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:
on page xxiv.
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.
