Testing the 3C589D PC Card
Follow these steps to run the PC Card diagnostic program to test the PC Card and the setup:
1Check that the adapter is installed and connected to the network, as described in Chapter 2.
2Boot the computer under DOS.
3Place the EtherDisk diskette in a floppy disk drive on your PC and make that drive the active drive. For example, type:
a:install [Enter]
The main menu appears.
4Select Configuration and Diagnostic program. The Echo Exchange Window appears.
The Echo Exchange Test tests the adapter’s ability to transmit and receive data while on the network.
To run this test on the network, you need another PC set up as an echo server to receive packets from the adapter being tested and echo them back to the adapter.
The PC being used as an echo server must have a 3Com adapter running at the same speed as the 3Com adapter.
CAUTION: Running the Echo Exchange test while connected to an active network can cause intermittent failures. To avoid failures, connect to an inactive network on which only the computer being tested is operating.
5On the echo server PC, select Respond Start and press [Enter].
6On your PC, select Start Test and press [Enter].
7When the test is done, proceed as follows:
a End the program on the echo server computer.
b On the computer with the adapter that you tested, exit the Configuration and Diagnostic Program and reboot the computer.
If a test fails, the adapter may not be defective. The problem may be incorrect option settings, option settings that conflict with the settings of other boards, or improper installation.
