Troubleshooting

If the adapter can’t connect to the network

Make sure the cable is installed properly.

The network cable must be securely attached at both RJ-45 connections (adapter and hub). If the cable is attached but the problem persists, try a different cable. The maximum allowable distance from adapter to hub is 100 meters.

If you’re directly connecting two computers (no hub), use a crossover cable. Most hubs require a straight-through cable, while most switches require a crossover cable (see your hub or switch documentation to verify).

See the Cabling Information README file for more information on cross- over cables.

Check the LED lights on the adapter.

The EtherExpress PRO/100 TX PCI adapter has three diagnostic LEDs above the cable connector. These lights help indicate if there’s a problem with the connector, cable, or hub. The table on the next page describes the LEDs.
