    Checking the Control Board Status

    Purpose

    To monitor the Control Board as part of the host subsystem on T320 and T640 routers. For more information about monitoring the Control Board, see Checklist for 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

    Meaning

    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.
