Troubleshooting the MX960 MPCs

Description: The MPCs are not functioning normally.

Monitor the green LED labeled OK above the MPC on the craft interface as soon as an MPC is seated

in an operating router.

The Routing Engine downloads the MPC software to it under two conditions: The MPC is present when

the Routing Engine boots Junos OS, and the MPC is installed and requested online through the CLI or

push button on the front panel. The MPC then runs diagnostics, during which the OK LED blinks. When

the MPC is online and functioning normally, the OK LED lights green steadily.

Make sure the MPC 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 MPC and OK and FAIL line card LEDs on the craft interface. When the

MPC is online and functioning normally, the OK LED lights green steadily.

Issue the show chassis fpc command to check the status of installed MPCs. As shown in the sample

output, the value Online in the column labeled State indicates that the MPC is functioning normally:
