Removing and Installing a PRP

Required Tools and Equipment

You need the following tools and parts to remove and install a PRP:

• Flat-blade or Phillips screwdriver

• ESD-preventive wrist strap and instructions

• Antistatic mat, foam pad, or bag for the removed PRP. Place the removed PRP into an antistatic bag

if you plan to return it to the factory, or on an antistatic mat or foam if you are replacing components

and will reinstall the PRP.

Working with Electrical Equipment

Follow these basic guidelines when working with any electrical equipment:

• Before beginning any procedure 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 when potentially hazardous conditions exist; never assume that power has been

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.

Removing and Installing a PRP

The following sections describe the procedures for removing and installing a PRP as well as removing

and installing other field-replaceable hardware on the PRP-2 board. Before beginning the procedures,

verify that your system meets the minimum requirements as described in the “Preparing for Installation”

section on page 17.

• Removing a PRP, page 20

• Installing a PRP, page 22

Note The procedures in the following sections use illustrations of a Cisco 12404 Internet Router to support

the descriptions of installing and removing a route processor card. The card cages of Cisco XR 12000

Series Routers differ in many ways. However, the process of installing and removing a route processor

card are basically the same across the entire chassis line. Therefore, separate procedures and illustrations

for each chassis are not included in this publication.

Caution We recommend that you do not remove a PRP while the system is operating. Doing so causes the system

to stop forwarding packets and might cause the system to cease network operation. If you are upgrading

your router from a GRP to a PRP, you must first power down the router and then switch out the RP cards.

We strongly recommends that you avoid configuring your router using mixed RP cards. If RP

redundancy is desired, you must install two PRPs.
