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.
