Replacing the CIP and Routing Engine Interface Port Cables

The CIP is located to the left side of the FPC card cage, as shown in Figure 1. It houses the Routing Engine interface ports, which accept connections to external management and alarm-reporting devices.

The CIP is field-replaceable, but you must power off the router before removing or installing it. It weighs about 6.5 lb (3 kg). The cables and wire that connect to the Routing Engine interface ports are hot-removable and hot-insertable.

To replace the CIP and cables connecting to the Routing Engine interface ports, perform the following procedures:

2.On the console or other management device connected to the master Routing Engine, enter CLI operational mode and issue the following command to shut down the router software. (If two Routing Engines are installed, also issue the command on the backup Routing Engine.)
