Maintaining MX960 MPCs

 

Purpose

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

Action

On a regular basis:

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

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

  • Issue the CLI show chassis fpc command to check the status of installed MPCs. 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

    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 MPC slots are numbered 0 through 5, bottom to top:

    user@host> show chassis fpc pic-status

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