Troubleshooting Checklist
The following checklist provides recommended actions to take to resolve
problems installing the QLogic 8400/3400 Series adapters or running them in your
system.

Inspect all cables and connections. Verify that the cable connections at the
network adapter and the switch are attached properly. Verify that the cable
length and rating comply with the requirements listed in
“Connecting the
Network Cables” on page 11 .

Check the adapter installation by reviewing “Installation of the Network
Adapter” on page 10 . Verify that the adapter is properly seated in the 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 are in conflict with
another device.

Verify that your server is using the latest BIOS.

Try inserting the adapter in another slot. If the new position works, the
original slot in your system may 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 system and run the tests again. If
the adapter passed the tests in the new system, the original system may be
defective.

Remove all other adapters from the system and run the tests again. If the
adapter passes the tests, the other adapters may be causing contention.
