To check the status of a specific SCB, issue the show chassis environment cb command
and include the slot number of the SCB. The output is similar to the following:
user@host> show chassis environment cb 0
CB 0 status:

Maintaining MX480 DPCs
Purpose The router can have up to six Dense Port Concentrators (DPCs) mounted horizontally in
the DPC card cage at the front of the chassis. For optimum router performance, verify
the condition of the DPCs.
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. For more information, seeMX Series Interface Module
Reference . If the DPC detects a failure, the DPC sends an alarm message to the Routing
Engine.
• Check the status of installed DPCs by issuing 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
