III. Drilling holes

To fix supports onto ground with M12 expansion bolts, it is required to drill holes for the expansion bolts using a percussion drill with bit φ16.

To drill a hole, do as follows:

1) Keep the drilling bit vertical to the ground and hold tight the drillstock to make holes 52 mm to 60 mm deep. The depth of the holes must be within 52 mm to 60 mm. Otherwise the expansion bolts cannot be fastened. Make sure that the depths of all holes are the same.

2) Clean the dust inside the holes with a vacuum cleaner. 3) Measure the depth to make sure that the depths of all holes are the same.

If the ground is too hard or smooth to settle the drill bit, punch a sample pit first for easy drilling.



3-6

Drawing lines and drilling holes are the fundamental work for hardware installation. Good quality is the prerequisite to guarantee the quality of the overall installation. If the accuracy is not high enough, the future work will be greatly affected.

Note:

The depth of drilled hole must be 52 mm to 60 mm. A depth less than 52 mm or more than 60 mm will cause the expansion bolt unable to be installed or fastened.

3.3.4 Installing Supports and Slide Rails

I. Installing expansion bolts

Before fixing expansion bolts, clean up the dust inside and around the holes with a vacuum cleaner. Measure the distance between the holes, and place the supports to check whether the supports and holes match exactly. For the holes with big deviation, plan and drill new holes before installing expansion bolts in them.

To install an expansion bolt, do as follows:

1) Take expansion tube and nut off the expansion bolt, and put them vertically into a hole after guiding rib on expansion nut has been inserted in to guiding slot of the expansion tube.

2) Strike directly on expansion tube with a rubber hammer until it is completely driven into the ground.

Figure 3-5 shows the installation of expansion tube and expansion nut.

Note:

The guiding rib on expansion nut must be inserted into the guiding slot on expansion tube before the tube is driven into the ground. Otherwise, the expansion bolt could not be installed and fastened normally.

II. Adjusting support height

To ensure that the upper surface of slide rails and the upper surface of ESD-preventive floor are on the same level after the supports and sidle rails are assembled, it is required to adjust all the supports to the preset height before installation.

To adjust the support height, do as follows:

1) Measure the height of the upper surface of the ESD-preventive floor. 2) Make the value minus the height of the slide rail (50 mm) to get the preset height of

the supports. 3) According to the ESD-preventive floor height mark on the supports, adjust all the

supports to the preset height and tighten the height-locking bolts to 45 Nm with a torque spanner.

4) Tighten the bolts in the middle and then those at both sides, as shown in Figure 3-6.

4.2.3 Installation Notices

When installing internal components, it is required to place each component with care into corresponding guide rails in the cabinet, and then insert it slightly into the cabinet. The component installation sequence inside the cabinet is from bottom upward for the sake of cabinet stability and convenience in operation.

When fixing internal components and blank filler panels, it is required to put the bolts into the installation holes on the mount angles of each component, and then fix the component on the mount angles at both sides of the cabinet. If there are more than two bolts for a component, it is required to first fix the four bolts at the four corners in diagonal direction, and then fasten other bolts in sequence.

Blank filler panel is fixed on the mount angles at both sides of the cabinet by lockers. To pull out blank filler panel, you must first press down the lockers and then loose them.



4-6

During installation, you must ensure the mount angles in correct order, to keep even space between components, between blank filler panels, and between component and blank filler panel.

4.3 Installing Internal Components

4.3.1 Installation Requirements

5.2.1 Introduction to Power Supply System

I. Power Supply Path of PDF

All SoftX3000 cabinets are N68-22 cabinets. Generally, an N68-22 cabinet is powered by two independent –48V DC power. The power of the components in the cabinet is controlled by the power distribution frame (PDF). Figure 5-1 shows the power supply path in a PDF.

-48V1

-48V2

Power distribution frame

SW1 SW2 SW3 SW4 SW5 SW6

Figure 5-1 Power supply path of a PDF

To enhance the reliability of the power supply to internal components of the cabinet, the PDF combines two input power into one using a large-power diode, and exports to the six power switches (SW1–SW6) on its panel through a power bus cable. Each of the six




5-2

switches power some of the components in the cabinet. When one of the input power fails, the other can still power the internal components of the cabinet.

II. Power Supply Path in the Cabinets

There are three types of SoftX3000 cabinet—integrated configuration cabinet, service processing cabinet, and media resource server (MRS) cabinet. The components configured in these cabinets are different from one another, and so does their (primary) power supply system. Figure 5-2 shows the details of the (primary) power supply system in the cabinets.

5.2.2 Introduction to Protection Grounding System

The SoftX3000 equipment adopts joint grounding mode. The protection grounding cables for each cabinet are connected to DC power distribution cabinet that conducts grounding, and all cabinets are connected by protection grounding cables as an equipotential system.

The input terminals of backhaul ground (BGND) and protection ground (PGND) of the cabinet have been connected before delivery to ensure they are equipotential. The protection grounding cables of the internal components of a cabinet are interconnected through the grounding bars on the side columns of cabinets. Through the protection grounding cables of the cabinet, the grounding bars are connected to the protection ground of the DC power distribution cabinet, which is connected with the protection grounding bus in equipment room.




5-4

The protection grounding cables of a cabinet include:

Protection grounding cables for service frames, Protection grounding cables for iGWB and BAM, Protection grounding cable for KVMS, Protection grounding cable for LAN Switch, Protection grounding cable for MRS, Protection grounding cables for cabinet doors, and Protection grounding cables for connecting grounding bars of adjacent cabinets.

Refer to Refer to chapter 4 “Cables” of U-SYS SoftX3000 SoftSwitch System Hardware Description Manual for the appearances, models, and specifications of protection grounding cables.

5.3.2 Installation Notices

Generally, DC power distribution cabinet is provided by the customer. If DC power distribution cabinet is provided together with the SoftX3000 equipment, refer to its delivery-attached manuals.

The protection grounding bar of DC power distribution cabinet must be correctly connected to the nearest protection grounding bar offered by the customer through PGND grounding bus cable. The protection grounding cable uses green and yellow plastic insulation copper core wires whose core area is the same as that of power cable.

The internal power cables of N68-22 cabinets have been connected to the corresponding connecting terminals of power distribution frames before delivery. After the internal components have been installed completely, connect the other ends of the power cables to the components.

Before installation, mark or stick labels on both ends of each power cable and protection grounding cable to identify the device that the cable is connected to, and to ensure correct connection. For information about filling in and sticking engineering labels, refer to Appendix B "Engineering Labels for Cables" in this manual.

Only trained professionals can hot-line work on devices with –48V power terminals like the PDF and service frames.

5.3.3 Installing Power Cables for Internal Components

I. Installing power cable for service frame

Service frames include basic frame and expansion frame. Each service frame has one input power cable when single power supply is adopted, and has two input power cables when dual power supplies are adopted. The power cables that are connected to the frames in different locations have different lengths. Figure 5-4 shows the appearance of the power cable.

Figure 5-4 Appearance of power cable for service frame

To install protection grounding cables between cabinets, use 10AWG cables (300 mm long) to connect the upper, middle, and lower parts of the grounding bars of adjacent cabinets, as shown in Figure 5-18.

5.3.6 Installing Power Cables and Protection Grounding Cables for Cabinets

I. Introduction to installing power cables for cabinets

There might be two cases when you install power cables and protection grounding cables to a cabinet, that is, if DC power distribution cabinet is provided together with the SoftX3000 equipment, and if only DC power switchboard is configured in the equipment room. For detailed information, see the contents later in this section.

II. Connecting cables from DC power distribution cabinet to SoftX3000 cabinet

Note:

Before connecting power cables and protection grounding cables, measure the distance between protection grounding bar and power distribution cabinet, and the distance between DC power distribution cabinet and connecting terminals of the power distribution frame in the cabinet. If a used cable is not long enough, stop your work and replace it with a new one. Do not splice cables by connectors or soldering. It is required to stick labels at both ends of a power cable where they are 30 mm away from the root of the cable.

Figure 5-18 shows the connection of power cables from the DC power distribution cabinet to the SoftX3000 cabinet.

The following describes how to connect power cables and protection grounding cables from DC power distribution cabinet to a SoftX3000 cabinet:

1) Insert the cord end terminals (as shown in Figure 5-19) of the two blue power cables into the connecting terminals marked “–48V1” and “–48V2” on the power distribution frame in the cabinet and fasten them.

2) Connect the other ends of the two blue cables to the corresponding output connectors marked “–48V1” and “–48V2” in the DC power distribution cabinet, for example, the “–48V1” and “–48V2” power cables in the third cabinet must be connected to the third output connectors of “–48V1” and “–48V2” in the DC power distribution cabinet.

Figure 5-19 Cord end terminal of power cable




5-17

3) Use the black BGND cables to connect the connecting terminals marked “BGND” on the power distribution frame of the cabinet, and the GND grounding bars in the DC power distribution cabinet.

4) Connect one end of the protection grounding cable (yellow or green and yellow) to the connecting terminal marked “PGND” in the power distribution frame of the cabinet, and connect the other end to the protection grounding bar in the equipment room.

For –48V1 and –48V2 connecting terminals, it is required to use the upper group first, and then the lower group. For each group, it is required to use the connecting terminals from left to right (viewed from the front side) one by one. The terminals for positive line bank and lightning protection ground are used sequentially from left to right.

Note:

In other cases when power cables are led from DC power distribution cabinet, (for example, to connect protection grounding cables for a terminal), reverse principle is applied, that is, the terminals are used from down to top and from right to left, to facilitate future expansion and connection.

If DC power distribution cabinet is not configured in the equipment room, do as follows:

1) Connect the power cables led from –48V1 and –48V2 connecting terminals of the SoftX3000 cabinet to –48 VDC negative line bank of DC switchboard (or DC power supply);

2) Connect the power cable led from GND connecting terminal of the SoftX3000 cabinet to –48 VDC positive line bank of DC switchboard (or DC power supply);

3) Connect the protection grounding cable led from the PGND connecting terminal of the SoftX3000 cabinet to the protection grounding bar nearby provided by the customer. The cable material must be the green and yellow plastic insulation copper core wire whose core area is the same as that of power cable.

III. Laying power cables and protection grounding cables at SoftX3000 sdie

When downward cabling is used, the steps to laying power cables and protection grounding cables at the SoftX3000 cabinet side are as follows:

1) Lead the power cables and protection grounding cables into the cabinet through rodent-proof net at the bottom of the cabinet.

2) Lay the power cables and protection grounding cables along the cabling troughs on the side columns of the cabinet until they reach the top of cabinet.

3) Connect the power cables and protection grounding cables to the corresponding connecting terminals in the power distribution frame.




5-18

When upward cabling is used, the steps to laying power cables and protection grounding cables at the SoftX3000 cabinet side are as follows:

1) Lay the power cables and protection grounding cables on the top of cabinet. 2) Connect the protection grounding cables to the grounding bolts. 3) Lead the protection grounding cables out from the grounding bolts. 4) Pass the power cables and protection grounding cables trough the cabling holes in

the top of the cabinet. 5) Connect the power cables and protection grounding cables to the corresponding

connecting terminals in the power distribution frame.

To lay the power and protection grounding cables, straight and even appearance is required, and different colors must be separated, and the cables must be bound every 200 mm.

After the power and protection grounding cables are laid out, it is required to cut the rubber cover to match the size of the left space of the cabling hole.

Note:

When power cables and protection grounding cable are laid outside cabinet, they must be bound separately. When cables are laid inside cabinet, power cables and protection grounding cable are bound separate from signal cables.

IV. Laying power and protection grounding cables in DC power distribution cabinet

To lay the power cables and protection grounding cables in the DC power distribution cabinet, do as follows:

1) Lead the power cables (settled according to colors) into DC power distribution cabinet through cabling holes in the top of the cabinet

2) Lay and bind the power cables along the side columns, until they reach corresponding bus bars.

3) Lay and bind them along the beam of the cabinet. Ensure that the cables are laid inside the cabinet with smooth and uncrossed appearance.

4) Add flat washers and spring washers to connect OT terminals to GND copper bus bar and –48V wire post.




5-19

Note:

When power cables and protection grounding cable are laid outside cabinet, they must be bound separately. When cables are laid inside cabinet, power cables and protection grounding cable are bound separate from signal cables.

It is required to keep proper redundancy for the cables, and to cut out the surplus parts. When you make an OT terminal for a cable, be sure to cover it with heat-shrinkable tube, solder it (soldering is not allowed when you make a cable with large core area), and shrink the heat-shrinkable tube.

5.4 Installing Power Bus Cables from DC Power Distribution Cabinet to DC Switchboard

5.4.1 Introduction to Power Bus Cables from DC Power Distribution Cabinet to DC Switchboard

Power bus cables are used to connect DC power distribution cabinet and DC switchboard.

Generally provided by the customer, a power bus cable in the power room includes –48 VDC cable (blue) and BGND cable (black). The specifications of power bus cables are determined according to the result of site survey.

Note:

The core area of power bus cable from DC switchboard to DC power distribution cabinet is designed according to the parameters such as loop length of the power bus cable, terminal load payload capacity for the engineering and design voltage drop.

If a large-core-area power cable is required, you can connect two or more power cables in parallel to meet the requirement. For example, if there are only 120 mm2 power cables, but a 240 mm2 power cable is required, you can use two 120 mm2 power cables in parallel connection as one power cable.

Refer to Appendix C Calculating Core Area of Power Bus Cable for the calculation of core area of power bus cables.

Figure 5-20 Connecting terminals in DC power distribution cabinet

Two groups of primary power supplies are used for a DC power distribution cabinet, and there are five bus cables: one –48V1 bus cable, one –48V2 bus cable, two GND bus cables and one PGND bus cable.

The following describes how to connect the power bus cables between the DC power distribution cabinet and the DC switchboard:

1) Connect –48V1 bus bar in the DC power distribution cabinet to –48 VDC negative line bank in the active DC switchboard (or active DC power supply),




5-21

2) Connect –48V2 bus bar in the DC power distribution cabinet to –48 VDC negative line bank in the standby DC switchboard (or standby DC power supply).

3) Connect the GND bus bars in the DC power distribution cabinet to the –48 VDC positive line banks in the active and standby DC switchboards (or active and standby DC power supplies) respectively.

If there is only one power supply device, connect both of the –48V1 and –48V2 bus bars of the DC power distribution cabinet with the –48 VDC output terminals of the DC switchboard (or DC power supply).

Note:

The PGND grounding bar of the DC power distribution cabinet must be reliably connected to the protection grounding bar provided by the customer through grounding bus cable.

5.4.3 Making and Fixing OT Terminals

To make an OT terminal for a power bus cable or protection grounding cable at DC power distribution cabinet side, do as follows:

1) Cover the cable with a heat-shrinkable tube. 2) Solder (soldering is not allowed when you make a cable with large core area) or

press the OT terminal tightly. 3) Shrink the heat-shrinkable tube, and ensure that no bare wires or OT terminal

handle exist.

To fix an OT terminal at DC power distribution cabinet side, add flat washers and spring washers to make the terminal fixed firmly, and to ensure secure contact, as shown in Figure 5-21.

Note:

Proper redundancy for power bus cables can be kept at bending angles, but other surplus parts must be cut out. If the surplus parts are cut out, OT terminal must be remade.

5.4.4 Requirements for Installing OT Terminals

If it is necessary to install two or more cables on a wire post, install the OT terminals crosswise or back-to-back without being overlapped. If the OT terminals have to be overlapped, bend the terminals by 45 degree or 90 degree and install the biggest OT terminal at lower position. This rule is adaptable to all situations where OT terminals are installed. Figure 5-22 shows the overlapped OT terminals.

5.4.5 Requirements for Laying Cables Inside DC Power Distribution Cabinet

The requirements for laying cables inside DC power distribution cabinet are as follows:

The cables laid inside DC power distribution cabinet are smooth and not crossed, and the cables in different colors are bound separately.

Proper redundancy for cables is kept and the surplus parts are cut out. Both ends of a cable have labels made by Huawei Technologies and marked

corresponding serial number. The labels are stuck 30 mm away from the cable root.

The cables are bundled by different cable ties according to the actual conditions. The cable ties face the same direction after the cables are bundled, and the burrs of the cable ties must be sheared.

Except for the LAN Switch, the cables in Figure 6-1 are all connected at the back of the cabinet. The straight through network cables between LAN Switches connect the network ports in the GE subboards marked Slot1 at the back of the LAN Switches. These cables are indicated in Figure 6-1.

6.3 Requirements and Modes of Laying Signal Cables

6.3.1 Requirements for Laying Signal Cables

Each cable must be marked or stuck with engineering labels at both ends before it is installed, to indicate the connected equipment and sequence. For detailed information, refer to Appendix B “Engineering Labels for Cables” of this manual.

Different types of cables (for example, power cable, signal cable and protection grounding cable) must be bound separately. If the cables are laid inside the cabinet, the power cables and protection grounding cables must be bound separate from the signal cables.

When cables are laid vertically, they must be laid and bound along the left and right columns. When cables are laid horizontally, they must be laid and bound along the binding bars.



6-4

If power cables and signal cables are laid in a groove, they must not be bound together, and a distance of at least 50 mm between them must be ensured.

Joint parts of connectors must be secure and in good contact.

Cables must be bound in order and with proper tightness.

6.3.2 Modes of Laying Signal Cables

There is one rectangle cabling holes at each of the four corners on the top of cabinet and of the four corners at the bottom of cabinet. All the cabling holes have rodent-proof nets. Figure 6-2 shows the positions of the four cabling holes on the top of as cabinet as indicated by arrows.



6-5

Figure 6-2 External cabling holes on the cabinet

According to the actual conditions of the equipment room, the cables led in and out of cabinet can be laid through the cabling holes on the top or bottom of cabinet.

To lay the cables, lead the cables into the cabinet through the two back cabling holes on the top or bottom of the cabinet, and lay them along the side columns of the cabinet into corresponding cabling frame under each LAN Switch. Then, lay the cables through the cabling frames and insert them into corresponding sockets on the front panels of LAN Switches. Be sure to get the cables in order and fix them in the wire bushing.



6-6

At the cabling holes, there is rodent-proof net, through which cables shall pass. The size of the cabling holes must be proper so that no space is left around the cables.

The external cables are laid through cabling trough or cabling rack. For the methods for installing cabling rack, refer to Appendix A “Installing Cabling Rack” in this manual.

6.4.2 Installing Straight Through Network Cable Between LAN Switches

The two S3528G LAN Switches are interconnected through three straight through cable, and they work in dual backup mode. The dual backup mode, which is adopted to ensure data security, means that the two LAN Switches detect each other's heartbeat signals.



6-8

The three straight through cables respectively connects the FE interfaces 22, 23, and 24 of the two S3528G. Table 6-2 shows the connection mapping between the two LAN Switches.

Table 6-2 Connection mapping of straight through cables between the two LAN Switches

0＃LAN Switch 1＃LAN Switch

22 22

23 23

24 24

Before delivery, the FE interfaces 22, 23, and 24 of the two S3528G have been bound logically as three interfaces. This ensures the security and reliability. If you want to modify the settings of the two LAN Switches, refer to U-SYS SoftX3000 SoftSwitch System Part Replacement Guide for details.

6.4.3 Installing Straight Through Network Cable Between iGWB/BAM Server and LAN Switch

The integrated configuration cabinet has three servers: two iGWB servers and one BAM server. Each server uses two straight through network cables to connect with the active and standby LAN Switches. The upper network port is connected to LAN Switch 0, and the lower network port is connected to LAN Switch 1, as shown in Figure 6-1.

Because the ports of LAN Switches are arranged on the front panels, while the ports of the servers are arranged on the back panels of the servers, back cabling is required to lay the network cables which connect the servers and LAN Switches.

To install a pair of cable for a LAN Switch and a server, do as follows:

1) Insert the crystal connectors at one end of the network cables into the ports of the LAN Switches, and leave some surplus.

2) Lead the cables through the cabling frame under each LAN Switch to the back of the cabinet.

3) Separate the cables and lay them downward along the vertical cabling troughs at both sides.

4) Insert the crystal connectors at the other end into corresponding ports of a server, as shown in Figure 6-4.

The cable connection positions on the front panel of the LAN Switch depend on the port configuration scheme.



6-9

Figure 6-4 Connection position of straight through network cable on server

Note:

The BAM and the emergency workstation connect the LAN Switch with straight through cables. In this way, the emergency workstation can back up the data from the BAM.

Connect two straight through cables with the emergency workstation and leave them disconnected from the LAN Switch when the BAM is normal. When the BAM is faulty, immediately connect the two cables with the active and standby core LAN Switches. Refer to Figure 8-1 in chapter 8 for the cable connection of the emergency workstation.

6.4.4 Installing Straight Through Network Cable Between LAN Switch and HSCI

The service frames in the SoftX3000 communicate with each other through LAN Switch and the service boards are connected to LAN Switch through network ports.

In the integrated configuration cabinet and service processing cabinet, each of the active and standby HSCIs in both basic frame and expansion frame has six 10/100Mbit/s network ports. The ports marked 10/100BT6 at the uppermost position of the active and standby HSCIs are connected to the active and standby LAN Switches respectively through straight through cables, implementing the communication between the service processing subsystem and BAM, and the interconnection between the service processing frames. The HSCI in slot 7 is connected to LAN Switch 1, and



6-10

the HSCI in slot 9 is connected to LAN Switch 0. The connection positions of the cables on the front panels of LAN Switches are determined by the port configuration scheme.

Because the SoftX3000 adopts back cabling mode, but the network port of LAN Switch is on the front panel, the network cables from LAN Switch must be led to the cabinet back through the cabling frame under the LAN Switch. The cables must be arranged well in the cabling frame.

The network cables between service boards in the expansion frames in service processing cabinet and LAN Switches in the integrated configuration cabinet must be laid outside cabinets. For detailed information about installing and laying these cables, refer to Section 6.3.2 Modes of Laying Signal Cables.

6.4.5 Installing FE Signal Cable Between HSCI and SIUI

6.4.10 Installing Clock Cable Between Frames

I. Connecting Clock Cables

There are two types of internal clock cables: 2 MHz and 8 MHz.

Two CKII boards are connected to the active EPII board in the same frame through two 2 MHz clock cables. Figure 6-9 shows the connection of the 2 MHz clock cables.

Figure 6-9 Connection positions of 2 MHz clock cables

If more than one pair of EPII boards are configured, lead out two 2 MHz clock cables from another active EPII, and connect them to the interfaces LINE2 of the active and standby CKII boards.

The CKII board provides 16 channels of 8 kHz clock sources to other frames without clock boards through 8 kHz internal clock cables. The clock sources are connected to the EPII boards of such frames through cables, to realize the clock synchronization and hardware changeover between active and standby clock boards. Figure 6-10 shows the connection positions of 8 kHz clock cables.



6-14

Figure 6-10 Connection positions of 8 kHz clock cables

II. Laying Clock Cables

The 2 MHz synchronous clock cables are used connect the CKIIs and EPIIs in the same frame, so they are laid and bound along the cabling trough of the frame.

To lay the 8 KHz clock cables, do as follows:

1) Lay the 8 KHz clock cables of the basic frame in the integrated configuration cabinet directly into the cabling trough of the frame.

2) Separate cables to both sides of the cabinet, and lay them upward to the EPIIs in the expansion frame of the cabinet.

3) Lay the clock cables to other cabinets downward along the cabinet. 4) Lead them out of the cabinet from the bottom, and then into the other two service

cabinets from the bottom. 5) Connect them to the EPIIs in the service frames.

Figure 6-12 Connection position of trunk cable

II. Laying Trunk Cables

Before laying the trunk cables, measure the required length first. If the cables are not long enough during the actual cabling, select other proper cables instead. In special cases, splice cables for extension using dedicated coaxial cable connector, while soldering is prohibited.

In the equipment room with ESD-preventive floor, it is recommended to adopt downward cabling mode, which can ensure better appearance and easy cabling. If you use upward cabling mode, configure a cabling rack above the cabinet to lay the cables.

If you use downward cabling mode, do as follows:

1) Bend the cables at the bottom of the cabinet and reserve some surplus. Do not tighten the cables at the bottom of the cabinet when leading them out.

2) Lead them into the cabinet, and lay them along both sides of the cabinet. 3) Distribute them to the frames one by one. Other cabling positions or directions are

not allowed.

If you use upward cabling mode, do as follows:

1) Bend the cables at the top of the cabinet and reserve some surplus.



6-17

2) If cabling ladder is used, lay the cables by the side of the ladder instead of between the ladder rungs. If the distance between the cabling ladder and the cabling trough on the top of the cabinet is within 0.8 m, lay the cables directly on the cabling trough; if the distance between the cabling ladder and the cabling trough on the top of the cabinet is more than 0.8 m, use downward cabling ladder.

3) Fix the cables on the downward cabling ladder, and do not pull the cables too tight.

6.5.3 Installing Clock Cable Between SoftX3000 and BITS

I. Connecting Clock Cables

According to different signal types, the 75 ohm coaxial cables transmitting BITS clock signals are connected with the corresponding SMB connectors BITS1 and BITS2 of the CKII boards in the basic frame, as shown in Figure 6-13.

Figure 6-13 Connection of external clock cable

At the BITS device side, the connection positions are:

“ER1” and “ER2” of “2M bit/s-IN” when the synchronous signal is 2 Mbit/s signal. Two synchronous signals are required at the same time and used in active/standby mode.

“2MR1” and “2MR2” when the synchronous signal is 2 MHz signal. Two synchronous signals are required at the same time and used in active/standby mode.



6-18

II. Laying Clock Cables

To lay external clock cables, bind them together with trunk cables with the same cabling method for trunk cables.

6.5.4 Installing External Network Cables

I. Introduction to External Network Cables

The external network cables are used to connect the SoftX3000 with external network devices, and the external network ports in the SoftX3000 are provided by the corresponding back interface boards.

The media resource server (MRS) is also connected to the SoftX3000 through external networking devices. The active and standby media resource interface boards (MRIAs), media processor cards (MPCs) and shelf control cards (SCCs) are connected to the external routers or LAN Switches through the external network cables.

II. Connecting External Network Cables

The connecting positions of external network cables depend on the specific device connected with the SoftX3000. Take the connection between the SoftX3000 and IAD for example, the IAD is generally installed inside residential community or enterprise network, and it connects to the SoftX3000 through router or LAN Switch. One end of external network cable is connected to 10/100Mbit/s Ethernet ports on IFMI board in the SoftX3000, and the other end is connected with router or LAN Switch. The specific connection positions are determined by the port configuration scheme.

When the IAD is connected to the MRIA board of the SoftX3000 through external networking devices, the network cable is connected to the middle network port in the MRIA board.

III. Cabling

To lay external network cables, bind them together with trunk cables, with the same cabling method as the trunk cables.

9-5

sound in case of fault in the power distribution frame. If the switch is “OFF”, there will be no alarm sound even when there is fault occurring to the power distribution frame.

Note:

To make a full check on the monitoring function of the power distribution frame, set the MONITOR ALARM to “ON” when performing electrical check to the equipment.

9.3.3 Introduction to Power Switches in MRS

There are two power switches on the MRS chassis, located at the upper right of the front panel and marked Feed A and Feed B. They respectively correspond to –48 VDC input A and input B.

There is no independent power switch on other service frame, whose input power supply is controlled by the corresponding switch in the power distribution frame.

9.3.4 Checking Power Supply of Cabinets

The check on power supply for cabinets is to see whether there is short circuit in all output power lines from the DC power distribution frame, whether the input DC voltage to the SoftX3000 cabinets is normal and whether the visual and audible alarm function of the frames in all cabinets is normal. The check steps are described as follows:

1) Shut down the input power supply of the DC power distribution frame, set the multimeter to ohm range and check the resistance between the output power supplies and between working grounding line (GND) and protection grounding line (PGND) of the DC power distribution frame. There is no short circuit between the output power supplies.

2) Confirm that all the switches in the power distribution frame on the cabinet top are turned off, and then turn on the switch of the DC power distribution cabinet. In the case of no load, use the multimeter to check whether the output power supply is within the allowed voltage range (–57V to –40V). At this time, red “ALM” indicator on the distribution box must flash and the buzzer will give off audible alarm upon setting the ALARM switch to “ON”.

If any of the above items does not meet the requirement, find out the reason and perform troubleshooting before the next step.



9-6

9.3.5 Checking Power Supply of Frames

The check on power supply for frames is to set whether there is short circuit in all output power lines from the power distribution frame of the cabinet, and whether the input DC voltage to the intra-cabinet components is normal. The check steps are as follows:

1) Pull out all boards from the backplanes in the cabinet, and set all the switches of the distribution box on the cabinet top to position “ON”. At this time, there is no power alarm or audible alarm. The green “RUN” indicator flashes and the red “ALM” indicator does not light.

2) Check –48 VDC power supply, and the voltage, There is –48 VDC power supply to all the components, service frames and other devices, and their voltage is within the correct range (–57 V to –40 V).

If any of the above items does not meet the requirement, find out the reason and perform troubleshooting before the next step.

9.3.6 Performing Board Power-On Test

The working status of a board powered on can be known from the indicators on the board front panel. For the meanings of indicators, refer to U-SYS SoftX3000 SoftSwitch System Technical Manual Architecture and Principle.

The check steps are as follows:

1) Input and output cables of –48 VDC power supply are correctly connected and the connection cables are firm.

2) Set all the switches on power distribution frame to “OFF”. Insert the power boards in the frames, and then turn on the switches on the power distribution frame. The power boards and the fans in frames work normally.

3) Set all the switches on the power distribution frame to “OFF” once again, then insert the boards into the slots on the backplanes and fasten the front panels of the boards.

4) Set the power switches on the power distribution frame to “ON”. At this time, all board indicators are normal. If the indicators of all boards in a frame do not light after the power switches are turned on, it indicates that there is no –48 VDC input or there is connection error at the input terminals. If the power switch jumps upon being closed, it means there would be short circuit or error of connection of the output terminals (short circuit).

A.3.2 Assembling Cabling Ladder

The cabling ladder uses channel-section steel and cross stays for form its framework. .The channel-section steel functions as the vertical beams of the cabling ladder and the cross stays function as the horizontal beams. To assemble a cabling ladder, use fastener to connect the cross stays with the channel-section steel. The spacing between two cross stays is 250 mm. Because the spacing between holes in the channel-section steel is 50 mm, install one cross stay every five trough holes. When the assembled cabling ladder is used for horizontal installation, the bolt head of the cabling ladder should face downward to ensure that there is no protrusion on the ladder surface



A-9

and to facilitate the installation of cabling trough. Figure A-21 shows the basic structure of cabling ladder.

Figure A-21 Basic structure of a cabling ladder

If a longer cabling ladder is required, you can join several cabling ladders in an “end to end” fashion. The channel-section connecting piece is used to connect ladders, as shown in Figure A-22. If the length of a cabling ladder is not an integral multiple of 2.5 m, cut off the remaining part. Use brush the paint the cross section to ensure protection against corrosion and to provide aesthetic look for the ladder.

A.3.3 Connecting and Installing Cabling Troughs

Because cabling trough is cone-shaped, you can insert the smaller end of a cabling trough to the bigger end of another. The depth of inserted part is 250 mm. When



A-10

200mm-wide or 400mm-wide cabling trough is used, directly place the cabling trough on cabling ladder, and secure the cabling trough on the cabling ladder with fixing clips. For each segment of the cabling trough, four such clips are used and they should be symmetrical at both sides. Figure A-23 shows the connection of cabling troughs.

Figure A-23 Connection of cabling troughs (200mm or 400mm wide)

If a cabling trough is installed on 600mm-wide cabling ladder, it can be formed by means of joining a 200mm-wide trough and a 400mm-wide trough together with connecting clips. For each segment of cabling trough, three connecting clips are required. To install a cabling trough, secure it on cabling ladder with fixing clips. If a longer cabling trough is required, the connecting method is same as that mentioned earlier. Here, follow the principle “extended first and fixed next”. Figure A-24 shows the structure of 600mm-wide trough.

A.3.4 Installing Turning Cabling Rack

I. Connecting cabling racks on a horizontal surface

When a cabling rack has to turn perpendicularly on a horizontal surface, there are two different installation ways with regard to whether the cabling trough is adopted or not.

Cabling trough is not adopted

If the crossed cabling racks consist of only cabling ladders, use angle connecting pieces and fasteners to joint the two cabling ladders. Make sure that the two cabling ladders are on the same horizontal surface as shown in Figure A-25.

(1) Angle connecting piece

Figure A-25 Cabling ladders turning on a horizontal surface

Cabling trough is adopted

When either or both of the crossed cabling racks have cabling troughs, there must be a height difference between the two cabling racks, that is, the height of the cabling ladder of one cabling rack must be the same as the height of the cabling trough of another cabling rack, to ensure that the cables shall not encounter any trouble while turning on the cabling rack. The installation is shown in Figure A-26. In the installation, angle connecting pieces and fasteners are also used, whereas the installation method of the angle connecting pieces is different from that in as shown in Figure A-25.

(1) Angle connecting piece

Figure A-26 Cabling rack with cabling trough turning on a horizontal surface



A-12

II. Connecting cabling racks not in horizontal surface

When you want to connect cabling ladders not in a horizontal surface, use a segment of cabling ladder to make a climbing ladder. Use angle connecting pieces and fasteners to connect the cabling ladder and climbing ladder. Figure A-27 shows the vertical connection of cabling ladders, in which the left figure shows front view of the connection, and the right figure shows the side view of the connection. Pay attention to the installation of the angle connecting pieces shown in the figure. Figure A-28 shows the sloping connection of cabling ladders.

Figure A-28 Sloping connection of cabling ladders

III. Connecting cabling ladder onto wall

When the cabling rack has to be connected to the wall, use the installation method as shown in Figure A-29. The connecting components include angle connecting piece,



A-13

insulating plate, insulating washer, fastener and expansion bolt. Insulating plate and insulating washer are used to ensure insulation between the cabling rack and the wall. Meanwhile, big flat washer (φ8 of GB96-85) is used to replace the washer for the expansion bolt to increase the contact area between the washer and the insulating washer

Figure A-29 Connecting the cabling rack into the wall

A.3.5 Installing Cabling Rack in Suspension Mounting Mode or Ground Supporting Mode

You can use suspension mounting mode or ground supporting mode when cabling rack is not placed against the wall. The suspension mounting mode is similar to the ground supporting mode, except that in the former installation mode, the cabling rack is connected to the ceiling, while in the latter the cabling rack is connected to the ground. The connecting components include channel-section steels, angle connecting pieces, fasteners and expansion bolts. To install a cabling rack in suspension mounting mode or ground supporting mode, use two pieces of channel-section steels to connect the cabling ladder to the ceiling or the ground. The installation method is the same as that of connecting cabling rack to the wall.

Each piece of channel-section steel is 2.5 m long. You can cut proper length according to the heights of the cabling rack and of the equipment room. If the required length is



A-14

longer than 2.5 m, connect two pieces of channel-section steel by channel-section connecting piece with the same method as connecting cabling ladders. Meanwhile, paint the cut cross sections.

Because the spacing between the holes in the channel-section steel is 50 mm, the spacing between the suspenders or between the supporting levers must be an integral multiple of 50 mm. Otherwise, it is impossible to proceed with the installation. It is recommended that each segment of the cabling ladder is hung or supported by two sets of suspenders or supporting levers, and the spacing between two suspenders or between two supporting levers is 1250 mm .

When the suspension mounting mode or ground supporting mode is adopted, the suspenders or the supporting levers have to be installed at the outer side of the cabling ladder to facilitate the placement of cabling trough. Meanwhile, insulating plate and insulating washer must be used to ensure the insulation between the suspension components and the ceiling, or between the ground supporting components and the ground, as shown in Figure A-30.

A.3.6 Installing Triangular Support

Note:

The spacing between two triangular supports must be an integral multiple of 50 mm; otherwise, cabling ladders cannot be connected and fixed to triangular supports. A spacing of 1250 mm is recommended between two triangular supports, that is, each segment of cable ladder is supported by two triangular supports.

When cabling rack is placed against the wall, a triangular support is used to support the cabling rack. The triangular support adopts a welded structure, and it is fixed onto the wall by expansion bolts. It provides holes in its horizontal beam for installing cabling ladder. The triangular support has three specifications corresponding to the 200mm-wide, 400mm-wide, and 600mm-wide cabling ladders respectively. A larger triangular support can be used to support smaller cabling ladder, but it is not recommended here. The sizes of their installation holes in the wall are the same.

To install a triangular support, use expansion bolts to fix the support onto the wall. Use big flat washers (φ8 of GB96-85) to replace the flat washers of the expansion bolts. Meanwhile, install two insulating plates between the vertical beam of the triangular support and the wall, and install an insulating washer between the nut and the vertical beam.

To install cabling ladder onto the triangular support, place it directly on the horizontal beam of the triangular support. Align the holes on the lower side of the channel-section steel with the holes in the horizontal beam of the triangular support, and then fix them with fasteners, as shown in Figure A-31.

A.3.7 Installing Cabling Rack over Cabinet

I. Introduction to installation ways

Cabling rack can be installed over the cabinet in the following two ways (Generally, cable distribution trough is not configured on the top of cabinet for the purpose of improving system heat dissipation).

If shockproof support is installed on the cabinet, connect the cabling rack with the quake-proof support.

If no shockproof support is installed on the cabinet, connect the cabling rack with the cabinet by climbing ladder.

II. Connecting cabling rack with shockproof support

Shockproof support on the top of cabinet is welded with channel steel, and it can meet the strength requirements. It can be fixed to the two bolt holes on top of cabinet. There are bolt holes on the top plate of the shockproof support, used for fixing and bearing the cabling rack (cabling ladder). Figure A-32 and Figure A-33 show the connection method.

III. Connecting cabling rack with climbing ladder

If there is no support installed on the top of cabinet, use climbing ladder based on the size of the connecting holes provided on the top of cabinet. For specific connecting method for climbing ladder, refer to the right figure in Figure A-27 or Figure A-28.

A.3.8 Installing Accessories

I. Installing cable-through clip

Cable-through clip can be divided into two types according to whether cabling rack has cabling trough or not. Figure A-34 illustrates the case when cabling trough is not configured on cabling rack, in which, upward cable-through clip is used. When cabling trough is configured on cabling rack, downward cable-through clip is used to ensure that the upper plane of cable-through clip stays on the same level with the uppermost plane of cabling rack, and to facilitate cabling. Generally, cable-through clip is installed on the cabling ladder on the top of cabinet, and the required quantity and location depend on actual conditions of the installation site.

(1) Cable-through clip (2) Upper hole of cable-through clip (3) Lower hole of cable-through clip

Figure A-34 Installation of cable-through clip when cabling trough is not configured on cabling rack

II. Installing baffle rings

Baffle rings are directly snapped at both sides of a cabling trough. Configuring baffle rings can increase the height of a cabling trough to prevent cables from going beyond the cabling trough. Each segment of cabling trough uses four such rings and they are distributed evenly at both sides, as shown in Figure A-23.



A-19

III. Installing end covers

End covers are installed at the ends of a cabling ladder. Wherever possible, end covers must be installed to provide better appearance and prevents unintended damage to cables.

IV. Intalling cable bushings

Cable bushings are installed at the bottom edge of a cabling trough, used to prevent cables from any possible damage. Any uncovered bottom edge of cabling troughs must be installed with cable bushing. Left part in Figure A-27 shows the installation of end cover and cable bushing.

B.2.4 Printing Labels

I. Introduction to label printing

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

II. Template for printing

The Word-format template is available for label printout. You can download the template from http://tech-support.huawei.com/asp/comm/index.asp (path: //support/technical 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 must be observed:

The settings of centered characters, direction, and fonts must 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.



B-4

III. Cells merging on the template

To merge the cells, you need 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.

IV. Requirements for 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 B-3 appears before printing, click <Ignore> to continue the printing.

Figure B-3 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.



B-5

V. Requirements for 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.

VI. Requirements for printed labels

Make sure the printed labels satisfy the following requirements:

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

Contents in the cells must be aligned in the center. In a single-line printout, the dividing lines and the mark “TO” must 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.

B.2.5 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 on the labels.

For the sake of easy recognition and good looking, the font in handwriting must be close to the standard typeface as much as possible. Table B-1 shows the standard typeface.

B.2.6 Affixing Labels

I. Affixing label to signal cable

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.

The steps to affix a label to a signal cable are shown in Figure B-5, Figure B-6 and Figure B-7. The finished labels must 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 2 cm 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.

The steps to affix a label to a signal cable are as follows:

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 B-5.

B.2.7 Information Carried on Labels

I. Information 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 cabinet or power socket.

II. Information 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 B-9.

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 1Area 2 TO:

Figure B-9 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 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.

B.2.8 Remarks

The following remarks are made for attentions.

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

ink-jet printers and ink pens are forbidden for printing and writing labels. Labels must be affixed with good order in alignment.



B-10

Cable ties must 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.

B.3 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 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 is filled in.

Table B-2 shows the information on the labels of alarm box external cables.

Table B-2 Information on labels affixed to the external cables of alarm box

Content Meaning Example

MN

MN: serial number of the cabinet in the equipment room

M: The cabinet rows from front to back are numbered from A to Z.

N: The cabinet columns from left to right are numbered from 01 to 99.

For example, A01 indicates a cabinet at Row A, Column 01.

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 B-10 shows a label on the alarm cable, on which “A01” indicates that the alarm cable is connected from the first cabinet to the cabinet at Row A, Column 01 in the equipment room.

B.8 Engineering Labels for Power Cables

B.8.1 Labels for DC Power Cables

I. Introduction to the labels

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.



B-21

II. Label information meanings

Table B-9 shows the information carried on the labels for the DC power cables:

Table B-9 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 equipment 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 cabinet, 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 cabinet, while information of the local end is not necessary. Table B-9 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.

III. Label example

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 B-17.

B-22

indicates the label on the distribution cabinet side, which carries the information about the position of the cable on the equipment cabinet side.

On the equipment cabinet side, the label marked “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 at Row A, and Column 1 in the equipment room.

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

Note:

In the power distribution cabinet (or the first power cabinet of a row in the transmission equipment room), every terminal on the -48V terminal block has a numeric identification, like “08” in “A01/B08--48V2” in the above example.

PGND and BGND are copper bars, on which all the terminals are connected. In this case, it is only necessary to specify the row and column of the power distribution cabinet. For example, “A01-BGND” means that the power cable is a BGND cable that connects to the BGND copper bar of the power distribution cabinet at Row A, Column 01 in the equipment room.

B.8.2 Labels for AC Power Cables

I. Introduction to the labels

The labels are affixed to the AC cables that provide power for the cabinets, and the protection grounding cables, including the POWER, PGND, and BGND cables. The 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.

II. Label information meanings

Table B-10 shows the information carried on the labels for the AC power cables.



B-23

Table B-10 Information on labels affixed to the AC power cables

Content Meaning

C.2.2 Assembling Power Cable Connector

I. Cutting cable

To cut the cable, do as follows:

1) Place and roll the cable coils on the support, as shown in Figure C-2. 2) Measure and cut off a segment of the cable according to the cable layout of the

project design.

(1)

(1)

(1) Rolling direction

Figure C-2 Cutting a cable

II. Mounting heat-shrinkable tube

To mount heat-shrinkable tube, do as follows:

1) Cut off the power cable with an arm saw.

Because the power cable comprises many core wires, and the wire pairs are fairly fine and soft, a denticulate arm saw (with the denticulate diameter of 0.8 mm) is recommended. If available, use wire clippers (model KT35) to cut the power cable.

2) Mount the heat-shrinkable tube onto the cable from the end stripped.

III. Stripping cable

Generally, special stripping tool or electrical knife is recommended. The AM35 wire stripper is recommended for round cables.

To strip the cable, do as follows:

1) Measure the cable length to be stripped.



C-3

The stripped cable length depends on the length of the crimping sleeve behind the bare pressure terminal. For the JG bare pressure terminal commonly used by Huawei, the length of stripped cable is calculated using the formula:

L1=L2 + (2~3 mm)

where L1 is the stripped cable length and L2 the length of the effective crimping area of the JG terminal, as shown in Figure C-3.

2) Remove the multi-strand core wires at the insulation layer of the terminal end, and strand them tightly. The stranding direction should be the same as the original merging direction of the core wires.

(1)

(1) Crimping sleeve

Figure C-3 Stripping cable

Note:

When stripping cable, check with care whether the cable core wires have been seriously oxidized or corroded. If so, cut off the oxidized or corroded segment.

IV. Crimping cable

To crimp the cable, do as follows:

1) Crimp the cable with special crimping pliers or special molds. 2) Try to insert the core wires into the wire inlets of the terminal crimping sleeve until

they cannot be pushed further. Thus the core wires should protrude 2–3 mm from the terminal, as shown in Figure C-4.

3) Before crimping the wiring terminal, place the cable in the connection position so that the contact surface of the wiring terminal is parallel to the power bus. If they are not parallel, hold the end of the terminal with pliers to adjust it.

4) During crimping, use the mold with right cross section. The molding dies corresponding to the 4 types of power cables are shown in Figure C-5.

5) Ensure correct crimping position, as shown in Figure C-6.

V. Shrinking heat-shrinkable tube

As stipulated in the cable design drawings, mount the heat-shrinkable tube onto the position where the terminal and the cable are joined, and blow the tube with a heat gun until the tube shrinks and wraps up tightly, as shown in Figure C-7.

(1) Shrank heat-shrinkable tube

Figure C-7 Shrinking heat-shrinkable tube

Note:

The heat-shrinkable tube on the cable should wrap up the whole crimping sleeve of the bare pressure terminal, including the joint between the terminal and the cable.

VI. Checking cable

Table C-1 shows the normal tensile strength of the ready-made cables.

Table C-1 Tensile strength standard of ready-made cables

Cable Tensile strength

C.2.3 Application of Crimping Tool

I. Introduction to crimping tool

The crimping tools of different types are used for different purposes. The application of the crimping tool SS-325 (usually used by Huawei) for large-section power cable terminals is illustrated in Figure C-8.

(1) Fixing handle (2) Hydraulic head (3) Hand level (4) Fixing rod (5) Hydraulic switch

Figure C-8 SS325 parts

II. Using crimping tool

Note:

Improper installation of the fixed handle, the pressing and stressed components will reduce the life cycle of the crimping tool.

The steps for using crimping tool are as follows:

1) Select the crimping component as required. 2) Assemble the compressing device, bearing device and fixing handle for the

crimping tool. 3) Release the fixing handle and place the tool in right place. 4) Turn on the hydraulic switch to put the compressing device into the in-service state,

and lift the hand level. 5) Place the cable to be crimped. 6) Push down the hand level to crimp the cable. 7) Check that the cable is well crimped.

After the crimping, a black line will appear at the hydraulic switch indicating that the crimping is finished normally (as for the tool of type SS0325, there is no such a line).



C-7

Caution:

If the black line does not appear after the crimping, stop using the tool and have it repaired.

8) Turn off the hydraulic switch.

Turn off the hydraulic switch after the operation and take out the crimping components.

III. Maintenance and storage

It is required to regularly oil the crimping components, hydraulic switch and the tool body.

After using the tool, place it in a cool and ventilated place unreachable for children. Meanwhile, avoid direct sunshine.

IV. Filling and replacing oil

The oil in the tool should be replaced completely every two years, and the oil can be purchased in related authorized shop.

Caution:

Wear gloves when filling oil. Eye contact or skin contact of the oil may cause inflammation.

The oil is inedible. Put it in the place unreachable for children. In the case of eye contact, wash eyes with clean water within 15 minutes and seek

medical assistance as soon as possible. In the case of skin contact, wash the area thoroughly with clean water. Dispose it according to the requirements of the related law for environmental

protection.

The steps for filling and replace oil are as follows:

1) Turn off the hydraulic switch. 2) Screw off the fixing rod to expose the oil-embolus. 3) Put the oil-embolus upward, and screw off the oil plug. 4) Fill in oil with a little oil can. 5) After a while, tap the tool against something hard to expel the air inside it, and then

fill oil again. Repeat above steps till the pot is full.

Figure C-10 Length of stripped cable segment



C-9

Caution:

When stripping the cable, make sure that the end of the sheath is neatly stripped and the cutting angle is vertical to the cable.

For the shielded cable, avoid damaging the shield layer when stripping the protection layer. After the protection layer is stripped, fold the shielding layer backwards to the root of the cable sheath, as shown in Figure C-11.

The core wires, especially for the round communication cables, should be cut neatly. Before cutting, spread the core wires evenly apart and cut them neatly with the cutting tool, as shown in Figure C-12.

The structure and dimensions of the truncated cable should be in accordance with the requirements shown in Figure C-12. That is, the core wire should be equal to "L" in length.

(1) Folded shielding layer

Figure C-11 Folded shielded cable

Figure C-12 Bare wires of a cable

II. Inserting cable

The requirements are as follows:

The 8-core flat telephone line should be inserted from the tail of the RJ45 connector, till the point A of the connector engages the casing of power cable.

Each core wire should be inserted along the cable trough to the head of the connector, and all the core wires should be flush with the head of the connector, as shown in Figure C-13.



C-10

1) The round communication cable should be inserted into the connector in the same way as 8-core flat telephone line. The core wire end should be flush so that it is easy to be put in position.

2) The shielded cable can be inserted in the shielded RJ45 connector in the same way described above, with the folded shielding layer attaching the built-in shielding piece at the tail of the RJ45 connector and butting against point A of the connector. See Figure C-13.

III. Crimping cable

Note:

Before crimping, the RJ45 connector should be placed in the corresponding slot of the crimping pliers.

The connector should be fully crimped. After the crimping, the metal cutter should be lower than the top surface of the RJ45 connector.

When crimping an RJ45 connector onto a shielded cable, make sure that metal cutters in the connector are crimped in position and that the built-in shielding piece of the connector securely contacts the shielding layer of the cable.

After the cable is inserted in place, crimp the connector using the RJ45 crimping pliers. Figure C-16 shows a cable with an RJ45 connector.



C-13

Figure C-16 A ready-made RJ45 connector

IV. Inspecting cable

The inspection items include:

Inspect the appearances of all the connectors carefully. The connectors with shell breakage or evident crack, locking piece breakage or crack, or improper cable insertion should be discarded.

Inspect all the cables carefully. The sequence of the wires should be in line with the design requirements.

Carry out continuity check on all cables. The continuity ratio should be 100%. No short circuit should be found between cables.

Note:

For the shielded cable assembled with shielded RJ45 connector, continuity check should be performed between the shielding shell of the connector and the shielding layer of the cable.

V. Labeling

D.3 Requirements for Power Supply

D.3.1 Requirements for AC Power Supply

I. Generic requirements on AC power supply

Adopt the centralized AC power supply model of mains, uninterrupted power supply (UPS), and a reserved diesel generator.

Ensure simplicity in cable connection, security in operation, flexibility in scheduling, and convenience in maintenance.

Adopt three-phase and five-wire, or monophase three-wire AC power for low-voltage power supply system.

Table D-7 lists the nominal voltage and rated frequency of low-voltage power supply system.

Table D-7 Specifications of AC voltage and frequency

Nominal voltage Rate frequency

110/127//220/380 V 50 Hz

Adopt UPS for the backup AC power supply. Keep it the same phase with mains. Set the switching time between mains and UPS less than 10 ms; otherwise, the product will reboot or reset itself.

Ensure that the equipment runs well below nominal current; never in the threshold of failure.

Use a separate AC power supply protection unit for a piece of separate equipment. The current to trigger the protection should be greater than the

When designing the DC power supply system, consider the maximum static and dynamic load of the system. Always keep sufficient room for the two thresholds.

Choose the model of the power cables by the maximum load of power supply.

The diesel generator set of the office automatically functions in case of power failure, automatically supply when the mains is insufficient, and automatically stops functioning when power restores. It can be tested and controlled remotely in standard interface and communication protocols.

II. Power supply specifications of AC-powered equipment

Here are the power supply specifications of AC-powered equipment:




D-11

Voltage fluctuation of communications equipment: –10% – +5% of rated voltage. Voltage fluctuation of power supply equipment and important buildings:–15% –

+10% of rated voltage. Frequency fluctuation:–4% – +4%. Aberration rate of voltage sine wave: ≤5%.

III. Specifications of power cables

Here are the specifications of the power cables:

Use the neutral line of the same cross-sectional area as the live line. Select the DC power feeder on long-term load. Use fire-resistant AC cables.

D.3.2 Suggestions on AC Power Supply

When the voltage of mains power supply is not stable, use the voltage regulator in any of the following conditions:

Powered by mains, the voltage fluctuation of communications equipment exceeds the rated threshold (–10% – +5% of rated voltage).

Powered by mains, the voltage exceeds the rated voltage fluctuation of communications equipment.

Not directly powered by mains, the voltage fluctuation exceeds the rated threshold (–15% – +10% of rated voltage).

The voltage exceeds the rated AC voltage fluctuation of DC power supply equipment.

Use UPS or inverter to prevent interruption or surge of power supply. Use a diesel generator set when the mains is faulty. The capacity of the

generator set should 1.5 to 2 times of the capacity of UPS. Use two groups of storage batteries in parallel. Use one group of UPS storage batteries. The batteries can be working in parallel

or serial connection. Use main inverter based on the maximum power. Keep a backup one.

D.3.3 Requirements for DC Power Supply

Ensure stable power supply. Close the power supply equipment to the communications equipment to minimize the feeder line. The voltage level between battery and the equipment should be less than 3.2 V.

When there are more than two switching systems, use two or multiple independent power supply systems.

Set up multiple independent power supply systems for important communication centers, each of which powers a separate equipment room. For ordinary offices,




D-12

adopt the model of a centralized power supply room plus a battery room. For small-capacity offices, adopt the centralized power supply model. Always prevent the boards from the erosive chemicals given out from batteries.

Table D-8 specifies the requirements on DC power supply.

Table D-8 DC power supply specifications

Item Specifications

Voltage fluctuation of –48-V input end –40V–57V

Anti-surge current capability

Should be 1.5 times greater than the rated load current capability.

Voltage stability

When the AC input voltage range is from 85% to 110% of the rated value, and the load current is from 5% to 100% of the rated value, the output voltage of the current stabilizer is an integral value between –56.4 and –46.0V. The variance is less than equal to 1%.

Voltage surge at power-on and power-off

Less than equal to the integral value of DC output value ±5%

Peek-to-peek noise voltage ≤200mV

Dynamic response The recovery time is less than 200 ms. The exceeding amount should not be more or less than 5% of the rated DC output voltage.

D.3.4 Suggestions on DC Power Supply

Use the distributed power supply model. Scatter the power supply systems to multiple sites.

Adopt standard DC power supply system. The output voltage of the power supply equipment should meet the requirement of the communications equipment.

Enhance the reliability of the power supply system. Optimize the capacity of the storage batteries. In small-capacity offices, when it is difficult to maintain the reliability of the power supply system, expand the capacity of the storage batteries.

The total configuration of high-frequency switch rectifier should meet the load power of communication and the recharging power of the storage batteries. Adopt the redundant configuration model for the rectifier module. Use a standby rectifier for less than ten active ones; and add one rectifier for every additional ten active ones.




D-13

Equip the storage batteries in two or multiple groups. The total capacity is determined by the power feeding duration. Ensure at least one hour of power supply capability for the storage battery group.
