Checklist
The following checklist provides recommended actions to take to resolve problems installing
the Gigabit Ethernet Adapter or running it in your system.
Inspect all cables and connections. Check the length and rating of the cable. Make sure
that the cable segment is compliant with the requirements listed in Table 2-2 on page 2-4.
Connect the adapter to a different network port and run the tests again. If the test results
reflect that the adapter is functioning properly, the original network port may be defective
or improperly configured.
Check the adapter installation by reviewing Chapter 2. Make sure that the adapter board is
properly seated in a PCI slot. Check for specific hardware problems, such as broken traces
or loose/broken solder connections.
Check the configuration settings and change them if they are in conflict with another device.
