6 Testing the Network Adapter

Diagnostics Program

The network adapter can be tested with the supplied diagnostics program (running on DOS). During
testing the link of the tested port will be down, i.e. no data can be transferred.
The following 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 loopback:
All components are tested, including the port.

Loopback Wrap Plug Test

To perform the loopback wrap plug test, you will need a wrap plug (see figure 6 “Setup for loopback
wrap plug testing”).
Alternatively, the loopback test can be performed from port to port (for dual adapters only) or via ex-
ternal repeater. Loopback testing via external repeater requires another adapter installed in a sec-
ond computer running in repeater mode (also see section “Loopback Repeater Test”). The following
procedure describes the test via wrap plug.

During testing, observe the safety precautions given in chapter “Safety Precautions”.
If the fiber adapter is not connected immediately to the data network, insert the protective plug for
safety reasons (otherwise laser light may be emitted) and as a protection against dust and dirt.

The tests do not run in a Windows DOS box.
