About LED Indications
This section identifies problems that the LEDs can indicate, and suggests possible solutions.
Why doesn’t the 10/100BaseT link LED light?
For BRI gateways, the 10/100 Base-T link LED is embedded in the 10/100BaseT jack on the left side of
the gateway front panel For PRI gateways, the 10/100Base-T link LED is the embedded LED in the
Ethernet port nearest the Serial port. When this LED lights up, it indicates that the gateway is connected
to the network.
•
Make sure that the Ethernet cable is connected to the 10/100BaseT-1 socket on the front panel of the
gateway. The 10/100BaseT port in the rear panel is not supported.
•
Make sure that the devices at both ends of the link are powered up.
•
Make sure that you are using an RJ-45 jack with standard wiring to connect the Ethernet cable to
the gateway 10/100BaseT-1 socket.
•
Reset the gateway by pressing the RST button on the front panel or by clicking the Reset button in
the Gateway interface.
