Power (and signal) LED (front panel) —
Amber — The unit is receiving power, either locally or remotely (on the DTP cable).
Green — The unit is receiving an active DVI input, either on the DVI input if a
transmitter, or transmitted on the DTP cable if a receiver.
Power LED (rear panel) —
Amber — The unit is receiving power remotely (on the DTP cable).
Green — The unit is receiving power locally.
