Troubleshooting the MX2010 MPCs
Problem
Description
The following LEDs indicate a problem with an MPC:
The red FAIL LED above the MPC is lit.
The green OK LED above the MPC is not lit.
Solution
To troubleshoot an MPC:
Monitor the green LED labeled OK above the MPC on the craft interface as soon as an MPC is seated in an operating router.
Note:The Control Board and Routing Engine (CB-RE) downloads the software to the MPC under two conditions: The MPC is present when the CB-RE boots Junos OS, and the MPC is installed and requested online through the CLI or the 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.
Look at the display on the craft interface to check the status of the MPC and the MICs that are plugged into it.
Verify that the MPC is properly seated in the top and bottom backplanes of the adapter card (ADC). Check that each knob has been turned clockwise and is tight.
Check the OK/FAIL LED on the MPC, and the OK and FAIL line-card LEDs, LC0 through LC9, on the craft interface. When the MPC is online and functioning normally, the OK LED lights green steadily.
Check the status of an MPC by using the
show chassis fpcCLI command. As shown in the sample output, the value Online in the column labeled State indicates that the MPC is functioning normally:user@host> show chassis fpc Temp CPU Utilization (%) Memory Utilization (%) Slot State (C) Total Interrupt DRAM (MB) Heap Buffer 0 Online 37 8 0 2048 10 13 1 Online 35 6 0 2048 13 13 2 Online 37 9 0 2048 17 13 3 Empty 4 Online 37 9 0 2048 17 13 5 Empty 6 Empty 7 Empty 8 Empty 9 Online 37 11 0 2048 21 13Use the detail option to display more detailed information.
