Maintaining MX240 MPCs

Purpose
For optimum router performance, verify the condition of the Modular Port Concentrators (MPCs). The
router can have up to three MPCs mounted horizontally in the card cage at the front of the chassis.
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 State in the column labeled State indicates that the MPC is functioning normally:
