This document provides instructions for replacing the Cisco 7513 chassis, which is available as a
spare part.
Note Through this document, the term the chassis is be used to refer to the Cisco 7513 chassis.
The chassis is available as a spare part, and includes all of the components required for operation
except the processor modules and power supplies (MAS-7513=), or as a spare with power supplies
(CHAS-7513-DC= or CHAS-7513-AC=).
After you replace the chassis, you must move the processor modules from your old chassis into your
new chassis.
The replacement chassis does not include the cable-management or rack-mounting hardware kits.
You can move the rack-mounting hardware and cable-management bracket from the existing chassis,
or order either kit as a spare part, which will ship with installation instructions.

What Is the Cisco 7513?
What Is the Cisco 7513?
The Cisco 7513 is a 13-slot router chassis, which uses the RSP2 and CxBus and CyBus interface
processors. The chassis provides up to eleven interface processor slots. Although the chassis uses
two high-speed, 1.067-gigabit-per-second (Gbps) CyBuses, it can accommodate all CxBus-based
interface processors.
Any combination of network interface types is supported: Ethernet, Token Ring, Fiber Distributed
Data Interface (FDDI), channel attachment, multichannel, serial, and so forth. The RSP2 and
interface processors are keyed with guides on the backplane to prevent them from being fully
inserted in the wrong slot.
Figure 1 shows the interface processor end of the Cisco 7513, which provides access to the thirteen
slots, the system blower, and the power supplies. When facing the interface processor end of the
chassis, the RSP2 is installed in RSP slot 6 or 7.
The eleven interface processor slots are numbered from slot 0 (far left) through slot 5 (CyBus 0) and
slot 8 through slot 12 (CyBus 1).

Prerequisites
Prerequisites Before you begin this installation, review the safety guidelines in this section to avoid injuring
yourself or damaging the equipment. This section also provides a list of the tools that you need to
perform this replacement.
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.
•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.
•Never install equipment that appears damaged.
•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 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 has been
disconnected at the network interface.
•Use caution when installing or modifying telephone lines.

4Cisco 7513 Chassis Replacement Instructions
Prerequisites
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.
•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.
•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.
•Place removed processor modules board-side-up on an antistatic mat or in a static shielding bag.
•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.
•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.
Caution Forsafety, periodicallycheck theresistance value of theantistatic strap.The measurement
should be between 1 and 10 megohms.

Prerequisites
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, nylon cable ties are used 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.
•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 7513 Hardware Installation
and Maintenance publication.
Preparing the Work Area
Although some network downtime is unavoidable while you remove the RP and SP (or SSP) or
RSP1 from their respective 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.

6Cisco 7513 Chassis Replacement Instructions
Prerequisites
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, youmust disconnect all power and network interface cables.
Also, 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 2 shows the chassis footprint and the clearance required.

Replacing the Chassis
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 (panhead screws are included with the brackets):
—Number 1 Phillips screwdriver
—Cable-management bracket
—Two M3 x 8-mm, Phillips panhead screws
•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
—the 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 the Chassis
The Route Switch Processor (RSP2) is a required system component and should only be removed
when the system is not operation, although power can be on to the chassis. All interface processors
support online insertion and removal (OIR); however, after installing an interface processor on line,
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 section “Installing the Cable-Management Bracket” on page 12.

8Cisco 7513 Chassis Replacement Instructions
Replacing the Chassis
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 3.
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.
Assess your rack and lab configuration and the equipment you have available, 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 Rack-Mount Kit Installation Instructions (Document Number
78-2023-xx). After you install the new chassis in the rack and install the cable-management
brackets, proceed to the section “Moving Processor Modules from the Old Chassis to the New
Chassis,” on page 13, 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.”

Cisco 7513 Chassis Replacement Instructions 9
Replacing the Chassis
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 3), 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.
Figure 3 Chassis, Rack Brackets, and Ears
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.
Follow these steps to remove the existing chassis from the rack:
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
secure the chassis ears to the rack rails.

Replacing the Chassis
Step 3 Pull the chassis out of the rack and place it on the floor or a table.
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 4. To prevent
damage to the air intake vent below the card cage, do notlift 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 4.
Figure 4 Lifting the Chassis
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, 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.
Follow these steps to install the chassis in the rack:
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 4.
Step 2 Grasping the chassis as shown in Figure 4, slowly lift the chassis in unison. To prevent
injury, avoid sudden twists or moves.
