Troubleshooting

Confirming the Connection (LED Indicator)

When the notebook computer is powered “ON,” and the DFE- 690TXD is inserted into an open slot connector, please check the following items if your LED light is not “ON.” When all items are working, your DFE-690TXD’s direct port LED light should light up green (“Link” state.)

1.Make sure that your Ethernet Cat5 cable is in good working order.

2.Make sure that your hub or switch is powered “ON” and functioning properly.

3.If the LED remains dark without any apparent cause, check the “Device Manager.” If there is an exclamation point next to the DFE-690TXD, then double-click to open. A message indicating the error will appear.

4.After verifying that the DFE-690TXD has been installed correctly, check steps 1 and 2 again. If you continue to encounter a problem, please call D-Link Technical Support for assistance.
