Both the internal and external loopback example tests show 1000 packets successfully received with 0 errors
detected, indicating that the NIC hardware is functioning properly.
If the NIC does not perform as expected, try reinstalling the NIC card or moving it to a different slot or to a different
system, then run the DOS Diagnostics tests again. If the card still fails, contact 3Com Customer Support.

Checking the Port LEDs

1000Base-SX Fiber NICs

Two port LEDs are located on the faceplate of the 1000Base-SX NIC: one to indicate link status and one for data
transfer status (see "1000Base-SX Fiber NICs" on page 9). Before the port LEDs can provide troubleshooting
information, the NIC must be connected to the network (see Chapter 2), and the network drivers for your
particular operating system must be installed (see Chapter 3).
