Running the Echo Test

After you’ve confirmed that the OfficeConnect NIC is functioning correctly by running the NIC self-tests (as described in the previous section), verify that the NIC is transmitting and receiving data over the network by running the Echo test.

The Echo test checks the ability of the NIC to transmit and receive data while it’s connected to the network.

To run the Echo test, you need two PCs networked together.

■The first PC is used to send data. This is called the sending PC.

■The second PC receives data sent from the first PC. This is called the responding PC.

The two PCs must each have a 3Com OfficeConnect NIC installed. Also make sure that the network driver is installed.

CAUTION: Running the Echo test while connected to an active network with more than two computers can cause intermittent failures within the test. Make sure that only two computers are connected to the network before running the Echo test.
