Front Panel LEDs
Once the power is connected, the LEDs on the front panel will provide information about the Ethernet
functions and the wireless modem functions.
The front panel of the Ethernet EDGE has a power LED, 3 Ethernet LEDs, 5 modem LEDs, and a
SIM card slot.
The front panel of the Ethernet GPRS is the same as the Ethernet EDGE.
The front panel of the Ethernet CDMA has the same LEDs as the EDGE modem. However, it does
not have a SIM card slot.
