    Host Module LEDs on the M40e Craft Interface

    At the upper right corner of the craft interface (see M40e Craft Interface Description) are two sets of LEDs that indicate host module status: the set labeled HOST0 reports the status of the Routing Engine in slot RE 0 and MCS in slot MCS 0, and the set labeled HOST1 reports the status of the Routing Engine in slot RE 1 and the MCS in slot MCS 1. Each set includes three LEDs—a green one labeled MASTER, another green one labeled ONLINE, and a red one labeled OFFLINE. Table 1 describes the LED states.
