7750 SR-12 Overview

In This Chapter

This chapter introduces the Alcatel-Lucent 7750 SR-12 router and provides an overview of the following topics:

• Chassis Features on page 16

• 7750 SR-12 System Installation Process on page 36


Chassis Features

Chassis Features

In the 7750 SR-12 chassis, the card slots are vertically oriented. IOM slots are numbered 1 through 10. You can install a maximum of two MDAs on each IOM. You can install MDAs in either MDA slot 1 (top slot) or MDA slot 2 (bottom slot).

You can install a maximum of two SF/CPMs in the center SF/CPM slots of your 7750 SR-12 chassis, designated as slots A and B. You must install at least one SF/CPM for the router to operate. The redundant SF/CPM operates in standby mode and takes over system operation if the primary SF/CPM fails.

The 7750 SR-12 provides access to components from both the front and back sides. The filter tray, SF/CPMs, IOMs, MDAs, and IMMs are accessed from the front of the chassis. The power entry modules (PEMs) and cooling trays (impeller trays) are accessible from the chassis rear. Figure 1 and Figure 2 show the front and rear views, respectively.

DC PEMs are horizontally oriented and are accessed through the lower rear of the chassis. The top slot is number 1 and the bottom slot is number 2. You can connect DC PEMs directly to a DC power source (Figure 6). Alternatively, you can obtain power by using AC power rectifiers (Figure 7).

The mounting brackets for the chassis are factory installed to mount in a standard 19-inch wide rack. Refer to Table 2 for key descriptions of chassis features.

7750 SR-12 Overview

7750 SR-12 Modules

This section describes the 7750 SR-12 SF/CPM, IOMs, and MDAs.

• SF/CPMs on page 21

• Input/Output Modules (IOMs) on page 26

• Media Dependent Adapters (MDAs) on page 26

• Integrated Media Modules (IMMs) on page 27

SF/CPMs

The SF/CPM(s) control the routing and switching functions for the 7750 SR-12 system. The router operates with a minimum of one SF/CPM that you must install in either center slot A or B.

The SF/CPM connects directly to the backplane and carries traffic between line cards. The backplane provides high-speed access to the SF/CPMs, IOMs, and MDAs.

The switch fabric (SF) portion of the SF/CPM receives and directs traffic to the appropriate destinations according to the routing information.

Each SF/CPM module can accommodate up to three compact flash memory cards that can be used to copy and store system boot, software images, and configuration files and logs.

Note: There are three different versions of the SF/CPM module: SFM2, SFM3 and SFM4. SFM2 is referred to and labeled as SFM-400G for SR-12. But in fact it is capable of 500G switching capacity.Note: The SFM3 has improved processing capability with multi-core CPU and increased memory. The SR-12 uses the SFM3-12 with 500G switching capacity. Note: The SFM4 enables the SR systems to go to full duplex Terabit capacity (2 Terabit half duplex) to enable the platform to be fully populated with 100Gb/s linecards.

Description


7750 SR-12 Overview

SYNCHRONIZATION IN REDUNDANT SYSTEMS

The 7750 SR-12 router is capable of a 1:1 control processor module (CPM) redundancy scheme. Redundancy methods facilitate system synchronization between the active and standby CPMs so they maintain identical operational parameters to prevent inconsistencies in the event of a CPM failure.

When automatic system synchronization is enabled for an entity, any save or delete file operation configured on the primary, secondary, or tertiary locations on the active CPM file system are mirrored in the standby CPM file system.

Although software configurations and images can be copied or downloaded from remote locations, synchronization can only occur locally between compact flash drives (cf1:, cf2:, and cf3:). Synchronization can occur either:

• Automatically — Automatic synchronization is disabled by default. To enable automatic synchronization, enter the config>redundancy>synchronize command with either the boot-env parameter or config parameter.

When you specify the boot-env parameter, the BOF, boot.ldr, config, and image files are automatically synchronized. When you specify the config parameter, only the config files are automatically synchronized.

Automatic synchronization also occurs whenever the BOF is modified and when you enter an admin>save command with no filename specified.

• Manually — To execute synchronization manually, enter the admin>redundancy>synchronize command with the boot-env parameter or the config parameter.

When you specify the boot-env parameter, the BOF, boot.ldr, config, and image files are synchronized. When you specify the config parameter, only the config files are synchronized.

For more information about redundancy and synchronization, refer to the Alcatel OS System Guide.

SYNCHRONIZING REDUNDANT BITS TIMING PORTS

In 7750 SR-12 systems with redundant SF/CPMs, a Y-cable can be connected to the Building Integrated Timing Supply (BITS) port on each CPM front panel.


Chassis Features

Input/Output Modules (IOMs)

7750 SR-12 routers support a wide variety of interfaces, including Ethernet, SONET/SDH (channelized and concatenated), and ATM. Each IOM features a single-slot baseboard that can carry up to two hot-swappable MDAs with Small Form-factor Pluggable (SFP) optics, providing flexibility to mix-and-match interfaces per-slot as customer and network needs dictate.

Media Dependent Adapters (MDAs)

MDAs are supported on all platforms and provide physical interface connectivity. MDAs are available in a variety of interface and density configurations.

Chassis Components

The 7750 SR-12 chassis components are described in the following sections:

• Power Supplies on page 28

→ DC Power Entry Modules on page 29

→ AC to DC Rectifiers on page 31

• Cooling System on page 33

• Air Filter on page 34

• Impedance Panels on page 34

Power Supplies

Two slots in the chassis are designated for hot swappable, load-sharing, DC power entry modules (PEMs). There are two DC PEM types: 100-Amp single-feed PEMs and 175-Amp dual-feed PEM-3s. For more information on PEMs, see Installing DC Power Entry Modules (PEMs) on page 88.

AC power can be converted to DC power using external AC to DC rectifiers available from Alcatel-Lucent. For more information on configuring your system to use AC power, see Installing an AC Power Shelf on page 113.

POWER REDUNDANCY

You must install at least one DC PEM or PEM-3 in the 7750 SR-12 chassis. You can install an additional PEM or PEM-3 for power redundancy.

If you need to convert AC power to usable DC power and you are using 100-Amp single-feed PEMs, you can install up to two rectifiers in the same AC power shelf that you connect to your PEM. If you need to convert AC power to usable DC power and you are using 175-Amp dual-feed PEM-3s, you install four rectifiers in the AC power shelf that you connect to your PEM-3. For redundant operation, you can install a second AC power shelf. Connect the second power shelf to the second PEM or PEM-3. This ensures that the second DC PEM has an independent redundant power source.

Note: DC PEM-3s are required if you have IOM3-XPs, IOM3-XP-Bs or IMMs installed in your system.


7750 SR-12 Overview

DC POWER ENTRY MODULES

You can install and remove DC PEMs from the rear of the 7750 SR-12 chassis power slots 1 and 2. One PEM can support the full system electrical current requirements if you are operating the 7750 SR-12 without power redundancy. You must install two PEMs for redundancy. These PEMs must be powered on at all times. There are two types of PEMs: the 175-Amp PEM-3 and the 100-Amp PEM. The PEM-3 is required for the 7750 SR-12 chassis when the router has one or more IOM3-XPs, IOM3-XP-Bs, or IMMs installed. Due to increased power requirements, a 175 AMP DC PEM-3 provides dual feeds.

Figure 5 displays the 175 AMP DC PEM-3. Figure 6 displays the 100-Amp DC PEM. Table 6 provides the component descriptions for both the PEM and PEM-3.

Always operate an energized chassis with the safety cover installed over the DC power terminal block to prevent contact with hazardous voltages and currents and to prevent accidental removal.

Power cables are not included. You must order or supply power cables compliant with your local safety codes. For information about preparing cables, refer to Preparing DC-Input Power Wiring for the 100-Amp DC PEM on page 102.

There are no field replaceable parts on a DC PEM. Replace the entire unit in the event of a failure.

7750 SR-12 Overview

AC TO DC RECTIFIERS

AC to DC rectifiers change 200/240V AC power to -48 VDC power. See Figure 7 for an illustration of an AC to DC rectifier and Table 7 for descriptions of the callouts on the illustration.

Each power shelf can accommodate up to four 2500W AC to DC rectifiers that plug into a common power backplane in the AC-input power shelf. You must connect each AC power shelf to a separate PEM installed in the 7750 SR-12 chassis. For redundancy, you must install two PEMs, each connected to a separate AC to DC rectifier shelf. You must install four rectifiers in each shelf.

The AC to DC rectifiers in each power shelf provide automatic load-sharing. When a rectifier is removed, the remaining rectifiers adjust to fulfill the power requirements and maintain uninterrupted system power.

The rectifiers in the AC power shelf are hot-swappable. You can remove or replace a power module while the system is operating without affecting system operation. For maximum redundancy, connect each AC-input power module to a separate AC power source. The power source (outlet) should be located near the equipment rack and be easily accessible.

The power cord serves as a disconnect device for each rectifier. To remove power to an individual rectifier, the unit must be disconnected from the connectors.

Note: If you are using 100-Amp PEMs, your rectifier shelf will be split so that each PEM is connected to one half of the shelf. If you are using 175-Amp PEM-3s, each PEM-3 connects to a separate rectifier shelf.

7750 SR-12 Overview

Cooling System

The 7750 SR-12 system is cooled by hot-swappable impeller (fan) trays. All three impeller trays must always be installed and fully operational while the 7750 SR-12 is powered up. The trays are accessed from the rear of the chassis and are interchangeable in any tray slot.

The impellers pull air through the system from front-filtered intake vents, across the IOMs and SF/CPMs, and exhausts the air through rear vents. The impellers spin at high speed during system initialization and then slow down to normal operating speed when system initialization is complete.

The 7750 SR-12 cooling system supports two types of impeller fan trays: the Standard Fan Tray and the Enhanced Fan Tray. The 7750 SR-12 Enhanced Fan Tray offers the following improved capabilities:

• Increased air flow rate from 350 to 1000 cubic feet per minute (CFM).

• Increased level of granularity for fan speed (up to 20 speed settings) when used in conjunction with an SFM3 and software release 8.0R4 and later.

• Improved acoustical performance (69.8 dBA at 350 CFM).

• Reduced power consumption.

The 7750 SR-12 cooling system consists of the following components:

• Either (3) Standard Fan Trays or (3) Enhanced Fan Trays, each with two impellers.

• One air filter.

There are three fan tray slots in the rear of the 7750 SR-12 chassis. The left slot is designated as fan tray #1, the middle slot is designated as fan tray #2, and the right slot is designated as fan tray #3.

Note: When the chassis uses the 100 Gbps IMM, Enhanced Fan Trays are required.

Note: There are three temperature sensors per IOM and SF/CPM and one temperature sensor per MDA. The highest temperature from any sensor is reported as the temperature for that slot. With either the Standard or Enhanced Fan Tray, if the CPM LED is lit amber (indicating a fan problem), use the show card 1 detail CLI command to monitor the current temperature and temperature threshold fields. Also, on an Enhanced Fan Tray, if the fan tray front panel LED is lit red, use the show card 1 detail CLI command to monitor the current temperature and temperature threshold fields. If the temperature rises quickly and remains above the temperature threshold, an alarm is generated. Repair or replace the unit immediately if a failure occurs.


Chassis Features

The cooling system components work together to keep the internal components within the acceptable temperature range.

For the Standard Impeller Fan Tray, the status indicator LEDs are displayed on the active CPM front panel, labeled Fan Status. A green LED indicates normal operation. The LED is amber if there is an impeller failure or unlit if there is no power to a tray or a tray is not installed in the slot.

For the Enhanced Impeller Fan Tray, there are two sets of status indicators. One set is located on the active CPM front panel. A green LED indicates normal operation. The LED is amber if there is an impeller failure. It is blinking if a fan tray is not installed in the slot or if the fan temperature is too high.

The second set is located on the fan tray front panel. A green LED indicated normal operation. The LED is amber when it is safe to remove the enhanced fan tray from the chassis. The LED is red when the fan tray is starting up or to indicate a fault in the fan tray. If the LED is unlit there is no power to the fan tray.

The 7750 SR-12 chassis is shipped with three factory-installed impeller trays. You must replace the entire tray if an impeller fails.

Air Filter

The air filter prevents large particles, debris, and dust from entering and circulating through the system. Filters should be inspected monthly and replaced when indications of accumulated dust are present.The filter is factory installed and field replaceable.

Impedance Panels

Impedance panels are required in all empty card and component slots to prevent excess dust accumulation and to help control airflow and electromagnetic interference, and for safety reasons. Impedance panels include a blank board that enhances airflow and cooling. Impedance panels do not have board components or connector pins.

Cable Management System

The 7750 SR-12 chassis can accommodate two cable management trays. The trays are mounted on the front of the chassis, above and below the card slots. The cable management system manages fiber optic cables so they do not interfere with the insertion or removal of IOMs and MDAs and prevents sharp bends that can damage cable or degrade performance.

Warnings and Notes

Warnings and Notes

Warning:

• Do not assume that power has been disconnected from a circuit. Be sure to disconnect power to the equipment rack and external cables before installing or removing the 7750 SR-12 router.

• Do not install equipment that appears to be damaged.

• Install this unit in a restricted area that is only accessible by authorized service personnel.

• Do not stack any other equipment on top of the router. The chassis is not designed to support weight on top of it.


Site Preparation

Notes:

• Prepare the equipment rack and site before installing the router. Plan the router placement near the power sources and network interface connections.

• Remove paint and other nonconductive coatings from surfaces between the mounting hardware and the rack. Clean surfaces with an anti-oxidant before you install your router in the rack. The path between the chassis and the rack must be of sufficiently low impedance to facilitate the operation of any circuit overcurrent protection and it must be capable of safely conducting any fault current likely to be imposed.

• The 7750 SR-12 chassis is suitable for connection to a CBN or IBN grounding system.

• The 7750 SR-12 is intended to be located in a Central Office.

• An empty 7750 SR-12 chassis weighs approximately 124 lbs. (56.37 kg).

• Use a hand cart or mechanical lift to lift or move the router.

• Always install the heaviest equipment on the bottom of the rack to keep the center of gravity of the equipment rack as low as possible.

• To provide necessary stability, ensure that the equipment rack is bolted to the floor. Ceiling brackets are useful to provide additional stability.

• The equipment rack must be properly grounded.

• Install components after the chassis is installed in the rack.

• Maintain a clearance of at least 20 inches (50.8 cm) at the front and back of the router to ensure adequate room for component installation and service.

• Maintain a clearance of at least three inches (7.6 cm) on each side to ensure adequate air intake and exhaust.

• Maintain adequate air flow to and from all equipment in the rack, ensuring that nothing impedes with intake or exhaust air flow.

• The 7750 SR-12 router includes factory-installed rack-mounting brackets to install in a 19-inch equipment rack.

• If you have one or more IMMs installed in your router, you must install impedance panels in any slots that do not contain an IOM or IMM.

• If you have one or more IMMs installed in your router, you must use PEM-3s.

• If you are installing the 12-Port 10GB-SFP+ (IMM12-10GB-SFP+) and/or the 1-Port 100GB-CFP (IMM1-100GB-CFP), you must install Enhanced Fan Trays in your router

Calculating Maximum Power Consumption

The power consumption levels provided in Table 15 through 17 are provided for planning purposes only and do not represent actual power consumption. Your actual power consumption should always be lower than the figures shown in the tables.

The 7750 SR-12 routers have a voltage range of -40v to -72v. The lower your voltage the higher the current. This is an important factor for planning and calculating your maximum power consumption.

To calculate your maximum power consumption figure add up the wattage for each of the components installed in your system. This includes the chassis, IOMs, IMMs, SFMs, and MDAs in your system. Take the total wattage and divide by the lowest voltage threshold for your CO/POP. The result is your maximum current (amperage). See Table 23 for an example of the maximum power consumption of a system.

See Table 15 for chassis power consumption, Table 16 for MDA power consumption, and Table 17for board power consumption information.

Power consumption values are based on specific conditions, such as line rate of traffic and operating temperature of the modules. The following module conditions are used for power ratings:

• idle—Power consumption before the slot is configured or provisioned

• zero rate—0% line rate, at 25°C

• typical—50% line rate, at 25°C

• worst case—100% line rate, at 55°C

Safety Considerations


Placement

Grounding

Warning:

• Install the 7750 SR-12 chassis in standard-sized equipment racks. The 7750 SR-12 is shipped with the 19-inch rack mounting brackets installed.

• Install the 7750 SR-12 chassis in a clean, dry, ventilated, and temperature-controlled rooms.• Verify that the rack is properly bolted and braced and grounded to a grounding electrode.• Install the chassis into the equipment rack before installing components.

Warning:

• The router and equipment rack must be properly grounded. • Chassis ground cables are not included. For an AC power shelf, use only power cords that have

a grounding (earthing) path. Main grounding (earthing) connection points are through the IEC60320 appliance inlets. Grounding (earthing) points on the sides of the equipment are for equipotential bonding only and are safety grounding (earthing) points for the equipment. Lack of proper grounding (earthing) of the equipment may result in a safety hazard and excessive electromagnetic emissions.

• The grounding of the 7750 SR-12 recommended in the installation manual and the parts provided in the accessories kit is based on CSA and NEBS guidelines. Alternate ground connections may also be applicable. Ultimately, the grounding of the 7750 SR-12 shall comply with all local codes and ordinances where the 7750 SR-12 is installed.

• The ground conductor must be #2 AWG minimum. If input cables are larger than #2 AWG, use an equivalent size ground cable. Example: If a single 2/0 cable size is used for input DC power, use the same 2/0 cable size for grounding. Or, if (2) #2 AWG cables are used on inputs, use a single 2/0 size ground cable.

• Electrostatic discharge (ESD) damage can occur if components are mishandled.• Always wear an ESD-preventive wrist or ankle strap in contact with bare skin. Always connect

the ESD strap (with banana plug) to the ESD connection socket (grounding jack) on the front of the chassis.


Site Preparation

Cabling

Power

Warning:

• To comply with the GR-1089-CORE, Issue 06, requirement R4-9 [31] standard for electromagnetic compatibility and safety, all intra-building ports are specified for use with shielded and grounded cables at both ends.

• The intra-building port(s) of the equipment or sub-assembly is suitable for connection to intra-building or unexposed wiring or cabling only. The intra-building port(s) of the equipment or sub-assembly must not be metallically connected to interfaces that connect to the Outside Plant (OSP) or its wiring or to equipment in an Isolated Bonding Network (IBN) unless the wiring passes through an SPCW as defined in GR-295. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 6) and require isolation from the exposed OSP cabling. The addition of primary protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring. For equipment installed in an IBN, use Mesh-BN, Mesh-IBN, or Chain-IBN. Equipment rearrangements shall maintain the existing bonding topology.

• Bare conductors must be coated with an appropriate antioxidant compound before crimp connections are made. All unplated connectors, braided strap, and bus bars must be brought to a bright finish and then coated with an antioxidant before they are connected.

• The equipment under test (EUT) is specified for DC-I or DC-C power configurations. In the DC-C configuration, the ampacity of the conductor connecting the equipment frame to the BR conductor shall be equal to or greater than the ampacity of the associated BR conductor. The battery returns must remain isolated until they reach the main power bus.

Warning:

• Only service electrical personnel should perform wiring and cabling to the system.• All power to the equipment rack or cabinet should be disconnected before the installation.• The power cable(s) must be copper and meet your local electric code requirements.• The circuit breaker is not intended to be used as the chassis ON/OFF switch. Disconnect the

power from the power source to remove power.• The 7750 SR-12 router with DC power entry modules should be installed only in restricted

access areas (such as dedicated equipment rooms and electrical closets).



Fans

The 7750 SR-12 cooling system must have at least 3-inch clearance on the sides of the rack for proper airflow and at least 20-inches in the front and rear for installation and maintenance access.

At least two impeller trays (fan trays) must be installed before you supply power to the chassis.

Impedance panels are required in all empty card and component slots to prevent excess dust accumulation and to help control airflow and electromagnetic interference.

The Enhanced Fan Tray requires at least 3 in. of front and rear clearance for proper air intake and exhaust for systems installed inside cabinets utilizing doors, including perforated doors.

Air Filter

The air filter tray must always be installed while the 7750 SR-12 is powered up. The air filter is factory installed.

The filter should be inspected monthly and replaced when indications of accumulated dust are present.

The filter is factory-installed and is field-replaceable.

Storage

To store unused components and extra field-replaceable parts, re-wrap the components in the original packaging and keep them in a dry, dust-free temperature controlled environment.

To unload the chassis from the container:

Step 1 The container is secured by packing straps. Loosen and remove the straps to separate the box top from the bottom. Lift the box top off the pallet.

Step 2 Unfasten the brackets holding the chassis to the packing material. See Key 5 on Figure 9.

Step 3 Remove all layers of padding and packaging.

Step 4 Remove the anti-static bag from the chassis when you are ready to install the chassis into the rack.

Step 5 There are no handles or hand grips on the 7750 SR-12. Using a mechanical lift, lift the chassis from the bottom.

Step 6 For instructions on how to rack mount the chassis, see "Rack Mounting the Chassis" on page 67.



Rack Mounting the Chassis

The 7750 SR-12 router is designed for front and middle-mount installation into a 19-inch rack. The rack mounting hardware (including rack bolts) is factory installed to front-mount the chassis in a 19-inch rack. The screws that are used to attach the rack-mount brackets may be re-used if moving the brackets to the front mounting position. These screws contain a thread-locking adhesive and can be re-used approximately 5 times, depending upon the condition of the adhesive. If the condition of the adhesive is in question, additional thread-locking adhesive can be applied, at the customers discretion.

Required tools:

• Use a screwdriver to loosen and tighten the mounting bracket bolts.

Before you begin, verify:

• The equipment rack is securely installed, anchored, and grounded. Refer to the rack manufacturer’s documentation for instructions.

• Any power to the rack is OFF.

Danger:

• Only trained and qualified personnel should install or replace this chassis and chassis components.

Caution:

• There are no handles or hand grips on the 7750 SR-12. Lift the router from underneath. Do not lift the router by the internal chassis frame.

• When rack mounting the 7750 SR-12 in an equipment rack, do not stack other 7750 SR-12 units or any other equipment directly on top (where the bottom unit is supporting other devices). Each unit must be secured into the rack with the appropriate mounting apparatus.

2 Rack mounting screws

3 Rack mounting bracket



To install the chassis into the rack:

Step 1 With at least two people, or, if necessary, using a hand cart, pallet jack, or forklift, position the chassis in front of the rack.

Step 2 With one person in front of the rack and one behind the rack, lift the 7750 SR-12 from the bottom and position it in the rack.

Step 3 (Optional) Slide the chassis on top of the shelf/bar.

Step 4 Align the mounting holes on each bracket to the rack rail. Insert a screw into each hole in the mounting bracket and tighten. Do not skip any holes.


Installing the Cable Management System


The 7750 SR-12 chassis can accommodate two cable management trays. The trays are mounted horizontally on the front of the chassis, above and below the chassis card slots (card cage).

The following instructions assume that the chassis rack mounting brackets remain in the front-mounting position, as they are shipped from the factory. The cable management trays are shipped with shims screwed into the brackets. Remove the shims if the 7750 SR-12 chassis is front-mounted.

The integral cable management tray mounting brackets align with mounting holes located on each side of the chassis, above and below the card cage (Figure 11 on page 71).

If the chassis rack mounting brackets are removed and relocated to accommodate a mid-mount chassis installation, then a shim must be placed between each cable management tray mounting brackets and the chassis wall. Shims fill the gaps between the chassis wall and the cable management tray brackets that would otherwise be occupied by the rack mounting bracket (which were removed and reinstalled at the mid-line).

Key 2 on Figure 11 illustrates the cable management system installation with the chassis front mounted in an equipment rack.

Key 3 on Figure 11 illustrates the cable management system installation with the shim when the chassis is mid-mounted in an equipment rack.

The cable pegs are accessed by flipping the upper access door upward and the lower access door downward.

Mount the chassis in the equipment rack before installing the cable management trays.

The cable tray manages the cables leading from slots 2 through 9 as well as from the SF/CPM slots A and B. Cables from IOM slots 1 and 10 are not managed by this tray design. To prevent fiber damage when module ejector levers are opened and closed, cables from IOM slots 1 and 10 should be routed directly toward the outside of the chassis and into the customer-provided routing trays (FIGURE 11).



Figure 11: Cable Management System

To install cable management trays on a front rack-mounted 7750 SR-12 chassis:

Step 1 Remove the cable management trays from the packaging.

Step 2 The cable management system is shipped with the mid-mount shims attached. Loosen and remove the screws that attach the shims to the cable management system. Remove the shims. Save them for future use if necessary.

Step 3 To install the top tray, orient the tray above the card slots so the access door flips upward to access the pegs. Align the bracket holes with the mounting holes on each side of the chassis. See Key 1 on Figure 11.

Step 4 Insert a screw into each of the mounting holes on each side of the bracket and tighten. See Keys 2 and 4 on Figure 11.

Step 5 To install the bottom tray, orient the tray below the card slots so the access door flips downward to access the pegs. Align the bracket holes with the mounting holes on each side of the chassis. Insert a screw into each of the mounting holes on each side of the bracket and tighten. See Key 1 on Figure 11.

Making the Chassis Ground Connection

The 7750 SR-12 chassis must be grounded properly for all applications. Alcatel-Lucent support both CBN (common ground) and IBN (isolated ground) implementations for the chassis. Choose the size of the grounding cables according to the type of PEM used, the Agency/Country requirements of your location, and the lug sizing.

Grounding lugs are provided for the chassis ground connection. If the lugs are missing or misplaced, prepare your ground cable with a standard barrel, 2-hole lug with two 1/4-inch (.635 cm) diameter holes on a 5/8-inch (1.5875 cm) spacing. Grounding lug(s) are shipped with the chassis.

Grounding cables are not provided with the chassis. To make sure that the equipment is connected to earth ground, follow the instructions to prepare the ground wire. The length of the grounding wire depends on the location of the router and proximity to the proper grounding facilities.

Washers and screws for the grounding lugs are part of the following 7750 SR-12 Accessories Kits:

• 3HE00147BAAA (PEM1)

• 3HE00147CAAA (PEM3)

In the case of a PEM-3 upgrade, the washers and screws for the grounding lugs are part of the Accessory Kits:

• 3HE4606AAAA

• 3HE4608AAAA

Washers and screws can also be purchased as a Lug Kit: 3HE01882BAAAA.

Two grounding screws are located on the rear side of the chassis, on the top left-hand side.

Danger: Only trained and qualified personnel should install or replace this chassis and chassis components.

Note: When wiring any Alcatel-Lucent 7750 router, the ground connection must always be made first and disconnected last.



Preparing the Ground Wire

The ground conductor must be #2 AWG minimum. If input cables are larger than #2 AWG, use an equivalent size ground cable. Example: If a single 2/0 cable size is used for input DC power, use the same 2/0 cable size for grounding. Or, if (2) #2 AWG cables are used on inputs, use a single 2/0 size ground cable.

Figure 13: Preparing the Ground Wire

To prepare the ground wire:

Step 1 Using a wire-stripping tool, strip the insulation from the wire to 7/16-inches.

Step 2 Slide the open end of the ground lug (accessory box) over the exposed area of the prepared wire.

Step 3 Using a crimping tool, crimp the ground lug to the wire.

1 1 Copper wire. A single #2 AWG cable is recommended as a minimum for 175amp PEM-3 installations. An AWG #4 cable is recommended as a minimum for 100amp PEM installations.

2 Insulation stripped 7/16 in.



Making the Ground Wire Connection

The grounding studs are located on the rear side of the chassis, on the top left-hand side. Install the grounding lug, as shown in Figure 14.

The grounding of the 7750 SR-12 recommended in the installation manual and the parts provided in the accessories kit is based on CSA and NEBS guidelines. Alternate ground connections may also be applicable. Ultimately, the grounding of the 7750 SR-12 shall comply with all local codes and ordinances where the 7750 SR-12 is installed.

The NEBs certification minimum is #2 AWG. CSA Safety certification must be #2 AWG minimum. If input cables are larger than #2 AWG, use an equivalent size ground cable. Example: If a single 2/0 cable size is used for input DC power, use the same 2/0 cable size for grounding. Or, if (2) #2 AWG cables are used on inputs, use a single 2/0 size ground cable.

General Power Warnings and Notes

General Power Warnings and Notes

Danger:

• Only qualified personnel should connect power cables.

• Before working on equipment that is connected to power, remove jewelry, (rings, necklaces, watches, etc.). When metal objects are in contact with power and ground, serious burns can occur or the object can be welded to the device.

• Turn off power at the power source before you install or remove power cords.

• You must use cables which meet local electrical code requirements.

• Make your ground connections first.

Warning: The SR/ESS-12 power subsystem is based on a diode-or’d design for redundancy purposes. For this reason, a small amount of voltage (relative to ground) of approximately 3-4 volts is measured/observed on the (-) return feed, even when the branch circuit and PEM Breaker are shut off (assuming the second PEM remains powered/on). If this is a concern during the upgrade process, follow the steps below:

Step 1 Shut the branch breaker/ fuse to the redundant PEM being replaced.

Step 2 Shut the breaker off on the PEM itself.

Step 3 Pull the PEM out of its slot. This ensures no remaining voltage on the return feed.

Step 4 Remove the return cable from the PEM that has been pulled out.

By removing the PEM prior to handling the return cable, no voltage remains on the line.

Warning:


• Impedance panels are required in all empty card and component slots to prevent excess dust accumulation and to help control airflow and electromagnetic interference. Impedance panels do not have board components or connector pins.

• Electrostatic discharge (ESD) damage can occur if components are mishandled. Always wear an ESD-preventive wrist or ankle strap and always connect an ESD strap to the grounding plug on the front of the chassis.



Notes:

• The 7750 SR-12 is shipped with two factory-installed DC PEMs. Installation instructions are provided in the chapter. Removal instructions are provided in "Appendix B: Field Replaceable Units" on page 159.

• For full redundancy, each power supply module should be attached to an independent power source with a dedicated circuit breaker.

• In the event of a power unit failure (DC PEM or AC rectifier or AC power shelf), the entire power unit must be replaced. There are no field serviceable parts inside the power modules.


Installing DC Power Entry Modules (PEMs)


DC This section provides information and instructions to perform the following:

• "DC Power Warnings and Notes" on page 88

• "Installing a 175-Amp DC PEM-3" on page 91

• "Preparing Input Power Wiring for the 175-Amp PEM-3" on page 94

• "Installing a 100-Amp DC PEM" on page 100

• "Preparing DC-Input Power Wiring for the 100-Amp DC PEM" on page 102

DC Power Warnings and Notes

Special DC Wiring Notes

• The power wiring for the 100-Amp DC PEM and the 175-Amp DC PEM-3 for the SR-12/ESS-12 chassis are significantly different.

→ On the 100-Amp DC PEM, both -48VDC and RTN terminals are located on the left side, with -48VDC above the RTN.

→ On the 175-Amp PEM-3, the -48VDC and RTNs are separate and on opposite ends of the PEM. The -48VDC terminal block is located on the left side of the PEM and the RTN terminal block is on the right side.

• When you are upgrading from a 100-Amp DC PEM to a 175-Amp PEM-3, it is important to connect the RTN power lug to the right side terminal block. Connecting both the existing terminal lugs to the -48 VDC terminal block can result in arc welding (shorting) the terminal lugs to the block.

• The terminal lug spacing is the same on the 175-Amp PEM-3 and 100-Amp PEM. The terminal lugs for the PEM will fit on the terminal blocks for the PEM-3.



Notes:

• If the installer does not pay attention, the existing feeds can be physically connected (-48 VDC and -48VDC RTN) to the left side terminal block (-48 VDC) of the PEM-3 and short the -48VDC feed to the -48VDC RTN feed. The following warning label appears on the PEM-3. Remove the label after the installation.

• Follow the installation instructions Installing a 100-Amp DC PEM on page 100 and Installing a 175-Amp DC PEM-3 on page 91 making sure to follow all instructions on the labels and terminal blocks.

Danger:

• A suitable disconnect device must be provided in the DC branch, either a circuit breaker or switch that can be employed to disconnect power to the system during servicing.

• Before connecting or disconnecting ground or power wires to the chassis, ensure that power is removed from the DC circuit.

• On the PEM-3, the RTN and -48 VDC feeds are electrically joined. When power is applied to one feed, power is also present in the other feed.

• Confirm that the DC power source is OFF during installation. The power source should be a safety extra-low voltage (SELV) source.

• The 7750 SR-12 router with DC PEMs should be installed only in restricted access areas (such as dedicated equipment rooms and electrical closets) in accordance with Articles 110-26 and 110-27 of the most recent National Electrical Code ANSI/NFPA 70.



Caution:

• Make sure you directly connect the 7750 SR-12 to the DC power supply system earthing electrode conductor or to a bonding jumper from an earthing terminal bar or bus to which the DC power supply system earthing electrode is connected.

• The DC power supply source must be located within the same premises as this equipment.

• There must be no switching or disconnecting devices in the earthed circuit conductor between the DC source and the point of connection of the earthing electrode conductor.

• The 7750 SR-12 PEM-3 has a breaker rating of 175 amps. If the current drawn by your system reaches or exceeds 175 amps, the breaker trips to protect the system.

Notes:

• The remote power source (circuit breaker panel, outlet, etc.) must be easily accessible.

• Cables are not provided. In the United States, use a minimum of #4 AWG, high strand count copper wire. If the 7750 router is located outside the USA, consult local and national electrical code for proper wire sizing.

• For the DC PEM terminal block, lugs are provided. If they are missing or misplaced, use a Panduit LCC F6-14A copper, standard barrel, 2-hole lug with two 1/4-inch (.635 cm) diameter holes on a 3/4-inch (1.905 cm) spacing (0.250-20 UNC).

• Two PEM slots are located at the bottom rear of the chassis (see "7450 ESS-12 Chassis Rear View" on page 19). The slots are not labeled but for documentation purposes the top slot is referred to as slot “1” and the bottom slot is referred to as slot “2”. For full redundancy two PEMs must be installed and each PEM must be attached to an independent power source with a dedicated circuit breaker.

• The 7750 SR-12 requires a minimum of one DC PEM to operate, but two are recommended for redundancy. When two PEMs are installed, they share the electrical load equally as long as both PEMs are operational. If one PEM fails, the remaining PEM provides the power the router requires for normal operation.


• The 7750 SR-12 PEM-3 has a safety rating of 6450 watts. This rating indicates the potential output the PEM-3 can provide and the safety certification level.

Key Description

1 Slot guide

2 DC PEM

3 Captive screws (two per PEM)



To install a 175-Amp DC PEM-3:

Step 1 Remove the DC PEM-3 from the packaging.

Step 2 Make sure that the circuit breaker (ON/OFF) on the PEM-3 is in the OFF ( O ) position.

Step 3 Align a PEM-3 with a slot guide. Slide the unit into the slot until the connectors are fully seated with the receptacle in the rear of the slot.

Step 4 Secure into place by tightening the captive screws.

Step 5 Install the redundant PEM-3. Align the PEM-3 with the slot guides. Slide the unit into the slot until the connectors are fully seated with the receptacle in the rear of the slot.


Step 7 If you plan to use DC power to operate the 7750 SR-12, proceed to the following steps to connect the power cord(s).

If you plan to install AC power rectifiers to operate the 7750 SR-12, proceed to AC-Input Power Guidelines on page 111.

Step 8 Prepare the power cable terminated only with a UL-listed two-hole lug with 1/4-inch (.635 cm) holes on 3/4-inch (1.905 cm) spacing.

Step 9 Connect the VDC and RTN cables from each DC PEM-3 to separate circuit breakers.

Notes: The 7750 SR-12 PEM-3 deploys a single circuit breaker using two sets of physical studs for accommodating up to two cables or lugs. These studs are joined by a single input to the breaker on the PEM-3 unit.

There is a piece of metal under the studs that couples the two feeds. This provides flexibility for provisioning power and associated cabling. Either one or both sets of studs can be used to feed the input. The 7750 SR-12 routers have a current rating that supports a range from 90 amps up to 162 amps. You can terminate a single 160-amp circuit into either one or both of the studs, or terminate dual 80-amp feeds.

If you use dual 80 amp inputs, Alcatel-Lucent recommends that the two circuits and associated breakers be “ganged” at the head end in order to ensure that power is present or absent on both studs simultaneously in all scenarios for the PEM-3. Your actual power consumption in production will almost always be much lower than the maximum power consumption numbers published in this manual. Maximum power consumption published for the SR-12 components are measured under extreme conditions and load in order to provide a basis for planning and future growth.



The SR/ESS-12 power subsystem is a diode-or’d design for redundancy purposes. For this reason, the presence of a small amount of voltage (relative to ground) of approximately 3V to 4V will be measured/observed on the (-) return feed even when the branch circuit and PEM Breaker are shut off (assuming the second PEM remains powered/on). If a customer is concerned about this when upgrading, perform the following steps:

Step 1 Shut branch breaker/fuse to the redundant PEM being replaced.


Step 3 Pull the PEM out of its slot (this will ensure no remaining voltage on return feed).

Step 4 Remove return cable from the PEM that has been removed.

By removing the PEM prior to handling the return cable, you ensure that no voltage remains on the line.



Preparing Input Power Wiring for the 175-Amp PEM-3

PREPARING THE POWER CABLE FOR THE 175-AMP DC PEM-3

Figure 18 displays the DC terminal block stud dimensions and spacing measurements. Connect the VCD and RTN studs on the DC terminal block with power cables terminated with 0.250-20 UNC lugs (Figure 19). Use two washers sized to accommodate the 1/4 in. studs and two 0.250-20 kepnuts.

The other non-terminated end of the power cables must be prepared according to your local safety codes. The length of the power cable depends on the location of the router and proximity to the power source.

Warning:

• Ensure that all power is OFF from the DC circuit. Locate the circuit breaker on the panel board that services the DC circuit. Switch the circuit breaker to the OFF position.

• When wiring the unit, the ground connection must always be made first and disconnected last.

• The proper wiring sequence is ground/negative to ground/negative and positive/return to positive/return.

• Consult your local and national electrical codes to calculate the appropriate cable sizing.

Cabling Considerations

The 7750 SR-12 PEM-3 deploys a single circuit breaker using two sets of physical studs for accommodating up to two cables and lugs. The VDC negative (-) stud pairs are mounted on a single metal plate and are electrically joined. The return (+) stud pairs are also mounted on a single metal plate and are electrically joined. This provides flexibility for provisioning power and associated cabling. Either one or both sets of studs can be used to feed the input.

The 7750 SR-12 routers have a current rating that supports a range from 90 amps up to 162 amps. Typically you will use 4/0 cable to connect your 7750 SR-12 to the branch circuit. Terminating 4/0 cable directly to the feeds on the PEM-3 is problematic due to the thickness and bend radius limitations of the cable. Therefore, Alcatel-Lucent recommends one of the following methods to configure your cables:

• Using H-Taps to Connect Your Power Cables on page 108

• Using a Power Distribution Unit (PDU) to Connect Your Power Cables on page 109

Each of the above methods enables you to use 4/0-gauge cable at the branch circuit and #2 AWG cables to connect to the PEMs.

Make sure to adhere to all local and national safety standards and the warnings described in General Power Warnings and Notes on page 86 when cabling your power system.



USING H-TAPS TO CONNECT YOUR POWER CABLES

Figure 33: Using an H-Tap to Connect Your Power Cables

You can use H-taps to connect your power cables from the branch circuit to your 7750 SR-12 power system. See Figure 33 and follow these steps to connect your power cables using H-taps:

Step 1 At the branch circuit (key 1), connect your four 4/0 cables (key 2).

Step 2 Attach two H-taps (key 3) to each of the 4/0 cables.

Step 3 Connect one #2 AWG cable to each H-tap.

Step 4 Connect each pair of #2 AWG cables (key 4) to the feeds on the PEMs (key 5) as follows:

Connect one pair of #2 AWG cables to the two VDC negative (-) feeds on the top PEM and one pair of #2 AWG cables to the two VDC negative (-) feeds on the bottom PEM. Connect one pair of #2 AWG cables to the two return (+) feeds on the top PEM and one pair of #2 AWG cables to the two return feeds on the bottom PEM.

SR12085A



You can use a PDU to connect your power cables from the branch circuit to your 7750 SR-12 power system. See Figure 34 and follow these steps to connect your power cables using a PDU:

Step 1 At the branch circuit (key 1), connect your four 4/0 cables (key 2).

Step 2 Connect each 4/0 cable to a feed on your PDU (key 3).

Step 3 On your PDU’s power distribution connector panel, there are two feeds that correspond with each 4/0 cable (key 4). Connect two #2 AWG cables to each set of feeds that corresponds to one of the 4/0 cables.

Step 4 The connectors on your PDU are grouped into two sets of four. The connectors on the left side correspond with one PEM and the connectors on the right side correspond with the other PEM.

Connect each pair of #2 AWG cables to each pair of feeds on the PEMs (key 5) as follows:

Using the cables you have connected to the connectors on the left half of your PDU, connect one pair of #2 AWG cables to the two VDC negative (-) feeds on the top PEM and one pair of #2 AWG cables to the two return (+) feeds on the top PEM.

Using the cables you have connected to two of the four connectors on the right half of your PDU, connect one pair of #2 AWG cables to the two VDC negative (-) feeds on the bottom PEM and one pair of #2 AWG cables to the two return (+) feeds on the bottom PEM.

AC-Input Power Guidelines

This section provides information and instructions to perform the following:

• AC Power Warnings and Notes on page 111

• Installing an AC Power Shelf on page 113

• Installing the AC Power Rectifiers on page 113

• Connecting The AC Power Shelf Cables to the DC PEMs on page 114

AC

AC Power Warnings and Notes

Caution:

• Follow the manufacturer’s instructions to install AC power shelves.

• The 7750 SR-12 must be directly connected to the DC power supply system earthing electrode conductor or to a bonding jumper from an earthing terminal bar or bus to which the DC power supply system earthing electrode is connected.

• The AC power source and rectifiers that supply DC power must be located within the same premises as this equipment.

• There must be no switching or disconnecting devices in the earthed circuit conductor between the DC source and the point of connection of the earthing electrode conductor.

Warning:

• Before connecting or disconnecting ground or power wires to the AC power shelf and rectifiers, make sure that power is removed from the AC circuit.



If you intend to use AC power rectifiers to convert AC power, observe the following guidelines:

• There are no AC power cord receptacles on the 7750 SR-12 chassis. AC power must be converted to usable DC input power by connecting an external rectifier to the terminal studs on the PEM(s).

• External AC rectifiers must be able to operate with a nominal utility system voltage of 150V to 240V, or operate with input voltages ranging from 200 to 240 VAC.

• The number of AC power shelves and rectifiers depend on your configuration of IOMs and MDAs, as the cumulative power requirements can vary.

• Make sure all your cables conform to local safety codes.

• Each AC power shelf is connected directly to a DC PEM. Status is supplied through a DB-25 connection from an AC power shelf to a DC PEM.

• You must connect a grounding cable to provide a ground connection from the power shelf to the equipment rack and the 7750 SR-12 router.

For a listing of the electrical specifications for the AC-input power supply, see "Power Module Specifications" on page 41.

Notes:

• The remote power source (circuit breaker panel, outlet, etc.) must be easily accessible.

• AC power shelves and rectifiers can be ordered from Alcatel-Lucent.

• Use the cables supplied with the rectifiers. The AC power cable is non-terminated on the wall AC power-source end of the cable and must be prepared according to your local safety codes (see Figure 35 on page 114). Plugs are not provided.

• If the 7750 SR-12 router is located in the United States and cables are misplaced or lost, at the minimum use #4 American wire gauge (AWG) for the -48 and RTN power connections. Consult your local and national electrical codes to calculate the appropriate cable sizing.

• Consult your power engineering personnel to calculate the required amperage of your power cable. The cable must be able to provide power for a fully loaded 7750 SR-12 system input per NEC and local safety codes.




Installing an AC Power Shelf

The AC power shelf converts AC power from an external AC power source into DC power that is suitable for the 7750 SR-12 router. On systems using the PEM-3, a 1:1 power shelf to PEM-3 ratio exists with a maximum of two shelves and two PEMs per chassis. On systems using the PEM, a 1:2 power shelf to PEM ratio exists with one shelf and two PEMs per chassis.

If you install a power shelf that was not provided by Alcatel-Lucent, follow the manufacturer’s instructions to install AC power shelves. See Figure 35 on page 114 for an example of the installation.

AC input power, DC output power, and status are provided with cable connections from the rear of the power shelf. Individual power cables connect each AC power rectifier to the AC input power source. Each AC power shelf has DC-interconnect cables to provide DC output power (-48 DC) to the DC PEMs.

An internal fan in each rectifier circulates air from the front of the shelf, through the power module, and out through rear vents.

Installing the AC Power Rectifiers

NOTE: For normal operation, the 7750 SR-12 requires four rectifiers in an AC power shelf. Four rectifiers equally power share the load. If a rectifier fails or if power is removed to a unit, the other rectifiers power share the full load and maintain continuous system operation.

Caution: A single AC power rectifier weighs approximately 6 lbs. (2.7 kg). Use both hands when installing a rectifier.

Notes: Follow the manufacturer’s instructions to install AC power rectifiers.



Connecting The AC Power Shelf Cables to the DC PEMs

Figure 35: Connecting the Cables — 175-Amp DC PEM-3 Example

Warning:

• Make sure that power is removed from the AC circuit (power source) before handling power cables to the AC power shelf, rectifiers, and DC PEMs.

• AC power shelf cables are typically shipped non-terminated. Refer to "Preparing the Power Cable for the 100-Amp DC PEM" on page 102.

Step 9 Plug the other end of the AC input power cables into the AC power source.

Step 10 Check the LEDs on each rectifier.

Step 11 Set the power switch on each DC PEM to the ON position ( | ).

Step 12 Proceed to the next section for instructions to install the SF/CPM(s). Perform the card slot, card type, MDA, and port preconfigurations prior to installing the IOMs and MDAs. See "Installing the SF/CPM" on page 121 for instructions.


Monitoring AC Power

Monitoring AC Power

You can attach a power supply monitoring (Y-type) cable from the J10 and J11 connectors on the rear of the AC power shelf to a DB-25 connector on the DC PEM. The connection provides status such as AC power supply presence, fault reporting, and over-temperature conditions to the active CPM and lights the corresponding power supply LEDs on the CPM faceplate.

If you are using an unsplit shelf with four rectifiers, two cables will be required, one for each PEM. If you are using a split shelf with two rectifiers and one PEM, only one cable is required.

The following are the optically isolated open-collector signals:

• Fault — The unit has detected an internal fault.

• Overtemperature Warning (OTW) — The unit is overheating. Shutdown is imminent (8- second warning).

• Power Fail Warning — The output of the power unit will fail within five milliseconds.

See "Appendix C: Pinout Assignments" on page 201 for the status cable pin assignments.

Installing SF/CPM Modules


Warnings and Notes

Warning:

• Electrostatic discharge (ESD) damage can occur if IOMs, SF/CPMs, or MDAs are mishandled. Always wear an ESD-preventive wrist or ankle strap and always connect an ESD strap to the grounding plug on the front of the chassis.

• Always place router components on an anti-static surface.

• Do not power up the 7750 SR-12 until all components are installed and verified.

• Impedance panels are required in all empty card and component slots to prevent excess dust accumulation and to help control airflow and electromagnetic interference. Faceplate blanks do not have board components or connector pins.

Notes:

General:• SF/CPM modules do not require preconfiguration. Factory default values enable the system to

boot successfully.

• The 7750 SR-12 router requires at least one SF/CPM.

• Install the SF/CPM before installing any IOMs.

• Do not force an IOM into a SF/CPM slot.

• Do not force a SF/CPM into an IOM slot.

7750 SR-12:• The SR-12 card slots are vertically oriented.

• In the SR-12, SF/CPMs must be installed in the center slots labeled A and B.

• IOMs are designed to fit in slots numbered from left to right, 1 through 10.




Install the SF/CPM module before installing IOMs. Install SF/CPMs only in center slots A or B. Typically, the first SF/CPM module installed in an SR-12 chassis assumes the role as active, regardless of being inserted in Slot A or B. The next CPM installed in the same chassis then assumes the role as the standby CPM.

If you only install one CPM in your SR-12 router, it becomes the active CPM regardless of which slot it is installed in.

When the active CPM is removed for replacement or fails, the standby becomes the active CPM. If two CPMs are inserted simultaneously (or almost simultaneously) and are booting at the same time, then preference is given to the CPM installed in Slot A.

NOTE: Each SF/CPM module has two ejector levers that seat and release the card from the backplane connectors. During installation, the ejector levers must be positioned inward and then rotated outward to lock into place. The ejector levers must remain in the locked position while the card is installed in the chassis.

Figure 41: Installing the SF/CPM Module

To install an SF/CPM:

Step 1 Remove the SF/CPM module from the packaging. Do not touch the printed circuit board or connector pins.

Step 2 Remove protective cap for backplane connection.

Step 3 The SF/CPM must be installed in either chassis slot A or B.

Hold the SF/CPM by the edges and then rotate the ejector levers inward toward the faceplate.

Step 4 Align the card with the slot guides. Slide inward until the pins engage with the backplane connectors.

Step 5 Simultaneously, rotate the ejector levers outward to lock the backplane connectors and SF/CPM in place.

If an SF/CPM ejector lever does not shift to the locked position, the card is probably not seated properly in the backplane. Pull the card out halfway and then reinsert it. Shift the levers to the locked position.

Step 6 Secure the card in place by tightening the captive screws.

Step 7 (Optional) Install the redundant SF/CPM in the other center chassis slot.

Step 8 Establish a console connection on the active CPM. See "Console Connection" on page 130.

Initializing the System

The primary copy of 7750 SR OS software is located on a compact flash card that must be installed in Compact Flash Slot #3 (cf3:) in the active CPM. The removable media shipped with each software license contains a copy of the 7750 SR OS software.

Notes:

• The SF/CPM modules contain three slots for removable compact flash cards. The drives are named Compact Flash Slot #1 (cf1:), Compact Flash Slot #2 (cf2:), and Compact Flash Slot #3 (cf3:). Configurations and executable images can be stored on flash cards or an FTP file location.

• The flash card containing the bootstrap and boot option files must be installed in Compact Flash Slot #3 (cf3:) on the SF/CPM.

• You must have a console connection. See "Console Connection" on page 130 on the active CPM.


Initializing the System

Using the Compact Flash Slot #3 Locking Mechanism

NOTE: Compact Flash #3 slot has a slot locking mechanism (Figure 42) to prevent accidental jostling or removal of the flash card.

Figure 42: Compact Flash Slot #3 on the SF/CPM Front Panel

To secure a compact flash card into slot #3 in the active CPM, follow these steps:

Step 1 Loosen the compact flash slot locking screw.

Step 2 Lift the slot cover.

Step 3 Align the compact flash card with the slot guides. Insert the card until it is completely seated in the slot. Do not force the card into the slot.

Step 4 Lower the slot cover and tighten the locking screw.

SR10026A



Initial System Startup

To initialize the system, follow these steps:

Step 1 When the compact flash card is installed in the cf3: slot, the Compact Flash 3 LED on the active CPM front panel should light green within approximately 30 seconds. If it does not light or if it turns off, see "Troubleshooting".

Step 2 Press the Reset button on the active CPM or power cycle the router to initiate the boot process.

Step 3 The system searches cf3: for the boot.ldr file (also known as the bootstrap file).

Step 4 Verify the operational status by checking the Power and Status LEDs on the active CPM faceplate. If the LEDs on the front panel blink continuously, refer to "Troubleshooting" on page 127.

Step 5 After verifying the LEDs, proceed with the IOM and MDA installation and configurations.

You can either preconfigure the IOMs, MDAs, and ports prior to installation or install the IOMs and MDAs first and then configure the parameters.

To preconfigure IOMs and MDAs, see "Configuring Chassis Slot and IOM Parameters" on page 136.

TROUBLESHOOTING

If the Compact Flash 3 LED does not light after 30 seconds, the compact flash card is probably faulty. If the system cannot load or cannot find the boot.ldr file on cf3:, the Compact Flash 3 LED will turn off and the system will check for a manual boot sequence interruption. A manual boot sequence interruption is performed by connecting a terminal to a console port and hitting any key when prompted by the display. Unless an unsuccessful system initialization is manually interrupted, the system will continuously reboot in an attempt to successfully find and load the boot.ldr file. Load a compact flash card with the appropriate boot.ldr file into the cf3: slot.

When the system finds the boot.ldr file, the system processes the initialization parameters from the BOF (boot option file). The BOF should be on the same drive as the boot loader file. If the BOF cannot be found or loaded, then the system prompts for a different image and configuration location.

When the image is successfully loaded, control is passed from the boot loader file to the image. The runtime image attempts to locate the configuration file as configured in the BOF. The configuration file include chassis, IOM, MDA, and port configurations, as well as system, routing, and service configurations.


Initial System Startup

The following example displays the output when either no flash is present or the boot.ldr file cannot be found.

It is important that cables connected to the console port on the 7xx0 SR/ESS/MG products are properly terminated so as to not negatively affect the functioning of the node. Terminal servers should be properly configured so that unwanted signals from the connected device do not launch.

Noisy lines can be interpreted by the node as key strokes and could interrupt the boot sequence resulting in an outage. After reboot, the CPM can go into a continuous reboot cycle if the boot process is interrupted by random characters received on the console port.

To prevent this from happening, terminate all console connections. If a terminal server is connected to the 7xx0 CPM/CFM then ensure that it is configured to not send unwanted characters to the CPM/CFM that could interrupt the boot cycle. This could be done by configuring a 'no exec' or equivalent CLI command on the terminal server.

Establishing Router Connections


Access your newly installed router two ways:

• Console Connection on page 130

• Telnet Connection on page 132

Console Connection

To establish a console connection, you will need the following:

• An ASCII terminal or a PC running terminal emulation software set to the parameters shown in the table below.

• A standard serial cable with a female DB-9 connector.

See Table 43 for the console configuration parameter values. See Figure 44 for the locationof the console connection.

For pinout information, refer to "Appendix C: Pinout Assignments" on page 201.

Console Port



Telnet Connection

Access the router after a successful initialization with a Telnet connection from a PC or workstation connected to the network after the management port (Figure 45) has been configured using the bof>address command (see below). Telnet access provides the same options for user and administrator access as those available through the console port.

To configure the 7750 SR-12 for Telnet access, you need to have a device with Telnet software located on the same network. The SR-12 must have a management IP address. The IP address is manually configured. Each 7750 SR router is limited to a total of 7 inbound/outbound Telnet or SSH sessions to guarantee that either inbound or outbound sessions will be available. For information about configuring router parameters, refer to the 7750 SR OS Router Configuration Guide. For pinout information, refer to Appendix C: Pinout Assignments on page 201.

MAC addresses are listed on a small label on the chassis, IOM, and MDA. The MAC address also displays in the show router arp command output.

Air Filter Tray

Air Filter Tray

Notes:

• Alcatel-Lucent recommends inspecting the air filter(s) on a monthly basis. If dirt and dust accumulation are found, Alcatel-Lucent recommends replacing the air filter as the most optimal course of corrective action. If desired, customers may also clean the air filter for reuse. If cleaning the filter of a system in-service, use a spare filter as the initial replacement. Do not run the system for extended periods of time without a filter installed. The filter is made of a foam material and “dry cleaning” by use of a vacuum is recommended. After cleaning, inspect the filter to insure the filter has not been damaged prior to re-use.

Notes:

• The air filter tray is accessible from the front of the chassis.

Power Modules

This section covers:

• Removing a DC PEM on page 181

• Replacing a DC PEM on page 184

• AC Power Shelves and Rectifiers on page 187

• Disconnecting AC Power Cables from an AC Power Shelf on page 187

Warnings and Notes

Danger:

• Only trained and qualified personnel should install or replace this equipment and connect the power cables.

• Even though the power supply modules are hot swappable, for extra safety, you can turn off power at the power source and disconnect and unplug the power cables before you remove and replace a power supply module.

• You must use power cables which meet local electrical code requirements.

• If the PEM-3 LED is lit, DC power is present. Do not touch. Turn off the remote power from both power sources to the PEM before you remove the safety cover.

Warning:


• Impedance panels are required in all empty component slots to prevent excess dust accumulation and to help control airflow and electromagnetic interference. Impedance panels do not have board components or connector pins.

• The 7750 SR-12 router with DC PEMs should be installed only in restricted access areas (such as dedicated equipment rooms and electrical closets) in accordance with Articles 110-26 and 110-27 of the most recent National Electrical Code ANSI/NFPA 70.

• Electrostatic discharge (ESD) damage can occur if components are mishandled. Always wear an ESD-preventive wrist or ankle strap and always connect an ESD strap to the grounding plug on the front of the chassis.


Power Modules

Warning: The SR/ESS-12 power subsystem is based on a diode-or’d design for redundancy purposes. For this reason, a small amount of voltage (relative to ground) of approximately 3-4 volts is measured/observed on the (-) return feed, even when the branch circuit and PEM Breaker are shut off (assuming the second PEM remains powered/on). If this is a concern during the upgrade process, follow the steps below:

Step 1 Shut the branch breaker/ fuse to the redundant PEM being replaced.


Step 3 Pull the PEM out of its slot. This ensures no remaining voltage on the return feed.

Step 4 Remove the return cable from the PEM that has been pulled out.

By removing the PEM prior to handling the return cable, no voltage remains on the line.

Notes:

• The 7750 SR-12 requires a minimum of one DC PEM to operate, but two are recommended for redundancy.


• AC power rectifiers can convert AC power from an external AC power source into DC power that is suitable for the SR-12 router. AC power shelves and rectifiers are available from Alcatel-Lucent. If AC power is used, at least one AC power shelf with two rectifiers must be used.

• In the event of a PEM, AC power rectifier, or AC power shelf failure, the entire individual unit must be replaced. There are no field serviceable parts inside the components.



Removing a DC PEM

If you are operating your 7750 SR-12 with redundant DC PEMs (either PEMs or PEM-3s), you can remove and replace a single PEM without affecting your system’s operation. If you are operating your 7750 SR-12 with only one DC PEM, the system will shut down when power to the PEM is removed.

3

Figure 62: Removing a 175-Amp DC PEM-3

Danger:

• If your 7750 SR-12 router is powered by AC power rectifiers, you must remove all cable connections that attach to the DC PEM you are removing.

• If the PEM-3 LED is lit, DC power is present. Do not touch. Turn off the power from the remote power from both sources to the PEM before you remove the safety cover.

Step 6 Make sure that the VDC and RTN cables from each power supply is connected to separate circuit breakers.

Step 7 Replace the safety cover and secure into place by tightening the captive screws.

Step 8 Through the safety cover opening, set the ON/OFF switch on the PEM front panel to the ON position.

Step 9 Turn on the power at the appropriate remote source.

The SR/ESS-12 power subsystem is a diode-or’d design for redundancy purposes. For this reason, the presence of a small amount of voltage (relative to ground) of approximately 3V to 4V will be measured/observed on the (-) return feed even when the branch circuit and PEM Breaker are shut off (assuming the second PEM remains powered/on). If a customer is concerned about this when upgrading, perform the following steps:

Step 1 Shut branch breaker/fuse to the redundant PEM being replaced.


Step 3 Pull the PEM out of its slot (this will ensure no remaining voltage on return feed).

Step 4 Remove return cable from the PEM that has been removed.

By removing the PEM prior to handling the return cable, you ensure that no voltage remains on the line.



AC Power Shelves and Rectifiers

If your 7750 SR-12 router operates with redundant AC power rectifiers, you can remove and replace a unit without affecting system operation. In a system with redundant rectifiers, a single rectifier can be removed without interrupting operations as long as the other rectifier(s) are operating correctly and providing adequate power.

A rectifier is operating properly when the AC OK and DC OK LEDs are both green. A rectifier must be replaced when the Fault LED is red. Follow the manufacturer’s instructions if it is necessary to remove an AC rectifier or power shelf from the rack.

Disconnecting AC Power Cables from an AC Power Shelf

AC power shelf cables are connected directly to a DC PEM. One set of power cables (VDC and RTN) from the AC power shelf connects to a single DC PEM. A maximum of two AC power shelves can connect to a 7750 SR-12 chassis with two DC PEMs installed. When power to an AC power shelf is shut off, then power is also terminated to the DC PEM. See Figure 66 and Figure 67.

Impeller Trays

Impeller Trays

Warnings and Notes

Warning:

• Always keep your fingers away from rotating blades.

• Verify that the fan blades have stopped rotating before removing the impeller trays.

Notes:

• There are three fan tray slots in the rear of the 7750 SR-12 chassis. The left slot is designated as fan tray #1, the middle slot is designated as fan tray #2, and the right slot is designated as fan tray #3.

• Impeller trays are hot-swappable. The 7750 SR-12 chassis will operate safely while you remove and replace the trays for up to approximately 2 minutes at an ambient temperature of 104° F (35° C).

• Immediately replace the tray as soon as a failure is detected.

• In the event of a single impeller failure, the entire tray must be replaced.

• To remove and replace impeller trays you must have access to the rear of the chassis. You must have enough room, at least 20-inches, to pull the tray completely out of the slot.

Notes:

• The air filter is accessible from the rear of the chassis. Use a flathead screwdriver to loosen the captive screws.

Notes:

• Alcatel-Lucent recommends inspecting the air filter(s) on a monthly basis. If dirt and dust accumulation are found, Alcatel-Lucent recommends replacing the air filter as the most optimal course of corrective action. If desired, customers may also clean the air filter for reuse. If cleaning the filter of a system in-service, use a spare filter as the initial replacement. Do not run the system for extended periods of time without a filter installed. The filter is made of a foam material and “dry cleaning” by use of a vacuum is recommended. After cleaning, inspect the filter to insure the filter has not been damaged prior to re-use.



Impeller Tray Failure

The following sections describe how the 7750 SR-12 chassis responds to an impeller fan tray failure.

STANDARD FAN TRAY FAILURE

If a single impeller within the Standard Fan tray fails, the remaining impeller speeds up to compensate for the lost impeller. The maximum air flow decreases from 500 CFM to 410 CFM.

ENHANCED FAN TRAY FAILURE

If a single impeller within an Enhanced Fan Tray fails, the remaining impeller speeds up to compensate for the lost impeller. The maximum air flow decreases from 1000 CFM to 850 CFM.

If a single tray fails, either under the fixed-control or SFM control, the remaining fan trays speed up to compensate for the failed fan tray.


Impeller Trays

Removing an Impeller Tray

Removing an impeller tray is necessary in the event of a tray failure or to upgrade from a Standard Fan Tray to an Enhanced Fan Tray.

Once an impeller tray is removed from an operational chassis, the replacement impeller tray must be inserted into the chassis within 2 minutes (at 40°C).

SF/CPM Port Types

SF/CPM Port Types

Figure 73 displays the port types on the SF/CPM.

Figure 73: Port Types

• The Building Integrated Timing Supply (BITS) port on the SF/CPM front panel is a clock in a central office that supplies digital signal level 1 (DS1) and/or composite clock timing references to all synchronous network elements in that office. This port is provisioned with an RJ-48 connector. An appropriate T1 cable must be used to connect an asynchronous serial device to this port.

• The Console port is a Universal Asynchronous Receiver/Transmitter (UART) port used to configure router and system parameters and can be also be used for monitoring purposes. The console port is enabled by default. The default Baud rate is 115,200. This port is provisioned with an DB-9 connector. Connect the console port to a terminal with an RS-232 serial cable.

The DTE/DCE switch on the front panel controls the serial port type as either data terminal equipment (DTE) or data communications equipment (DCE).

Set the switch to DTE when connecting to the serial port of a PC with a null modem cable. Set the switch to DCE when connecting to the serial port of a PC with a straight-through cable.

The port is configured as DTE or DCE depending on the switch setting. No crossover cables are required.

• The Auxiliary port is a currently unsupported.

Notes:

• Use shielded cabling for all SF/CPM port connections.

• The Alarm port is provisioned as a DB-9 serial port and is used to connect to external alarm devices that report conditions that trigger red or amber alarms. You must provide an appropriate cable configured according to the your alarm panel.

• The Management port is a 10/100 Ethernet port which is a channel to download images and manage the system. This port is provisioned with an RJ-45 jack on the front panel. You must provide a CAT5 Ethernet cable to connect to the port.


Cable Pin Assignments


Table 52 specifies the RJ-48 timing BITS (Building Integrated Timing Supply) clock connector pinouts.

Table 53 displays the DB-9 DTE mode Console port pin assignments. Use these pin assignments when the DTE/DCE switch on the SF/CPM front panel is set to DTE.
