D-Link DFE-520TX 32-bit PCI Network Adapter
Introduction
Thank you for choosing the D-Link DFE-520TX, the value leader among Fast Ethernet adapters for PCI Bus personal computers. This introduction gives a general description of the newer networking technologies found on the DFE-520TX. The DFE-520TX provides IEEE 802.3x Flow Control Enhancements, which are needed for a network adapter to function with a switch. In full-duplex mode, the MAC implements the PAUSE control function. This means that when a switch is connected in full-duplex mode, and it senses that its buffer will overflow shortly, the switch will transmit one standard Ethernet packet that causes the DFE-520TX to pause for a period, thus avoiding internal buffer overflow and packet loss.

Installing the Adapter
- Shut down the computer, unplug its power cord, and remove the chassis cover.
- Insert the contact edge of the DFE-520TX card into the connector of any available PCI Bus Master expansion slot.
- Consult the computer manufacturer before opening the case to ensure that you adhere to warranty guidelines.
- Install the bracket screw that secures the card to the computer chassis.
- Replace the computer’s chassis cover.
- Reconnect the computer’s power cord, and switch the computer power on.
Connecting the Network Cable
Category 5 UTP cable qualifies for both 100BASE-TX Fast Ethernet and 10BASE-T Ethernet cabling rules. The maximum length of any single cable segment is 100 meters. Please keep in mind, however, that the maximum cable run between any two stations in a collision domain is 205m.
Troubleshooting
If you experience any problems with the adapter, check to see:
- that the appropriate driver is loaded;
- that the proper grade of cable is employed for the network connection;
- that the supporting hub is properly qualified for the application.\
The DFE-520TX Adapter features one LED indicator - Link/Activity – Steady green indicates good linkage between the DFE-520TX and its supporting server or switch. Flashing green indicates activity (transmitting or receiving) within the adapter.
