    Troubleshooting PICs on the M40e Router

    Problem

    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 M40e Multiservice Edge Router PIC Guide.
    2. Issue the following CLI command to check the status of a PIC:

      user@host> show chassis fpc pic-status
        Slot 0   Online       DPC 40x 1GE R
    PIC 0  Online       10x 1GE(LAN)
    PIC 1  Online       10x 1GE(LAN)
    PIC 2  Online       10x 1GE(LAN)
    PIC 3  Online       10x 1GE(LAN)
  Slot 1   Online       MX FPC Type 3
    PIC 0  Online       1x OC-192 SONET
    PIC 1  Online       1x OC-192 SONET

      For further description of the output from the command, see the Junos OS System Basics and Services Command Reference.

      The PIC slots are numbered from 0 through 3, top to bottom

    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 a PIC in an M40e Router. 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.
