Maintaining MX960 DPCs

 

Purpose

The router can have up to 12 Dense Port Concentrators (DPCs) mounted vertically in the DPC card cage at the front of the chassis. For optimum router performance, verify the condition of the DPCs.

Action

On a regular basis:

  • Check the LEDs on the craft interface directly above each DPC slot. The green LED labeled OK lights steadily when a DPC is functioning normally.

  • Check the OK/FAIL LED on the DPC. For more information, see MX Series Interface Module Reference. If the DPC detects a failure, the DPC sends an alarm message to the Routing Engine.

  • Check the status of installed DPCs by issuing the CLI show chassis fpc command to check the status of installed DPCs. As shown in the sample output, the value Online in the column labeled State indicates that the DPC is functioning normally:

    user@host> show chassis fpc

    For more detailed output, add the detail option. The following example does not specify a slot number, which is optional:

    user@host> show chassis fpc detail
  • Issue the CLI show chassis fpc pic-status command. The DPC slots are numbered from 0 through 5, 2/6, 7 through 11, left to right:

    user@host> show chassis fpc pic-status

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