Monitoring the Control Board Status
Steps To Take To check the Control Board status, follow these steps:
1.
Check the Control Board Environmental Status on page 306
2.
Check the Control Board Status from the Craft Interface on page 307
Step 1: Check the Control Board Environmental Status
Action To check the Control Board environmental status, use the following CLI command: user@host> show chassis environment cb
Sample Output t640@host> show chassis environment cb

What It Means The command output lists the Control Board state, redundancy status, temperature, power supply voltages, and circuitry revision level. If you do not specify a Control
Board slot number, the command displays the environmental status for each
Control Board installed in the router chassis. If you specify a Control Board slot number, the command displays the status for that slot only.
