Description: The FPCs or CFPCs are not functioning normally.
As soon as an FPC (or CFPC) is seated in an operating router, the Routing Engine
downloads the FPC software to it under two conditions: the FPC is present when the
Routing Engine boots the Junos OS, and the FPC is installed and requested online through
the CLI or push button on the front panel. The FPC then runs diagnostics and enables
the PICs housed on it. During this time, the green LED labeled
the craft interface blinks. When the FPC is online and functioning normally, the
LED lights steadily.
To troubleshoot the FPCs:
Make sure the FPC is properly seated in the midplane. Check that each ejector handle
has been turned clockwise and is tight.
