Maintaining MX480 MICs

Purpose

For optimum router performance, verify the condition of the MICs.

Action

On a regular basis:

• Check the LEDs on MIC faceplates. The meaning of the LED states differs for various MICs. For more information, see the MX Series 3D Universal Edge Routers Line Card Guide. If the MPC that houses the MIC detects a MIC failure, the MPC generates an alarm message to be sent to the Routing Engine.
• Issue the CLI show chassis fpc pic-status command. The MIC slots in an MPC are numbered PIC 0/1 and PIC 2/3, left to right:
