Maintaining the T1600 Control Boards

Purpose

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

Action

On a regular basis:

• Check the LEDs on the control board faceplate.
• Issue the show chassis environment cb command to check the status of the T-CBs. The output is similar to the following:
  
  

  user@host> show chassis environment cb

  CB 0 status:
    State                           Online Master
    Temperature                  29 degrees C / 84 degrees F
    Power:
      1.8 V                    1809 mV
      2.5 V                    2496 mV
      3.3 V                    3295 mV
      4.6 V                    4687 mV
      5.0 V                    5042 mV
      12.0 V                  11985 mV
      3.3 V bias               3277 mV
      8.0 V bias               7472 mV
