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 35

Chassis FeaturesChassis 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, and MDAs 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 5). Alternatively, you can obtain power by using AC power rectifiers (Figure 6).

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.Page 16 7750 SR-12 Installation Guide

7750 SR-12 Overview7750 SR-12 Modules

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

SF/CPMs on page 21 IOMs on page 26 MDAs on page 26 IMMs on page 26

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 two different versions of the SF/CPM module: SFM2 and SFM3. SFM2 is referred to and labeled as SFM-400G for SR-12. But in fact it is capable of 500G switching capacity.

The SFM3 has improved processing capability with multi-core CPU and increased memory. The SR-12 uses the SFM3-12 with 500G switching capacity. 7750 SR-12 Installation Guide Page 21

7750 SR-12 OverviewSYNCHRONIZATION 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. 7750 SR-12 Installation Guide Page 25

Chassis FeaturesIOMs

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.

MDAs

Alcatel-Lucents Ethernet MDAs for the Service Edge Router family provide critical high-speed interfaces. An MDA is a plug-in module that enables you to choose from fiber-optic, twisted pair, and coaxial cable. A maximum of two MDAs can be installed on each IOM. Refer to your specific MDA installation guide for LED descriptions.

IMMs

The 7750 SR Integrated Media Modules (IMMs) provide high density and high throughput in a single Ethernet line card that combines a fully distributed forwarding and packet processing services engine with physical Ethernet ports. The 7750 SR IMM delivers comprehensive IEEE 802.3 compliance and supports a broad range of copper and pluggable optical interfaces, enabling you to use many fast Ethernet, gigabit Ethernet and 10 gigabit Ethernet applications. For more information, refer to the IMM Installation Guide.Page 26 7750 SR-12 Installation Guide

7750 SR-12 OverviewChassis Components

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

Power Supplies on page 27 DC Power Entry Modules on page 28 AC to DC Rectifiers on page 30

Cooling System on page 32 Air Filter on page 33 Impedance Panels on page 33

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 77.

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 101.

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 recommended if you have IOM3-XPs or IMMs installed in your system.7750 SR-12 Installation Guide Page 27

Chassis FeaturesDC 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 or IMMs installed. Due to increased power requirements, a 175 AMP DC PEM-3 provides dual feeds.

Figure 4 displays the 175 AMP DC PEM-3. Figure 5 displays the 100-Amp DC PEM. Table 5 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 90.

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

Chassis FeaturesAC TO DC RECTIFIERS

AC to DC rectifiers change 200/240V AC power to -48 VDC power. See Figure 6 for an illustration of an AC to DC rectifier and Table 6 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.

Chassis FeaturesCooling 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.

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.

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. Page 32 7750 SR-12 Installation Guide

7750 SR-12 OverviewFor 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 or unlit if there is no power to the tray or the trays is not installed in the slot.

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.7750 SR-12 Installation Guide Page 33

Chassis FeaturesComponent Operating Requirements

Table 7 displays the 7750 SR-12 hardware component operating requirements.

1 Make sure all power cables used on the 7750 SR-12 chassis meet your local safety codes.

2 Only used for AC-to-DC power conversion.

3 Three impeller trays are recommended for normal operation. If an impeller tray failure occurs, the system can operate with two trays until a replacement is installed as long as the chassis is located in a temperature controlled area.

Warnings and NotesWarnings 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.

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. The 7750 SR-12 is intended to be located in a Central Office. An empty 7750 SR-12 chassis weighs approximately 73 lbs. (33.1122 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 that might interfere with the

normal flow of cooling air through the router. The 7750 SR-12 router includes factory-installed rack-mounting brackets to install in a

19-inch equipment rack. Page 38 7750 SR-12 Installation Guide

Site PreparationCalculating Maximum Power Consumption

The power consumption levels provided in Table 14 through 16 represent the consumption under extreme conditions (with full traffic and services and under extreme temperatures). These power consumption figures 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 20 for an example of the maximum power consumption of a system.

See Table 14 for chassis power consumption, Table 15 for MDA power consumption, and Table 16for board power consumption information.

Site PreparationSafety 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: 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 ground conductor must be #2 AWG minimum or the same AWG as the power conductors if they are larger.

The router and equipment rack must be properly grounded. 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. 7750 SR-12 Installation Guide Page 51

Safety ConsiderationsCabling

Power

Warning: To comply with the GR-1089-CORE, Issue 03, 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 4) 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 power configurations. 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).Page 52 7750 SR-12 Installation Guide

Site PreparationFans

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.

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.
