    Monitor the FEB Status

    If the FEB fails, no information about chassis components is available through the CLI.

    To monitor the FEB status:

    1. Display the FEB Environmental Status
    2. Display the FEB Detailed Status

    Display the FEB Environmental Status

    Purpose

    To isolate problems in the FEB by checking the FEB environmental status.

    Action

    To display the FEB environmental status, use the following command:

    user@host> show chassis environment

    Sample Output

    user@m5-host> show chassis environment
    Class Item                   Status     Measurement
    Power Power Supply A         OK
          Power Supply B         OK
    Temp  FPC Slot 0             OK         32 degrees C / 89 degrees F
          FEB                    OK         31 degrees C / 87 degrees F
          PS Intake              OK         26 degrees C / 78 degrees F
          PS Exhaust             OK         31 degrees C / 87 degrees F
    [...Output truncated...]
    

    Meaning

    The command output displays the temperature and status of the FEB, which can be OK, Failed, or Absent.

    Display the FEB Detailed Status

    Purpose

    To obtain detailed information about the FEB status.

    Action

    To display more detailed FEB status, use the following command:

    user@host> show chassis feb

    Sample Output

    user@host> show chassis feb
    FEB status:
      Temperature                 37 Centigrade
      CPU utilization              0 percent
      Interrupt utilization        0 percent
      Heap utilization            16 percent
      Buffer utilization          43 percent
      DRAM                        64 Mbytes
      Internet Processor II          Version 1, Foundry IBM, Part number 9
      Start time                     1999-01-24 16:24:42 UTC
      Uptime                         2 hours, 21 minutes, 28 seconds
    

    Meaning

    The command output displays the temperature of the air passing by the FEB, in degrees Centigrade. It displays the total percentage of CPU, interrupt, heap space, and buffer space being used by the FEB processor, including the total DRAM available to the FEB processor. The command output displays the time when the FEB started running and how long the FEB has been running. A short uptime can indicate that there is an FEB problem.
