Running the Echo Test

Run the Echo test to test the ability of the NIC to transmit and receive data while it is connected to the network. To run the Echo test, you need two PCs networked together. In addition, the two PCs must each have a 3Com NIC installed. Also make sure that the network driver is installed. The first PC is used to send data; the second PC receives the data sent from the first PC.

CAUTION: Running the Echo test while connected to an active network can cause intermittent failures within the test.
