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.

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

Removing and Replacing Processor Modules
Removing and Replacing Processor Modules
Before you can replace the card cage and backplane assembly, you need to remove all processor
modules installed in the card cage, and then replace them after the new card cage assembly is in
place. The term processor module refers to the RSP2, RSP4, or RSP8 and all interface processors.
Note Always use the ejector levers when installing or removing processor modules. Amodule that
is partially seated in the backplane will cause the system to hang and subsequently crash.
Timesaver To save time when you reinstall the processor modules in the card cage and reconnect
interface cables, use the “Port and Slot Configuration Worksheet” section on page 23 to note which
cables are connected to which interface processor ports.
Timesaver Before you can remove the card cage and backplane assembly, you must remove all
processor modules and both power supplies. Plan this procedure so that you canminimize its effects
on your system.
Removing Processor Modules
To remove processor modules, follow these steps:
Step 1 Turn off power to the chassis. If two power supplies are installed, the power switch on
each supply must be in the off (O) position.
Step 2 Attach an ESD-preventive strap between you and an unpainted chassis surface.
Step 3 If there is not enough slack in the network interface cables to remove the processor
module without straining the cables, disconnect any cables attached to the interfaceports.
Step 4 You must pull each processor module straight out of its slot. Ensure that there are no
obstructions that will prevent you from doing so, such as a power strip on a rack post,
network connection devicesattached to adjacent processormodules, or extensive cabling
in front of the processor slots.
Step 5 Use a screwdriver to loosen the captive installation screws at both ends of the processor
module. (See Figure 5a.)
Step 6 Place your thumbs on the ejector levers on both ends of the processor module (see
Figure 5c) and simultaneously pull them both outward to release the processor module
from the backplane connector.
Step 7 Grasp the processor module handle with one hand and place your other hand under the
carrier to support it. Pull the processor module straight out of the slot, keeping it at a
90-degree orientation to the backplane. (See Figure 7 on page 12.)
Step 8 Place the removed processor modules in the black cardboard racks that were provided
with the original equipment packaging. (See Figure 6.) You can place all 13 processor
modules in these holders.

Caution
To prevent damage to the processor modules, do not stack them on top of each other.
Replacing Processor Modules
You can replace an interface processor in any of the 11 interface processor slots, 0 through 5, and
8 through 12, from left to right. (See Figure 1.) slot 6 and slot 7 are reserved for the RSP. Blank
processor module fillers are installed in slots without processor modules to maintain consistent
airflow through the card cage. Refer to the Cisco 7500 Series Installation and Configuration Guide
for complete information on RSP slot assignments and placement.
To replace processor modules, follow these steps:
Step 1 Turn off power to the chassis. If two power supplies are installed, the power switch on
each supply must be in the off (O) position.
Step 2 Note that processor modules are secured with two captive installation screws. Use a
number 1 Phillips or a 1/4-inch flat-blade screwdriver to loosen the two captive
installation screws and remove the processor module filler (or the existing processor
module) from the slot to be filled.
Step 3 Hold the processor module handle with one hand, and place your other hand under the
carrier to support it. (See Figure 7.) Avoid touching the board.
Step 4 Place the back of the processor module in the slot and align the carrier guides along the
sides of the processor module with the grooves in the top and bottom of the slot. (See
Figure 5a.)
Step 5 Whilekeeping the processormodule at a90-degree orientation tothe backplane, carefully
slide the processor module into the slot until the processor module faceplate makes
contact with the ejector levers.
Step 6 Using your thumbs, simultaneously push both ejector levers inward until they push the
processor module completely into the slot. Theejector levers should be in approximately
the same orientation as the processor module faceplate. (See Figure 5c.)
Cisco 7513, Cisco 7513-MX, and Cisco 7576 Card Cage and Backplane Assembly Replacement Instructions 11
Removing Power Supplies
Caution Always install blank processor module fillers in empty processor slots to maintain the
proper flow of cooling air through the chassis.
Step 7 Use a screwdriver to tighten both captive installation screws on each processor module.
Step 8 Attach network interface cables or other devices to the interface ports. Use the notes you
Step 9 After you reconnect power and turn it on, check the status of the interfaces as follows:
Figure 7 Handling a Processor Module During Installation
made in the “Port and Slot Configuration Worksheet” section on page 23.
• Enter the show interfaces [type] or show controllers [type] command to verify that
the system has acknowledged the interfaces and brought them up.
• Enter the configure command or the setup command facility to configure any new
interface(s) you might haveinstalled. This does not have to be done immediately, but
the interfaces will not be available until you configure them.
H1355a
Caution
To preventESD damage, handle processor modules by the handlesand carrier edges only.
Removing Power Supplies
Before you can replace the card cage and backplane assembly, you need to remove power supplies
(and the power supply blank, shown in Figure 10, if one is installed in a system with one power
supply), and then replace them after the new card cage assembly is in place.
To remove a power supply, follow these steps:
Step 1 Turn off (O) the system power switch on each power supply you plan to remove.

Removing the Old Card Cage and Backplane Assembly
To remove the card cage and backplane assembly, follow these steps:
Step 1 Turn the power switch on each power supply to the off position (O).
Step 2 Disconnect the power supplies.
• For DC-input power supplies, refer to the configuration note 1200-Watt DC-Input
Power Supply Replacement Instructions (Publication Number 78-1899-xx) that
shipped with your Cisco 7513,Cisco 7513-MX, or Cisco 7576 chassis equipped with
DC-input power supplies.
• For AC-input power supplies, refer to the configuration note 1200-Watt AC-Input
Power Supply Replacement Instructions (Publication Number 78-1900-xx) that
shipped with your Cisco 7513,Cisco 7513-MX, or Cisco 7576 chassis equipped with
AC-input power supplies.
Step 3 Using thedirections in the appropriate configuration note, removeeach power supply and
set it aside.
Step 4 Removeall processor modules fromthe chassis and carefully store themin antistatic bags

Step 7 When the card cage and backplane assembly is completely free of the chassis, carefully
place it on an antistatic mat or foam.
Caution The electronic components on the rearof the backplaneare completelyexposed when the
card cage and backplane assembly is removed from the chassis. To prevent damaging these
components, place the card cage and backplane assembly on an antistatic mat or foam, andplace the
assembly in the same orientation as when it is mounted in the chassis. (See Figure 11.)
This completes the procedure for removing the old card cage and backplane assembly; proceed to
the next section, “Exchanging the EEPROM Devices.”
Exchanging the EEPROM Devices
Before you install your new card cage, you must exchange the new EEPROM device(s) on the rear
of the new card cage for 00the old EEPROM device(s) on the rear of your old card cage. The
Cisco 7513 and Cisco 7513-MX include one EEPROM device and the Cisco 7576 includes two
EEPROM devices, one for router A and one for router B. The EEPROM device(s) on your old card
cage have MAC addresses programmed into them, which are necessary for your system to function
properly, and these old EEPROM device(s) are required for your system.
16 Cisco 7513, Cisco 7513-MX, and Cisco 7576 Card Cage and Backplane Assembly Replacement Instructions
Exchanging the EEPROM Devices
Caution The new EEPROM device(s) that shipped on your new card cage are blank.
Note Do not perform these steps if you are upgrading a Cisco 7513 to a Cisco 7576. These
instructions apply only to the replacement of an equivalent card cage.
The following procedure requires you to first exchange the blank EEPROM device(s) on your new
card cage for the old EEPROM device(s) from your old card cage, and then place the blank
EEPROM device(s) on your old card cage for return to Cisco. For this procedure, you need a small
piece ofmasking or cellophane tape to mark the newEEPROM device(s) as blank. The old cardcage
is assumed to have already been removed from your Cisco 7513, Cisco 7513-MX, or Cisco 7576.
To exchange the EEPROM device(s), follow these steps:
Step 1 Attach an ESD preventive wrist strap between you and an unpainted surface of the
Cisco 7513, Cisco 7513-MX, or Cisco 7576 chassis.
Step 2 Locate the blank EEPROM device(s), which are located on the rearof the newcard cage,
to the left of the chassis interface board. (See Figure 12 for the Cisco 7513 or
Cisco 7513-MX, and Figure 13 for the Cisco 7576.)
Step 3 Remove the blank EEPROM device(s) from the new card cage, place a piece of tape on
it to mark it as blank EEPROM device(s), and set it aside.
Step 4 Locate the old EEPROM device(s), which are located on the rear of your old card cage.

chassis interfaces, and two EEPROM devices. Figure 13 shows the specific location and
designation of each EEPROM device.
Step 5 Remove the old EEPROM device(s) from the old card cage, note where pin 1 is, and
immediately install them on the EEPROM socket on your newcard cage.(See Figure 12
for the Cisco 7513 or Cisco 7513-MX, and Figure 13 for the Cisco 7576.)
Step 6 Install the blank EEPROM device(s) (that you removed from your new card cage and
marked with tape) on the EEPROM socket on your old card cage; remove the small piece
of tape from the blank EEPROM device(s). Return the old card cage to Cisco.
Step 7 Repeat Step 2 through Step 6 for the second EEPROM device in the Cisco 7576.
This completes the procedure for exchanging the EEPROM device(s); proceed to the next section,
“Installing the New Card Cage and Backplane Assembly.”
Installing the New Card Cage and Backplane Assembly
To install the new card cage and backplane assembly, follow these steps:
Step 1 To install the new card cage and backplane assembly, carefully lift the assembly, place it
into the chassis opening, and slide the assembly into the chassis opening untilthe left and
right flanges on the card cage are flush with the chassis flanges. (See Figure 14.)
Step 2 Squeeze the card cage and chassis flanges together and tighten each captive screw.
(See Figure 14.) Do not overtighten the captive screws.

Step 4 Repeat Step 1 through Step 3 for the second power supply if one is installed, or Step 1
and Step 2 for the power supply blank if one is present.
Note After the AC power cable or DC powercable leads arereconnected to each power
supply, reconnect the power cable at the power source.
This completes the power supply replacement procedure.
Checking the System
To complete the installation, perform a final check of all connections, and then restart the system.
This procedure is not for new systems; perform this procedure only if you have already connected
the network interfaces and performed the first-time startup procedures discussed in the Cisco 7500
Series Installation and Configuration Guide.
To restart the system and verify that the system restarts successfully, follow these steps:
Step 1 Check the following components to make sure they are secure:
• Processor modules are fully inserted in the slots and all captive screws are tightened.
Checking the System
• Interface cable connections are secured.
• Power supplies are fully inserted in the bays, and the captive screws are tightened.
• Power supply cables are fully connected to the power supplies and the power source
and are secured with appropriate strain relief.
Step 2 Ensure that a console terminal is connected to the RSP console port and turned on, or that
you have a remote login to the router from another device through a Telnet session. (You
need to check the startup banner and displays to ensure that the system restarts properly
and that all the interfaces reinitialize in the proper state.)
Step 3 When you have checked all of the connection points, turn on the power supply in the
powerA bay by turning its power switch clockwise one-quarter turn. The OK LED on the
power supply and the power A LED on the front of the chassis should go on.
Step 4 After the power supply in bay A is on, turn the second power supply on in bay B, if one
is present for redundant power. The OK LED on each powersupply and the power A (and
B) LEDs on the front of the chassis should go on.
Note If you try to turn on a power supply and the switch resists, the power supply
probably is not fully inserted into the bay.Turn the powerswitch fully counterclockwise
(to O), loosen the captive screw, pull the power supply out of the bay about 2 inches
(5.08 cm), and then push the power supply firmly back into the slot. Do not slam the
powersupply into the slot—doing so can damage the connectors on the power supply and
the backplane. Tighten the captive screw before turning on the power switch.
Step 5 Listen for the system blower. You should hear it start operating immediately.
Step 6 On the console terminal, verify that the console displays the system banner and that the
system and all interfaces initialize successfully.
