The Ethernet Link LED (E1) illuminates (green) if the Ethernet is connected. When the
LED is blinking, it indicates that there is data traffic on the Ethernet link.
E1 is used for all models to connect to the network.

when loading factory defaults. If the LED is off or steady, it indicates the system is not
