Troubleshooting - D-Link DFE-550FX User Manual

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.
1.
Ascertain that the adapter card is fully and firmly seated in
the slot connector.
2.
Check the length and rating of connecting cables.
3.
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.
4.
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 run is then normal, then there is
probably an interrupt number conflict that 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:
•
LINK

500FX and the supporting network device .
•
ACTIVE
Flashing green indicates activity (transmitting or receiving)
within the adapter.
•
FULL (duplex) Indicator
This LED is ON for full duplex connections and OFF when
connected at half duplex
