    Description

    OK

    Green

    On steadily

    The switch module has passed the power-on self-test (POST) with no critical faults and is operational.

    Gigabit Ethernet switch module error (fault) (!)

    Yellow

    On steadily

    The switch module has failed the POST or detected an operational fault.

    Note: When the Gigabit Ethernet switch module error LED is lit, the system-error LED on the alarm panel is also lit

    Ethernet link (LINK)

    Green

    On steadily

    There is a connection (or link) to a device using that connector.

    Ethernet activity (Tx/Rx)

    Green

    Flashing

    Note: The flash frequency is proportional to the amount of traffic on the network link.

    Data is being transmitted or received (that is, activity is occurring) between that port and another device on the network link.
