3Com PC Card Diagnostics Program 3-7
Running the Echo Test
The echo test tests the CardBus PC Card’s ability to
transmit and receive data while on the network.
CAUTION: Running the echo test while connected to an
active network can cause intermittent failures. To avoid this,
connect to a test network on which only the notebook
being tested and the echo server PC are operating.
You need two computers, each with a 3Com network
adapter installed, to run an echo test: one computer to
send data and another to receive data.
This second computer is called the echo server or sending
computer. Make sure it has the same operating system as
the first computer.
Table 3-2 lists the diagnostics programs for the supported
echo server adapters.
To run the echo test, follow these steps:
1 Install the CardBus PC Card, connect it to the network,
and install the network driver.
2 Install a CardBus PC Card in another computer, connect
it to the network, and install the network driver.
