Troubleshooting Checklist
The following checklist provides recommended actions to resolve problems that
may arise while installing the QL45212 Adapter or running it in your system.
Inspect all cables and connections. Verify that the cable connections at the
network adapter and the switch are attached properly.
Verify the adapter installation by reviewing “Installing the Adapter” on
page 8. 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.
Verify 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 then run the tests
again. If the adapter passes the tests in the new system, the original system
may be defective.
Remove all other adapters from the system, and then run the tests again. If
the adapter passes the tests, the other adapters may be causing contention.
Before you open the server cabinet to add or remove the adapter, review
“Safety Precautions” on page 7.
