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 the diagnostic test again.
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 that
will have to be resolved manually by a CMOS Setup utility run after you have reinstalled all of the
expansion cards.
The DFE-530TX Adapter features two LED indicators to assist in the resolving of 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-530TX and the device it is connected to. The LED will flash when the adapter is sending or
receiving data.
· Speed Indicator
This LED shows steady green (ON) when operating at 100Mbps. It is dark (OFF) when connected at
10Mbps.
