Using the 3Com DOS Diagnostics Program

Running the Group 3 Tests
The Group 3 tests verify the ability of the NIC to send and
receive data on the network. Group 3 consists of two tests:
■
Transmit/Receive Test
■
Echo Server Test
Running the Transmit/Receive Test
The Transmit/Receive Test checks the ability of the NIC
to exchange packets with another computer. To run
the Transmit/Receive Test, two PCs with 3C985B-SX
server NICs installed are required: one PC to transmit data
and one PC to receive data.
CAUTION:
Running the Transmit/Receive Test while
connected to an active network can cause intermittent
failures. To avoid this, connect to an inactive network
on which only the PCs being tested are operating.
To run the Transmit/Receive Test:
1 Make sure that a 3C985B-SX server NIC is installed in
the transmitting PC and connected to the network.
2 Install a 3C985B-SX server NIC in another PC (the
receiving PC) and connect it to the network.
3 Launch the DOS diagnostics program on both PCs.
