Troubleshooting the MX480 FPCs

Problem

The FPCs are not functioning normally.

Solution

Monitor the green LED labeled

OK

above the FPC on the craft interface as soon as an

FPC 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 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, during which the

OK

LED blinks. When the FPC is online and functioning

normally, the

OK

LED lights green steadily.

Make sure the FPC is properly seated in the midplane. Check that each ejector handle
has been turned clockwise and is tight.

Check the

OK/FAIL

LED on the FPC and

OK

and

FAIL

FPC LEDs on the craft interface.

When the FPC is online and functioning normally, the

OK

LED lights green steadily.

Issue the

show chassis fpc

command to check the status of installed FPCs. As shown

in the sample output, the value

Online

in the column labeled

State

indicates that the

FPC is functioning normally:

user@host>

NOTE:

The

show chassis fpc

command displays the status of the FPCs.
