(Color: red)
On (steady) The battery voltage has fallen below a
threshold level, or the battery is missing or not
connected.
Off The battery is functional.

Channel 1
(Color:
green or red)
Solid green The Ethernet port is functioning properly and is
connected to an active Ethernet network.
Flashing green The Ethernet port is functioning properly,
connected to an active Ethernet network, and is
transmitting packets.
