Troubleshooting checklist

The following checklist provides recommended actions to take to resolve problems
installing the Netfinity Gigabit Ethernet Adapter or running it in your computer.
• Inspect all cables and connections. Verify that the cable connections at the adapter
and the switch are attached properly. Be sure that the cable length and rating comply
with the requirements listed in "Connecting the network cables" on page 1-6.
• 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 might
be defective or improperly configured.
• Check the adapter installation by reviewing "Installing the Netfinity Gigabit Ethernet
Adapter" on page 1-5. Be sure that the adapter board is properly seated in a PCI slot.
Check for specific hardware problems, such as obvious damage to board components
or the PCI edge connector.
• Check the configuration settings and change them if they conflict with another
device.
• Be sure that your computer is using the latest BIOS.
• Try inserting the adapter in another slot. If if it works in the new position, the original
slot in your computer might be defective.
• Replace the failed adapter with one that is known to work properly. If the second
adapter works in the slot where the first one failed, the original adapter is probably
defective.
• Install the adapter in another functioning computer and run the tests again. If the
adapter passed the tests in the new computer, the original computer might be
defective.
• Remove all other adapters from the computer and run the tests again. If the adapter
passes the tests, the other adapters might be causing the problem.
