Action On a regular basis:
• 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 Online in the column labeled State indicates
that the DPC is functioning normally:
user@host> show chassis fpc
Temp CPU Utilization (%) Memory Utilization (%)
Slot State (C) Total Interrupt DRAM (MB) Heap Buffer
0 Online 41 9 0 1024 15 57
1 Online 43 5 0 1024 16 57
2 Online 43 11 0 1024 16 57
For more detailed output, add the detail option. The following example does not specify
a slot number, which is optional:
user@host> show chassis fpc detail
