Check the LEDs on the craft interface directly above each DPC slot. The green LED labeled OK lights
steadily when a DPC is functioning normally.
Check the OK/FAIL LED on the DPC. If the DPC detects a failure, the DPC sends an alarm message to
the Routing Engine.
Issue the CLI show chassis fpc command to check the status of installed DPCs. As shown in the sample
output, the value State in the column labeled State indicates that the DPC is functioning normally:
user@host> show chassis fpc
Slot State
0 Online
