Troubleshooting the CFEB

If the CFEB fails, the forwarding and routing functions of the router halt immediately and do not resume until the CFEB failure has been corrected.

To troubleshoot a CFEB, follow these guidelines:

■Make sure the CFEB is properly seated in the midplane. Use a Phillips screwdriver to ensure that the screws are securely tightened.

■Check the alarm LEDs on the craft interface. A CFEB failure generates either a red or yellow alarm, depending on the type of failure.
