Maintaining Mx480 Fpcs - Juniper MX480 Hardware Manual

Maintaining MX480 FPCs

Purpose
The MX480 router can have up to three Flexible PIC Concentrators (FPCs) installed horizontally in the
front of the chassis. For optimum router performance, verify the condition of the FPC.
Action
On a regular basis:
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:
