    Monitoring the Craft Interface Status

    Viewing the Craft Interface Status

    Purpose

    To determine a craft interface failure by checking the craft interface status.

    Action

    To view the craft interface status, look at the craft interface panel on the front of the router chassis.

    When the craft interface fails, you might not see any lights on the craft interface panel and the LCD display will be blank. In addition, the buttons on the panel might not work as indicated.

    You can view the craft interface information with the following command:

    user@host> show chassis craft-interface

    If the craft interface fails, you can still view current craft interface information at the command line. A craft interface failure or removal generates a red alarm.

    Checking the Craft Interface Environmental Status

    Purpose

    To check the environmental status of the craft interface.

    Action

    To view the craft interface status, use the following command:

    user@host> show chassis environment

    Sample Output

    For M5, M10, M20, and M40 routers:

    user@host>  show chassis environment
    Class Item                   Status     Measurement
    [...Output truncated...]
    Misc  Craft Interface        OK        
    

    For M40e and M160 routers:

    user@host>  show chassis environment
    Class Item                   Status     Measurement
    [...Output truncated...]
          FPM CMB                OK         32 degrees C / 89 degrees F
          FPM Display            OK         32 degrees C / 89 degrees F
    [...Output truncated...]
    

    For M40e and M160 routers:

    user@host>  show chassis environment
    Class Item                   Status     Measurement
    [...Output truncated...]
          FPM GBUS               OK         28 degrees C / 82 degrees F
          FPM Display            OK         31 degrees C / 87 degrees F
    [...Output truncated...]
    

    Meaning

    For M5, M10, M20, and M40 routers, the command output displays the craft interface state, which can be OK or Absent.

    For M40e and M160 routers, the command output displays the FPM Chassis Management Bus (CMB) status and the FPM display status, which can be OK or Absent.

    For M320 routers, the command output displays the FPM CMB status only.

    For T320 routers and T640 routers, the command output displays the FPM circuitry and the FPM display status, which can be OK or Absent.

    (For M40e, M160, M320, and T320, T640, T1600, and TX Matrix routers) To monitor the craft interface environmental status, use the following command:

    user@host> show chassis environment fpm
    user@host> show chassis environment fpm
    FPM status:
      State                       Online
      FPM CMB Voltage:
        5.0 V bias           5030 mV
        8.0 V bias           8083 mV
      FPM Display Voltage:
        5.0 V bias           4998 mV
      FPM CMB temperature      34 degrees C / 93 degrees F
      FPM Display temperature  35 degrees C / 95 degrees F
      CMB Revision             12
    

    The command output displays the status of the FPM or craft interface, which can be Online or Offline. It also displays information about the power supplied to the FPM CMB or FPM GBUS, information about the FPM display power supply, the temperature of the air flowing past the FPM CMB or FPM GBUS and the FPM display, and the CMB or GBUS revision level.
