Removing and Installing a PRP
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 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 Cisco recommends that you do not remove a PRP while the system is operating. Doing so will cause 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. Cisco strongly recommends that you avoid configuring your router using mixed RP cards. If RP redundancy is desired, you must install two PRPs.

Removing a PRP
When you remove a PRP from a slot, be sure to use the ejector levers, which help to ensure that the PRP is fully dislodged from the backplane connector. A PRP that is only partially removed from the backplane can halt the system. (See Figure 6.)
Caution Before you replace the PRP, back up the running configuration to a TFTP server or a Flash disk so that you can retrieve it later. If the configuration is not saved, it will be lost and you will have to reenter the entire configuration manually. This procedure is not necessary if you are temporarily removing a PRP; lithium batteries will retain the configuration in memory until you replace the PRP in the system.
