Maintaining the M7i CFEB and CFEB-E
Purpose
For optimum cooling, verify the condition of the CFEB.
Action
Check the LEDs on the CFEB or CFEB-E faceplate. The green LED labeled OK lights steadily on the CFEB or CFEB-E when it is functioning normally. For more information, see M7i Compact Forwarding Engine Board (CFEB) and Enhanced Compact Forwarding Engine Board (CFEB-E) Description.
Issue the CLI show chassis cfeb command to check the status of the CFEB (first output example) or the CFEB-E (second output example):
