This document provides instructions for replacing Cisco 7010 and Cisco 7505 chassis as spare parts.

Note When referring to both the Cisco 7010 and Cisco 7505 chassis, the term the chassis will be

used.

Chassis are available as spare parts, and include all of the components required for operation except
the processor modules. After you replace the chassis, you must move the processor modules from
your old chassis into your new chassis.

The replacement chassis do not include the cable management or rack-mounting hardware kits. You
can move the rack-mounting hardware and cable management brackets from the existing chassis, or
order either kit as a spare part, which will ship with installation instructions.

Captive screws

Two captive slotted screws secure the chassis cover panel to the noninterface processor end of the
chassis. The cover shields against electromagnetic interference (EMI) and helps direct the flow of
cooling air through the chassis. Therefore, never operate the router with the cover removed.

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 followingguidelineswill help to ensure your safetyand 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.

Safety with Electricity

• 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.

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.

Lifting Safely

A fully configured chassis weighs approximately 70 pounds. 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 (ESD) Damage

Electrostatic discharge (ESD) damage, which can occur when electronic boards or components are
handled improperly, can result in complete or intermittent failures. The processor modules each
comprise 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 anycomponents, connector pins,
or the metal fingers on the edge connector).

Prerequisites

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 removingor 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.

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

should be between 1 and 10 megohms.

Prerequisites

Cable Strain Relief

If possible, position the newreplacement chassis close enough to the existing system so that you can
avoidhaving to disconnect power and interfacecables. 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

• On the DC-input power supply, a nylon cable tie is used to fasten the power cable to a bracket

• Serial interface cables (all types) use thumbscrewson the cable connectors that secure the cable

• Ethernet interface cables use either slide-type locks or thumbscrews. Although all Ethernet

chassis), a cable retention clip (see Figure 1 or Figure 2) snaps up around the plug on the power
cord to prevent it from being inadvertently pulled out of the receptacle. Before attempting to
disconnect the power cable, be sure to push the retention clip down away from the plug.

located just below the input terminal block. Carefully cut this cable tie before you disconnect the
power cable leads from the terminal block, and replace the cable tie after you install the new
chassis and wire the power cable leads to the terminal block.

to the Fast-Serial Interface Processor (FSIP) port.

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, Fiber Distributed Data Interface (FDDI) connectors use small plastic arms on two

sides ofthe connector that act like springs andare constrained by the inside of theconnector port.
To remove a multimode cable from a 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 7010 Hardware Installation
and Maintenance or Cisco 7505 Hardware Installation and Maintenance publications.

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 70 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.

Prerequisites

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.

Also, ensure that your new chassis allows sufficient clearance for maintenance: to remove and
replace processor modules 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 to remove or install each of the major components.
