Maintaining MX480 PICs

Purpose

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

Action

On a regular basis:

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