    Monitor the Redundant PCG Environmental Status

    Purpose

    To check the redundant PCG by monitoring the redundant PCG environmental status.

    Action

    To monitor the PCG environment status, use the following command:

    user@host> show chassis environment

    Sample Output

    user@host> show chassis environment
    Class Item                   Status     Measurement
    Power PEM 0                  OK        
          PEM 1                  OK        
    Temp  PCG 0                  OK         41 degrees C / 105 degrees F
          PCG 1                  OK         39 degrees C / 102 degrees F
    [...Output truncated...]
    

    Meaning

    The command output displays the slot number, status, and temperature of each PCG.

    If there is a problem with the PCG status, you can display more detailed PCG environmental information with the following command:

    user@host> show chassis environment pcg

    The command output is as follows:

    PCG 0 status:
      State                           Online - PFE clock source
      Temperature                  41 degrees C / 105 degrees F
      Frequency:
        Setting                125.00 MHz
        Measurement            125.03 MHz
      Power:
        3.3 V                    3266 mV
        5.0 V bias               4981 mV
        8.0 V bias               8168 mV
      CMB Revision                 12
    PCG 1 status:
      State                           Online
      Temperature                  39 degrees C / 102 degrees F
      Frequency:
        Setting                125.00 MHz
        Measurement            125.03 MHz
      Power:
        3.3 V                    3271 mV
        5.0 V bias               4971 mV
        8.0 V bias               8175 mV
      CMB Revision                 12
    

    The command output displays the status for each PCG. The operating status can be Present, Online, Offline, or Empty. If Online, it can be the current PFE clock source (master) or backup. The command output displays the temperature of the air flowing past the PCG and the frequency setting and measurement for the PCG. The command output also displays information about the PCG power supplies and the revision level of the chassis management bus (CMB) backup.
