Maintaining MX2020 MPCs
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
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:
