Running the Group 3 Test
The Group 3 test is called the Echo Exchange Test. It tests the
adapter’s ability to transmit and receive data while on the
network.
CAUTION: Do not use an active network to run the Group 3
test.
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 be equipped with a 3Com
adapter. The diagnostic program that comes with the adapter
supports the 3C590 echo server diagnostic program.
Setting Up an Echo Server
If your echo server contains a 3C590 PCI adapter, select the Echo
Server menu item under the Test menu, and click the <Start>
command button to make the computer an echo server.
If you are setting up an echo server using a 3Com adapter
other than a 3C590 PCI adapter, follow these steps:
1 Select a computer to use as an echo server.
2 Insert the EtherDisk diskette in a floppy drive.
The diagnostic program comes on the EtherDisk diskette that
accompanied the adapter.
