Maintain the FEB

The Forwarding Engine Board (FEB) installs into the rear of the chassis, as shown in Figure 3. To maintain the FEB, perform the following procedures on a regular basis:

• Check the system logging messages on the management console. The FEB notifies the Routing Engine of any errors it detects during normal operation.
• Issue the CLI show chassis feb command to check the status of the FEB.
