    Check the Host Module Status

    Purpose

    To verify the host module status by using the command line or checking the LEDs on the craft interface.

    Action

    To check the host module status, use the following command:

    user@host> show chassis craft-interface
    user@host> show chassis craft-interface
    [...Output truncated...]
    Front Panel System LEDs:
    Host     0    1
    ------------------------
    OK       *    .
    Fail     .    .
    Master   *    .
    [...Output truncated...]
    

    Meaning

    (M40e and M160 routers) The Front Panel System LEDs show the Routing Engine Host 0 and Host 1 LED state. The state can be OK, Fail, or Master. An asterisk (*) indicates the operating state.

    Look at the LEDs on the craft interface.

    The host module LEDs are located on the upper right corner of the craft interface. Two sets of LEDs indicate the host module status: the set labeled HOST0 reports the status of the Routing Engine in slot RE0 and the MCS in slot MCS0, while the set labeled HOST1 reports the status of the Routing Engine in slot RE1 and the MCS in slot MCS1. Each set includes three LEDs: MASTER (green), ONLINE (green), and OFFLINE (red).

    Figure 1 shows the M40e and M160 router craft interface LEDs.
