What is the Cisco 7513?
The Cisco 7513 is a 13-slot router that supports multiprotocol, multimedia routing and bridging with
a wide variety of protocols and any combination of available electrical interfaces and media.
Network interfaces reside on interface processors that provide a direct connection between two
CyBuses in the Cisco 7513 and your external networks. The Cisco 7513 has 13 slots: interface
processor slots 0 through 5, Route Switch Processor (RSP) slots 6 and 7, and interface processor
slots 8 through 12.
There are bays for up to two AC-input or DC-input power supplies. The chassis will operate with
one power supply. While a second power supply is not required, it allows load sharing and increased
system availability. The Cisco 7513 is shown in Figure 1. The three front-panel LEDs indicate
system and power supply status, and LEDs on the RSP, interface processors, and power supplies
indicate status.

What is the Cisco 7576?
The Cisco 7576 is an independent dual router system that supports multiprotocol, multimedia
routing and bridging with a wide variety of protocols and any combination of available electrical
interfaces and media. The Cisco 7576 consists of two independent routers on a single split backplane
within the chassis footprint of a Cisco 7513 router.
Network interfaces reside on interface processors that provide a direct connection between two
independent dual CyBuses in the Cisco 7576 and your external networks. The backplane of the
Cisco 7576 has 13 slots and provides two routers on a single split backplane, designated router A
and router B. Router A uses interface processor slots 0 through 5 and a Route Switch Processor
(RSP4) in slot 6. Router B uses interface processor slots 8 through 12 and a Route Switch Processor
(RSP4) in slot 7.
There are bays for up to two AC-input or DC-input power supplies. The chassis will operate with
one power supply. While a second power supply is not required, it allows load sharing and increased
system availability.

Chassis Replacement or Upgrade Prerequisites
Safety Guidelines
The following guidelines will help to ensure your safety and protect the equipment. These guidelines
are not inclusive of all potentially hazardous situations, so be alert.
General Safety Precautions
The following are general precautions for any workplace:
•
Do not perform any action that creates a potential hazard to people or makes the equipment
unsafe.
•
•
Do not work alone when potentially hazardous conditions exist.
•
•
•
Never install equipment that appears damaged.
Do not wear loose clothing, jewelry (including rings and chains), or other items that could get
caught in the chassis. Fasten your tie or scarf and sleeves.
Keep tools and chassis components away from walk areas.
Practice good housekeeping; keep tools and parts clean, accessible, and in good working order.
Safety with Electricity
Follow these 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.
Never assume that power has been disconnected from a circuit; always check.
Carefully examine your work area for possible hazards such as moist floors, ungrounded power
extension cables, and missing safety grounds.
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 touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
•
Use caution when installing or modifying telephone lines.
Never install telephone jacks in wet locations unless the jack is specifically designed for wet
locations.
Lifting Safely
A fully configured chassis weighs approximately 160 pounds (72.6 kilograms [kg]). Before
installing the new (replacement) chassis, ensure that your site is properly prepared, so you can avoid
having to move the chassis later to accommodate power sources and network connections.
•
•
•
Never try to lift an object that is too heavy for you to lift safely by yourself.
Ensure that your footing is solid, and balance the weight of the object between your feet.
Lift the object slowly; never move suddenly or twist your body as you lift.
8 Cisco 7513 and Cisco 7576 Chassis Replacement and Upgrade Instructions
Cable Strain Relief
•
Keep your back straight and lift with your legs, not your back. If you must bend down to lift the
chassis, bend at the knees, not at the waist, to reduce the strain on your lower back muscles.
•
When lifting the chassis, grasp the underside of the chassis exterior with both hands. Do not
attempt to lift the end of the chassis with the handles on the interface processor carriers; these
handles are not designed to support the weight of the chassis.
•
Always disconnect all external cables before lifting or moving the chassis.
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. Each processor module consists
of a printed circuit board that is fixed in a metal carrier. EMI shielding, connectors, and a handle are
integral components of the carrier. Handle processor modules by the metal frame or carrier only;
avoid touching the board (particularly avoid touching any components, connector pins, or the metal
fingers on the edge connector).
Following are guidelines for preventing ESD damage:
•
•
Always use an ESD wrist strap or ankle strap and ensure that it makes good skin contact.
•
•
Place removed processor modules board-side-up on an antistatic mat or in a static shielding bag.
•
Avoid contact between the board and clothing. The ESD strap only protects the board from ESD
voltages on the body; ESD voltages on clothing can still cause damage.
When removing or installing interface processors, connect the equipment end of the ground strap
to the chassis ground screw on the interface processor end of the chassis.
If you are returning a replaced part to the factory, immediately place it in a static shielding bag
to avoid ESD damage to the board.
Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should
be between 1 and 10 megohms.
Cable Strain Relief
If possible, position the new replacement chassis close enough to the existing system so that you can
avoid having to disconnect power and interface cables. Be sure to disengage any strain relief devices
before attempting to pull the cables from the port. Following are descriptions of the different
methods of strain relief that are used on the AC-input and DC-input power cables and the various
types of network interface cables:
•
On the AC power input receptacle (on the interface processor end of the AC-input powered
chassis), a cable retention band snaps up around the plug on the power cable to prevent it from
being inadvertently pulled out of the receptacle.
•
On the DC-input power supply, use nylon cable ties to fasten the power cable to a bracket located
just to the right of the input terminal block. Carefully cut these cable ties before you disconnect
the power cable leads from the terminal block; replace the cable ties after you install the new
chassis, and wire the power cable leads to the terminal block.
•
Serial interface cables (all types) use thumbscrews on the cable connectors that secure the cable
to the Fast-Serial Interface Processor (FSIP) port.
Cisco 7513 and Cisco 7576 Chassis Replacement and Upgrade Instructions
9
Chassis Replacement or Upgrade Prerequisites
•
Ethernet interface cables use either slide-type locks or thumbscrews. Although all Ethernet
Interface Processors (EIPs) ship from the factory with slide-type locks on each port, all EIPs also
include conversion kits for replacing the slide-type locks with jackscrews to accommodate
Ethernet interface cables with thumbscrews.
•
Multimode, FDDI connectors use small plastic arms on two sides of the connector that act like
springs and are constrained by the inside of the connector port. To remove a multimode cable
from an FDDI Interface Processor (FIP) port, pinch the two plastic arms inward while pulling the
connector out of the port.
When removing any cable, pull the cable out at the connector; never pull or tug on the cable itself.
For detailed descriptions of the system components, refer to the Cisco 7500 Series Installation and
Configuration Guide.
Preparing the Work Area
Although some network downtime is unavoidable while you remove the RSPs from the old chassis,
and replace them in the new chassis, you can minimize the downtime by placing the old and new
chassis close together. If your existing chassis is mounted in a rack and there is space in the same
rack or another rack close by, we recommend that you install the new, empty chassis in the rack
before moving the components. (A fully configured chassis weighs approximately 160 pounds.)
Before installing the chassis in a new rack location, ensure that routing the interface cables to the
new positions will not strain or tangle them.
You can further minimize downtime by leaving interface cables attached when you move interface
processors to the new chassis, provided that doing so will not strain the cables.
Leave network interface cables connected to the interface ports only if the following conditions are
true:
•
You are able to place the new chassis close to the existing chassis, and moving the processor
modules to the new chassis will not strain the interface cables.
•
The new chassis is already located in its permanent location, or you will need to move it only a
few feet into the space vacated by the old chassis when it is removed.
Note If these conditions are not true, for instance, if you must remove a rack-mounted chassis
before you can install the new chassis, you must disconnect all power and network interface cables.
Ensure that your new chassis allows sufficient clearance for maintenance—to remove and replace
processor modules, the blower module, and interface cables at the interface processor end, and to
access the internal components at the noninterface processor end.
Figure 4 shows the chassis footprint and the clearance required.

Tools and Parts Required
This section lists the tools and parts you will need to complete these replacement procedures. Have
the necessary tools on hand so that you can complete the replacement without interruption:
•
To replace the chassis cover, you need a 3/16-inch, flat-blade screwdriver to loosen the captive
screws on the chassis cover panel
•
To install a replacement chassis, you need a number 1 phillips and a 3/16-inch, flat-blade
screwdriver for the captive installation screws on the processor modules (most of the carriers use
slotted screws, but some use phillips screws)
•
To install a new cable-management bracket or to move the bracket from the existing chassis, you
need the following tools and parts (pan head screws are included with the brackets):
— Number 1 phillips screwdriver
— Cable-management bracket
— Two M3 x 8-mm, phillips pan head screws
Cisco 7513 and Cisco 7576 Chassis Replacement and Upgrade Instructions
11
Replacing or Upgrading the Chassis
•
If you plan to mount or replace the chassis in an equipment rack, you also need the following
tools:
— Number 2 phillips screwdriver
— 1/4-inch and 3/16-inch, flat-blade screwdrivers
— ACS-7000RMK(=) rack-mount kit (with hardware) for the chassis (this kit also works for
the Cisco 7000 chassis)
•
Whenever you remove or install processor modules, have the following equipment on hand to
help prevent ESD damage:
— Antistatic mat or antistatic foam pad in case you need to put one of the processor modules
down
— Your own ESD-preventive strap or the disposable ESD strap that is included with all spares
Replacing or Upgrading the Chassis
The RSP is a required system component and should only be removed when the system is not
operating, although power can be on to the chassis. All interface processors support online insertion
and removal (OIR); however, after installing an interface processor, you must wait at least 15
seconds for the system to reinitialize the interfaces before installing the next interface processor.
Therefore, it is more efficient to leave the power off until all components are moved into the new
chassis, then start up the system and check the entire installation.
If you are installing the new chassis in an equipment rack, proceed to the next section. Otherwise,
proceed to the “Moving Processor Modules from the Old Chassis to the New Chassis” section on
page 18.
Replacing a Rack-Mounted Chassis
This section describes how to replace a chassis that is installed in an equipment rack. The order in
which you remove the existing system, install the new chassis, and replace the components will vary
depending upon the space available in the rack and in the work area.
Some rack configurations, such as an enclosed rack or a rack with a power strip that limits access,
prohibit the normal installation sequence of first installing the chassis in the rack and then installing
the cable-management brackets before installing the processor modules. In these situations, you can
move all the components into the new chassis before installing it in the rack, but ensure that you
follow the safety guidelines for lifting and working with electrical equipment that are provided in
the section “Safety Guidelines” beginning on page 8.
If there is sufficient space available in the same rack (or an adjacent rack) and you have a rack-mount
kit available, you can install the new (replacement) chassis before you remove the existing system.
You can minimize downtime and avoid having to disconnect network interface cables by leaving the
existing system operating while you install the empty replacement chassis in the rack. Also, an
empty chassis is significantly lighter and easier to handle than one that is fully configured. Just
ensure that both chassis, when installed, will be close enough to avoid straining the interface cables
connected to the interface processors.
If you must remove the existing system to make room for the replacement chassis, or if you need the
existing rack-mounting hardware to mount the new chassis, you will have to disconnect all network
interface cables before removing the existing system from the rack. You can leave the system
components in the old chassis until after you install the new, empty chassis in the rack.
12 Cisco 7513 and Cisco 7576 Chassis Replacement and Upgrade Instructions
Replacing a Rack-Mounted Chassis
Assess your rack and lab configuration and the equipment you have available, and then choose the
appropriate replacement procedure from the following:
•
If you have a spare rack-mount kit available and are able to install the new, empty chassis before
you shut down and remove the existing one, follow the installation instructions provided with the
rack-mount kit, Cisco 7513 and Cisco 7576 Rack-Mount Kit Installation Instructions
(Publication Number 78-2023-xx). After you install the new chassis in the rack and install the
cable-management brackets, proceed to the “Moving Processor Modules from the Old Chassis
to the New Chassis” section on page 18,” to move the components. (After you complete the
replacement and check the installation, you will be directed to the following section, “Removing
the Existing Chassis from the Rack,” to remove the empty chassis.)
•
If you must remove the existing chassis before you can install the new one, proceed to the
following section, “Removing the Existing Chassis from the Rack.”
Removing the Existing Chassis from the Rack
Before removing the existing chassis from the rack, you must shut down the system power and
disconnect the power cable and all interface cables. To help avoid problems when you install the new
chassis, label all interface cables with their slot/port address and mark the positions of the chassis
ears (with tape, chalk, or a marker) so that you can install the new chassis in the same position.
Two chassis ears hold the chassis in the rack (see Figure 5), but do not bear the weight of the chassis.
The ears are secured to the chassis sides and to the rack posts. The chassis is supported by the two
rack brackets.

We recommend that two people perform this procedure: one person should support the chassis while
the other person removes the screws that secure the ears to the rack.
Warning The chassis weighs approximately 75 pounds with just the blower module and card cage installed.
To prevent injury, have someone help you lift the chassis, as shown in Figure 6. To prevent damage to the air
intake vent below the card cage, do not lift the chassis by grasping the handle with one hand and the bottom
of the card cage with the other. Grasp the chassis as shown in Figure 6.
To remove the existing chassis from the rack, follow these steps:
Step 1
Turn off the system power and disconnect the power cable and all interface cables from
the chassis.
Step 2
Use a screwdriver to loosen and remove each of the four screws (two on each side) that

This completes the chassis removal procedure.
If you have not yet installed the new chassis in the rack, proceed to the next section.
Installing the New Chassis in the Rack
Mount the chassis in the rack before connecting any interface or power cables. If possible, install the
new, empty chassis in the rack first, and then install the system components from the old chassis. To
mount the chassis, install the ears on the chassis first, place the chassis in the rack, and then secure
the ears to the rack rails.
We recommend that two people perform this procedure. Before lifting the chassis, ensure that your
path to the rack is unobstructed.
To install the chassis in the rack, follow these steps:
Step 1
Two people are required to perform this step. With a person positioned at either side of
the chassis, grasp the bottom edge of the chassis with one hand near the front and the
handle on the side of the chassis with the other, as shown in Figure 6.
Step 2
Grasping the chassis as shown in Figure 6, slowly lift the chassis in unison. To prevent
injury, avoid sudden twists or moves.
Step 3
With the chassis positioned so the front is closest to the rack, insert the front of the chassis
into the rack between the brackets, and then slowly lower the chassis until it rests on the
two bracket ledges. (See Figure 7.)

Step 4
Slide the chassis back into the rack along the ledges until the ears meet the front mounting
posts on both sides of the rack. (See Figure 7.)
Step 5
Secure each ear to the rack-mounting post with two 10-32 x 5/8-inch, phillips pan-head
screws.
This completes the procedure for moving the chassis into the rack.
16 Cisco 7513 and Cisco 7576 Chassis Replacement and Upgrade Instructions
Installing the Cable-Management Bracket
Installing the Cable-Management Bracket
The cable-management bracket attaches to the interface processor end of the chassis just above the
card cage and below the blower module. (See Figure 8.) Use the bracket to keep network interface
cables untangled and orderly, and to prevent cables from hindering access to interface processors in
the interface processor slots.
Install the bracket before connecting network interface cables to the interface processor ports;
otherwise, you will probably need to disconnect the cables to install the screws that secure the
brackets. Route interface cables through the bracket as you connect them to the interface processor
ports.
Tools and Equipment Required
You will need the following tools and parts to install the cable-management brackets; brackets and
pan head screws are included with the chassis:
•
•
Large flat-blade screwdriver
One cable-management bracket and two slotted pan head screws (already attached to the chassis)
Installation Procedure
To install the cable-management bracket on the router, follow these steps:
Step 1
Figure 8
On the interface processor end of the chassis, locate the two slotted screws positioned
below the blower module and above the card cage. (See Figure 8.)

Step 2
Use a flat-blade screwdriver to loosen the two slotted screws approximately 1/8-inch.
Step 3
Place the bracket over the screws (see Figure 8), and slide the bracket to the right.
Step 4
Use a flat-blade screwdriver to tighten the screws.
Step 5
When installing the network interface cables, route the cables up to and through the
cable-management bracket.
Route the excess cable out through either end of the bracket, coil it, and secure it to the
rack using nylon cable ties, or some other mode of attachment.
It might be necessary to bundle longer cables to avoid tangling them. Do this at the
cable-management bracket or at the rack, but leave enough slack in the cables to remove
processor modules. Change cables as required. Also, do not block the power supply air
vents with cables.
This completes the procedure for installing the cable-management bracket.
Moving Processor Modules from the Old Chassis to the New Chassis
At the interface processor end of the chassis, slots contain the processor modules. (See Figure 1.) In
the Cisco 7513, the RSP occupies RSP slot 6 or 7. In the Cisco 7576, the RSP placed in slot 6
controls router A and the RSP in slot 7 controls router B. The remaining 11 slots support any
combination of interface processors.
Note If you are upgrading a Cisco 7513 to a Cisco 7576, you need to carefully consider how you
will transfer the existing RSP(s) and interface processors from the Cisco 7513 to the Cisco 7576. For
example, if the existing Cisco 7513 includes two RSPs utilizing the “High System Availability”
(HSA) feature, keep in mind that this configuration is not supported in the Cisco 7576. Refer to the
“Port and Slot Configuration Worksheet” on page 28 for port and slot planning assistance. In
addition, the Cisco 7500 Series Installation and Configuration Guide includes detailed information
on Cisco 7576 RSP and interface processor port assignments and usage.
Processor modules are keyed with guides on the backplane to prevent them from being fully inserted
in the wrong slot. Empty interface processor slots contain an interface processor filler (an empty
carrier) to help keep dust out of the chassis, provide electromagnetic interference (EMI) shielding,
and maintain proper air flow through the chassis interior.
Processor modules slide into the processor slots and connect directly to the backplane. The
spring-loaded ejector levers (see Figure 9) help to ensure that the bus connector on the back of the
processor module is fully seated in the backplane or fully dislodged from it. Captive installation
screws at both ends of each processor module faceplate prevent the processor from pulling away
from the backplane and support the EMI integrity of the system. Failure to use the ejector levers and
captive installation screws could result in a partial backplane connection, which can hang the system.
If you are replacing a Cisco 7513 chassis, move the interface processors to the same slot positions
in the new chassis to retain your existing configuration. When upgrading a Cisco 7513 to a Cisco
7576, it is not possible to retain the existing configuration. The lithium battery backup on the RSP
retains the system configuration in nonvolatile random-access memory (NVRAM). Therefore, if you
install interface processors in the same slot positions in the new chassis that they occupied in the old
chassis, the system and the individual interfaces should come up in their previous configuration. If
you install interface processors in different slots in the new chassis, the system will recognize the
interfaces, but will leave them in a shutdown state until you reconfigure and enable them.
18 Cisco 7513 and Cisco 7576 Chassis Replacement and Upgrade Instructions
Moving Processor Modules from the Old Chassis to the New Chassis
Note We recommend that you refer to the “Port and Slot Configuration Worksheet” section on
page 28 before you remove interface processors from the old chassis. This will ensure that you
install them in the correct slots in the new chassis based on the configuration stored in NVRAM on
the RSP.
Although interface processors support OIR, you must wait at least 15 seconds after inserting an
interface processor before inserting the next one. To help avoid errors with the installation, leave the
power off until you have moved all components into the new chassis and have verified that all of
them are installed properly.
Move the interface processors first, one at a time, then move the RSPs last. Before you remove an
interface processor from the existing chassis, remove the interface processor filler from the
corresponding slot in the new chassis. Then immediately install the interface processor in the new
chassis and secure it in the slot before removing the next interface processor filler or module. If you
leave the interface cables attached to the interface processors, route the cables through the
cable-management brackets immediately after you secure the interface processor in the slot to help
keep the other slots clear during the installation.
If there is sufficient slack in the interface cables, and if you can easily move the processor modules
between the chassis without straining the cables, leave the interface cables connected. If you must
disconnect the cables, label each cable with its slot and port number before you disconnect it. Do not
reconnect the interface cables until you have installed all of the components in the new chassis (it is
easier to install interface processors when the slots are not impeded by cables that drop from other
slots). Use the optional cable-management brackets to keep the interface cables untangled and away
from other interface processor slots and ports.
Note The Cisco 7513 and Cisco 7576 allow you to remove and replace interface processors and
RSPs while the system is powered on; however, you must shut down the system power before
accessing the chassis interior for any other reason. If you intend to remove and replace an interface
processor or RSP while the system is powered on, do so only when no operations are taking place
that involve the RSPs NVRAM or flash memory. This includes operations involving system
configuration changes, and downloading microcode images.

Moving Processor Modules from the Old Chassis to the New Chassis
To move the processor modules to the new chassis, follow these steps:
Step 1
Before moving any processor modules, ensure that you have met the following
prerequisites (refer to the “What is the Cisco 7513?” section on page 2” or the “What is
the Cisco 7576?” section on page 3 for details):
•
On both chassis, ensure that the power is turned off and the power cable is
disconnected from the AC power receptacle or the DC terminal block.
•
To prevent ESD damage, wear a grounding strap or other ESD-prevention device and
attach the equipment end to the chassis ground screw on the interface processor end
of the chassis. (See Figure 1.)
•
If you will leave the interface cables connected to the processor modules, ensure that
there is sufficient slack to avoid straining the cables when moving the processor
module between chassis. Otherwise, label each cable with its slot and port number
position. (This will help avoid mixing up cables when you reconnect them.)
•
Optional: Install the cable-management brackets on the new chassis before moving
the components. Either move the brackets from the old chassis or install a new set.
Step 2
Note the slot location of the interface processor you are going to move. Before removing
the interface processor, remove the interface processor filler from the corresponding slot
in the new chassis. When installing interface processors in the new chassis, place them in
the same slot position that they occupied in the old chassis; this will retain your existing
configuration and will help avoid confusion when reconnecting cables and checking the
installation.
Step 3
If necessary, disconnect any interface cables that are connected to the processor module.
Step 4
Use a screwdriver to loosen both captive installation screws on the processor module.
(See Figure 9a.)
Step 5
Place your thumbs on the end of each ejector and simultaneously pull both ejectors
outward, away from the carrier handle (in the opposite direction from that shown in
Figure 9c) to release the processor module from the backplane.
Caution You must install the RSP in one of the slots labeled RSP (slot 6 or 7). We recommend that you place
the RSP in the same slot in the new chassis that it occupied in the old one. You can install interface processors
in any of the interface processor slots (the lowest slots), but we recommend that you install them in the same
slot positions that they occupied in the old chassis. The slots are keyed for correct installation. Forcing a
processor module into the wrong slot can damage the backplane and board connectors.
Note If you are upgrading a Cisco 7513 to a Cisco 7576, you need to carefully consider how you
will transfer the existing RSP(s) and interface processors from the Cisco 7513 to the Cisco 7576. For
example, if the existing Cisco 7513 includes two RSPs utilizing the HSA feature, keep in mind that
this configuration is not supported in the Cisco 7576. Refer to the “Port and Slot Configuration
Worksheet” section on page 28 for port and slot planning assistance. In addition, the Cisco 7500
Series Installation and Configuration Guide includes detailed information on Cisco 7576 RSP and
interface processor port assignments and usage.
Step 6
Grasp the processor module handle with one hand and pull the processor module straight
out of the slot, keeping your other hand under the carrier to guide it. (See Figure 10.) Keep
the carrier at a 90-degree orientation to the backplane. Avoid touching the board or any
connector pins.
Cisco 7513 and Cisco 7576 Chassis Replacement and Upgrade Instructions
21
Replacing or Upgrading the Chassis
Step 7
Place the processor module in the same slot position in the new chassis and align the
notches along the edge of the carrier with the grooves in the slot. (See Figure 9a.)
Step 8
While keeping the carrier at a 90-degree orientation to the backplane, carefully slide the
carrier into the slot until the back of the faceplate makes contact with the ejector levers,
and then stop. (See Figure 9b.)
Do not use unnecessary force when installing processor modules. Always guide the
carrier into the slot only until the carrier faceplate makes contact with the ejector levers;
then use the ejector levers to complete the insertion.
Step 9
Using the thumb and forefinger of each hand to pinch each ejector, simultaneously push
both ejectors inward (toward the carrier handle) until they snap into place and are at a full
90-degree orientation to the faceplate. (See Figure 9c.) The carrier ears (the ends of the
faceplate) should be flush against the chassis.
Step 10
Use a screwdriver to tighten the two captive screws to prevent the processor module from
becoming partially dislodged from the backplane and to ensure proper EMI shielding.
Step 11
Repeat Steps 2 through 10 for the remaining interface processors.
Handling a Processor Module
H1355a
Figure 10
Note Leave the interface processor filler installed in any unfilled interface processor slots.
This completes the processor module removal and replacement procedure. If you need to install the
new chassis in an equipment rack, proceed to the “Installing the New Chassis in the Rack” section
on page 15. Otherwise, proceed to the next section to check the installation.
22 Cisco 7513 and Cisco 7576 Chassis Replacement and Upgrade Instructions
Checking the Installation
Checking the Installation
To complete the replacement procedure, perform the following steps to verify that the system is
functioning properly. These steps will also help you verify that all the processor modules you moved
are returned to their previous state. For additional first-time startup troubleshooting procedures, refer
to the Cisco 7500 Series Installation and Configuration Guide.
Because the lithium battery backup on the RSP retains the system configuration in NVRAM, the
system and the individual interfaces should come up in their previous configuration, provided that
you installed the interface processors in the same slots they occupied in the old chassis.
If, however, you installed interface processors in different slot positions in the new chassis, the
system will recognize the interfaces, but will leave them in a down state until you reconfigure and
enable them.
If you need technical assistance, refer to the “Cisco Connection Online” section on page 29.
Step 1
Ensure that the system power switch is off, and then reconnect the power cable to the AC
receptacle or DC terminal block, as required. For the AC-input power supply, snap the
cable retention clip up around the plug to secure the cable. For the DC-input power
supply, reattach a new nylon cable tie to support the weight of the cable.
Step 2
Connect all interface cables to the appropriate interface processor ports. Ensure that all
cables are fully seated in the ports and that all strain relief systems are engaged.
Step 3
Ensure that you have either a console terminal connected to the system console port or a
port available for a Telnet session to the router.
Step 4
Turn on the system power. On the power supplies, the (AC or DC) OK LED should go on
and stay on. (See Figure 11.)

Replacing or Upgrading the Chassis
If the system does not go on, check the following: If the system goes on, go to step 5.
Step 5
Step 6
•
Check the source power. Ensure that the power switch is completely in the On (|)
position and that the power (input) cord is properly connected at both ends.
•
Check the fan OK LED. When on, this LED indicates the blower is operating. If the
(AC or DC) OK LED is off and the blower is not operating, there is most likely a
problem with the (AC or DC) input power or with one of the internal DC lines. If so,
there are no installation adjustments that you should make; contact a service
representative for further instructions.
Verify that the normal LED on the RSP goes on and stays on. This indicates if the system
software booted successfully. If the LED goes on, proceed to step 6. If it does not go on,
do the following:
•
Check the ejector levers and captive installation screws on the processor modules. If
any appear loose, use the ejector levers to reseat the module, and then tighten the
captive installation screws to secure it. Toggle the power off and back on again.
•
If the RSP normal LED still remains off, note whether the CPU halt LED goes on, and
contact a service representative.
When the system boot is complete, the RSP begins to initialize the interface processors.
During initialization, the LEDs on each interface processor behave differently (most flash
on and off). The enabled LED on each interface processor goes on when initialization is
completed.
•
If the enabled LED on all interface processors goes on, the system has booted
successfully and is now functional.
•
If the RSP LEDs previously indicated a successful system boot, but none of the
enabled LEDs on interface processors go on, suspect that one of the interface
processors has shifted out of its backplane connector and hung the bus. Turn off the
power, and then use the ejector levers to release each interface processor and reseat
them in their slots. (See the “Moving Processor Modules from the Old Chassis to the
New Chassis” section on page 18 for removal and insertion steps.) Tighten all captive
installation screws, and then return to Step 1.
Step 7
If the enabled LED on a single interface processor remains off, suspect that the interface
processor has shifted out of its slot. Use the ejector levers to release the interface
processor and reseat it in the backplane. (Refer to the “Moving Processor Modules from
the Old Chassis to the New Chassis” section on page 18 for removal and insertion steps.)
Tighten both captive installation screws, and then return to Step 1.
Step 8
If an enabled LED still fails to go on after performing these steps, suspect that the specific
interface processor has failed. Contact a service representative.
Step 9
Verify that the console terminal displays a script and system banner similar to the
following:

After the system initializes, enter the various show commands to display the status of the
system and individual interfaces, and ensure that they are operating according to their
previous configuration. (For descriptions and examples of these commands, refer to the
following section, “Verifying the Installation Using show Command Descriptions and
Examples.”)

Verifying the Installation Using show Command Descriptions and Examples
When the system starts up and operates successfully, the replacement procedure is complete, and
you can resume normal operation.
If the system still fails to start up or operate properly, or if you isolate the cause of the problem to a
failed component, contact a service representative for further assistance.
Note After you verify a successful installation, gather the old chassis and any remaining spares and
parts. If the old chassis is still mounted in a rack, follow the steps in the “Removing the Existing
Chassis from the Rack” section on page 13” to remove it. Place spare interface processors or
interface processor fillers in the chassis slots, and move the chassis to the appropriate location for
storage or shipment.
Verifying the Installation Using show Command Descriptions and Examples
This section describes the various show commands that you can use to display system status and
configuration. If you installed the interface processors in the same slot locations that they occupied
in the old chassis, the interfaces should retain the same configuration. If you installed the interface
processors in different slot locations, the system will recognize the interfaces, but you will have to
use the configure command to reconfigure and enable them.
You can check the version of the default ROM image either by removing the board and checking the
ROM labels or by configuring the interface or system software to boot from ROM, restarting the
system, and using these same commands to check the running version.
