Troubleshooting the M10i PICs

 

Problem:

Description: The PICs are not functioning normally.

Solution

To troubleshoot the PICs:

  1. Check the status of the LEDs located on the PIC faceplate. Many PICs have an LED labeled STATUS on their faceplate. Some PICs have additional LEDs, often one per port. For information about the LEDs on each PICs, see the M10i Multiservice Edge Router Interface Module Reference.
  2. Issue the following CLI command to check the status of a PIC:
    user@host> show chassis fpc pic-status

    For further description of the output from the command, see the CLI Explorer.

    The PIC slots are numbered from 0 through 3, right to left

  3. If an LED is lit indicating a problem with the PIC, issue the show chassis alarms CLI command to view a more detailed description of the alarm cause:
    user@host>show chassis alarms

    For a list of messages that can appear in the output, see Table 1.

  4. If you are unable to correct the problem, replace the PIC with a spare. For instructions, see Replacing an M10i PIC. If the LEDs light correctly on the spare, the original PIC is faulty. Return it to Juniper Networks for replacement, as described in Contacting Customer Support.
