Maintaining MX960 FPCs

 

Purpose

The router can have one Flexible PIC Concentrator (FPC) installed vertically in two DPC slots at the front of the chassis. For optimum router performance, verify the condition of the FPC.

Action

On a regular basis:

  • Check the LEDs on the craft interface directly above the FPC. The green LED labeled OK lights steadily when an FPC is functioning normally.

  • Check the OK/FAIL LED on the FPC. If the FPC detects a failure, the FPC sends an alarm message to the Routing Engine.

  • Issue the CLI show chassis fpc command to check the status of the installed FPC. As shown in the sample output, the value Online in the column labeled State indicates that the FPC 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 following example shows an FPC installed in DPC slots 1 and 2:

    user@host> show chassis fpc pic-status
    Note

    An FPC takes up two DPC slots when installed on an MX Series router. The slot number corresponds to the lowest numbered DPC slot.

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