Maintaining MX2020 MPCs

date_range 09-Mar-21

Purpose

The router can have up to 20 Modular Port Concentrators (MPCs) mounted vertically in the MPC 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 a MPC is functioning normally.

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

  • Check the status of installed MPCs by issuing 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:
