Running the Group 3 Test
The Group 3 test (Echo Exchange Test) tests the adapter’s
ability to transmit and receive data while on the network.
To run the Group 3 test on the network, you need a second
computer set up as an echo server. The echo server receives
packets from the adapter being tested and echoes them
back to the adapter.
The second computer must contain a 3Com adapter running
at the same speed as the Fast EtherLink 10/100BASE-T4 PCI
adapter (10 Mbps or 100 Mbps). The diagnostic program
that comes with the Fast EtherLink PCI adapter supports the
EtherLink III echo server diagnostic program.
