Troubleshooting - D-Link DFE-550TX 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.
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.
Replace the adapter in question with a verified adapter and run NIC
(software) diagnostic tests.
5. Install the questioned adapter in another PCI computer and run the
tests again.
6.
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-550TX Adapter features three LED indicators to assist
in network diagnostics:
•
LINK/ACT Indicator
A steady green LED indicates that the card is receiving power and
there is a good link between the DFE-550TX and the device it is
connected to. The LED will flash when the adapter is sending or
receiving data.
•
100M Indicator
This LED shows steady green (ON) when operating at 100Mbps. It
is dark (OFF) when connected at 10Mbps.
•
FULL (duplex) Indicator
This LED is ON for full duplex connections and OFF when
connected at half duplex.
