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.
Ethernet LEDs
IP IP FUNCTION. This LED blinks when the IP function of the modem/router is operating
normally. It shows a steady light when powering-up, initializing, or flashing the firmware.
SPD SPEED. This LED lights when the Ethernet is linked at 100 Mbps. If it is not lit, the Ethernet is
linked at 10 Mbps.
