DFE-500TX Ethernet PC Card User's Guide
In the Controller Loopback test, test signals are generated at the rate of 100Mbps, and are intercepted and reflected at the MAC level without reaching the network cable.
The Serial ROM Verification, Controller Internal Loopback test, and Twister Layer Loopback test should all show the result “Pass,” irrespective whether a loopback cable is in place. This concludes the Adapter Basic Diagnostic test. If the results are normal, then go ahead to the Network Diagnostic test, starting with Step 4.
Network Operation Test
4.If you have access to a second station on the LAN, then skip ahead to Step 5. If you do not have access to a second station on the LAN, then the network test will be limited to “blind” transmission of test packets (none of which will be returned to the primary station). Follow the cues at the foot of the screen to select and run the Network Diagnostic program. Observe the “Packets Transmitted” line to see that the “Packets Transmitted” line reports a steadily and rapidly increasing packet count. This will indicate normal transmission onto the LAN, and will be the end of your Verification/Diagnostic run. Skip the remaining steps shown below.
