Product Numbers: MAS-7513CDCAGE= (Cisco 7513), MAS-7513MX-CDCAGE= (Cisco 7513-MX), MAS-7576CDCAGE= (Cisco 7576)

This publication provides the procedures to replace the card cage and backplane assembly in the Cisco 7513, Cisco 7513-MX, and Cisco 7576 routers. The card cage and backplane assembly for the Cisco 7513, Cisco 7513-MX, and Cisco 7576 chassis can be replaced in the ﬁeld. The assembly is a single ﬁeld-replaceable unit (FRU) that requires replacement by a Cisco-certiﬁed service provider only.

This publication assumes you have already performed troubleshooting on your chassis and system and determined that this replacement is required.

Product Overview

Caution Before replacing the card cage and backplane assembly, read the “Safety Guidelines”

section on page 7. The speciﬁc procedures for removing and installing the card cage and backplane assembly might require two people to perform.

Product Overview

The Cisco 7513, Cisco 7513-MX, and Cisco 7576 card cage holds the processor modules used by the system. Figure 1 shows the rear view of the system.

Thecardcageandbackplaneare one assembly.The Cisco7513 and Cisco 7513-MXinclude the card cage, backplane, dual arbiter, chassis interface, and the electrically erasable programmable read-only memory (EEPROM) devicethat contains the system MAC addresses. The dual arbiter and chassis interface are printed circuit boards that are attached to the rear of the backplane. The dual arbiter and chassis interface are replaced when the card cage and backplane assembly is replaced.

The Cisco 7576 is a dual independent router system that includes two dual arbiters, two chassis interfaces, and two EEPROM devices.

Note You must transfer the EEPROMdevice from your old card cage tothe new card cage for your

system to retain all of its MAC addresses. You must then install thenew EEPROM device on the old card cage before you return the old card cage to Cisco. This procedure only applies if you are replacing an equivalent card cage. It does not apply if you are upgrading a Cisco 7513 to a Cisco 7576.

Note The Cisco 7513, Cisco 7513-MX, and Cisco 7576 use the same chassis, power supplies,

accessories, and slot numbering scheme. The Cisco 7513 or Cisco 7513-MX chassis contains a single router that uses slot 0 though slot 12. The Cisco 7576 chassis contains two routers. Router A uses slot 0 through slot 6, androuter B usesslot 7 throughslot 12. SeeFigure 2 for an enlarged view of the Cisco 7576 interface processor slot numbering scheme. The Cisco 7513-MX backplane includes connectors for time-divisionmutliplexing (TDM)-compatible hardware.These connectors allow you to connect the Cisco 7513-MX to future TDM hardware as it becomes available.

Product Overview

Note To provide a viewable image, slot numbers 0, 1, 2, 11, and 12 are not shown in Figure 2. The

slot numbering scheme uses color coding to assist in identifying routers and CyBus assignments. Refer to the “Identifying Cisco 7576 Independent Routers and CyBuses” section in the Cisco 7500 Series Installation and ConﬁgurationGuide for detailed information on the slot numbering scheme.

Safety Guidelines

Followthese guidelines to ensure your safetyand protect the equipment. This listis not inclusiveof all potentially hazardous situations, so be alert.

Safety Guidelines

Safety with Electricity

• Never try to lift the chassis by yourself; two people are required to lift a Cisco 7513,

Cisco 7513-MX, or Cisco 7576.

• Always disconnect all power cords and interface cables before moving the chassis.

• Keep tools and chassis components away from walk areas.

• Do not work alone if potentially hazardous conditions exist.

• Do not perform any action that creates a potential hazard to people or makes the equipment

unsafe.

• Carefully examine your work area for possible hazards such as moist ﬂoors, ungrounded power

extension cables, and missing safety grounds.

Follow these basic guidelines when working with any electrical equipment:

• Before beginning any procedures requiring access to the chassis interior, locate the emergency

power-off switch for the room in which you are working.

• Disconnect all power and external cables before moving a chassis.

• Do not work alone if potentially hazardous conditions exist.

• Never assume that power is disconnected from a circuit; always check.

• Do not perform any action that creates a potential hazard to people or makes the equipment

unsafe.

• Carefully examine your work area for possible hazards such as moist ﬂoors, ungrounded power

extension cables, and missing safety grounds.

Installation Safety, ESD Precautions, and Tools Required

In addition, use the guidelines that follow when working with any equipment that is connected to telephone wiring or other network cabling:

• Never install telephone wiring during a lightning storm.

• Never install telephone jacks in wet locations unless the jack is speciﬁcally designed for wet

locations.

• Never touch uninsulated telephone wires or terminals unless the telephone line is disconnected

at the network interface.

• Use caution when installing or modifying telephone lines.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic boards or components are handled improperly, can result in complete or intermittent failures.

Following are guidelines for preventing ESD damage:

• Always use an ESD-preventive wrist strap or ankle strap and ensure that it makes good skin

contact.

• When removing or installing an ESD-sensitive component, connect the equipment end of a

ground strap to an unpainted surface of the chassis, such as the chassis frame.

• If you are returning a replaced part to the factory, immediately place it in a static shielding bag

• The wrist strap only protects the board from ESDvoltages on the body; ESD voltages on clothing

Warning For safety, periodically check the resistance value of the antistatic strap. The

measurement should be between 1 and 10 megohms.

Tools Required

You need the following tools to install or replace the backplane and card cage assembly:

• 1/4-inch ﬂat-blade screwdriver to loosen the captive screws on the power supplies and card cage

• Number 1 Phillips or 1/4-inch, ﬂat-blade screwdriver to remove any blank processor module

• Spare card cage assembly—includes the card cage with the chassis interface (attached) and dual

• ESD-preventive wrist strap

• Small piece of masking or clear cellophane tape to mark the new EEPROM device

• Antistatic packaging in which the old card cage assembly should be placed

to avoid ESD damage to the board.
