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-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.
