to the socket of Row A and Column 01 in the machine room.

On the power socket side, the label marked with “B01-AC” indicates that the power cable is connected to the loaded cabinet of Row B, Column 01 in the machine room.
