Maintaining the T320 Control Boards



For optimum router performance, verify the condition of the router’s control boards.


On a regular basis:

  • Check the LEDs on the control board faceplate. For more information, see T-CB LEDs

  • Issue the show chassis environment cb command to check the status of the control boards. The output is similar to the following:

    user@host> show chassis environment cb

For further description of the output from the command, see show chassis environment cb.
