Troubleshooting - D-Link DFE-550FX User Manual

Troubleshooting

If you experience any problems with the adapter, first verify that the
appropriate driver is loaded, that the proper grade of cable is employed for
the network connection, and that the supporting hub is functioning properly.
Ascertain that the adapter card is fully and firmly seated in the slot
connector.
Check the length and rating of connecting cables.
Ascertain that the adapter PCI slot is not deactivated at the BIOS
level. The CMOS Setup utility in PCI computers ordinarily provides the
option to activate or deactivate PCI slots.
Replace the adapter in question with a verified adapter and run NIC
(software) diagnostic tests.
Install the questioned adapter in another PCI computer and run the
tests again.
Remove all other PCI adapters from the computer and run the tests again. If
the verification/diagnostic run is then normal, then there is probably an
interrupt number conflict which will have to be resolved manually by a
CMOS Setup utility run after you have reinstalled all of the expansion
cards.
The DFE-550FX Adapter features three LED indicators to assist in
network diagnostics:

adapter.
