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.


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.
