Checking the Control Board Status

This section provides a brief description of monitoring the Control Board as part of the host subsystem on T320 routers and T640 routing nodes. For more information about monitoring the Control Board, see Monitoring the Control Board.

Action

To monitor the Control Board environmental status, use the following CLI command:

user@host> show chassis environment cb

Sample Output

user@host> show chassis environment cb

What It Means

The command output displays environmental information about both Control Boards installed in the router. It displays the Control Board slot, operating status, temperature of air flowing past the Control Board, power supply, and circuitry and field programmable gate array (FPGA) revision information.

The Control Board status can be Present, Online, Offline, or Empty. The command also indicates whether the Control Board is master.
