Testing the Network Card You can test the network card with the aid of the diagnostics program supplied (running on DOS).
The available test modes are as follows:
• Simple test without loopback: this test covers all the components but not the port (socket incl.
components for transmitting/receiving the data signals).
• Comprehensive port testing with loopback: all the components are tested, including the port.
• For dual link network cards there is also a port-to-port test, comprehensive testing of the network
card including the two ports. For the purposes of the test, the ports are interconnected via a data
cable.
Notes: The tests do not run in a Windows NT DOS box. For Loopback test of the SK-NET GE-T
types, refer to the following paragraph.
You will need the following equipment:
