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

• 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
