Troubleshooting FPCs
As soon as an FPC is seated in an operating router, the Routing Engine downloads
the FPC software to it. The FPC then runs diagnostics and enables the PICs housed
on it. During this time, the green LED labeled
OK
above the FPC on the craft interface
blinks. When the FPC is online and functioning normally, the
OK
LED lights steadily.
To troubleshoot the FPCs, follow these guidelines:
If the red LED labeled
FAIL
above the FPC on the craft interface lights steadily,
check the LCD on the craft interface for a message about the status of the FPC
and the PICs housed in it.
Make sure the FPC is properly seated in the midplane—use a Phillips
screwdriver to check that the screws at the top and bottom of the card carrier
are tight.
To check the status of an FPC, issue the following CLI command:
user@host> show chassis fpc
