    Monitor the SCG Environmental Status

    Purpose

    To obtain information about the SCG environmental status.

    Action

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

    user@host> show chassis environment

    Sample Output

    t320@host>  show chassis environment
    Class Item                   Status     Measurement
    Power PEM 0                  Absent    
          PEM 1                  OK        
    Temp  SCG 0                  OK         30 degrees C / 86 degrees F
          SCG 1                  OK         29 degrees C / 84 degrees F
    [...Output truncated...]
    

    Meaning

    The command output displays the status and temperature for each SCG.

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

    user@host> show chassis environment scg

    The command output is as follows:

    t320@host>  show chassis environment scg
    SCG 0 status:

    The command output displays the status for each SCG slot 0 and 1. The operating status can be Present, Online, Offline, or Empty. If Online, it can be the clock source (Master clock) or backup (Standby). The command output displays the temperature of the air flowing past the SCG. The command output also displays information about the SCG power supplies and the SCG circuitry revision level.
