6 Testing the Network Adapter

Diagnostics Program

The network adapter can be tested with the supplied diagnostics program (running on DOS). The
diagnostics program runs offline, i.e. normal operation of the network adapter can not b e main-
tained. During testing the link of the tested port will be down, i.e. no data can be transferred. The fol-
lowing tests are available:
• Simple test without loopback:
This test covers all components but not the port (socket including components for transmitting/
receiving the data signals).
• Comprehensive port test with lo opback:
All components are tested, including the port.

Loopback Test for Fiber Adapters

To perform the loopback test on fiber adapters, you will need a loopback connector (see
figure 5 "Setup for loopback testing").

To test the adapter, proceed as follows:
1. Switch off the computer.
2. If the computer is still connected to the data network, unplug the data cable from the network
adapter’s port.

The tests do not run in a Windows NT DOS box.
