Before opening the cabinet of your system for removing or inserting the adapter card, review all precautions outlined under “Reviewing Safety Precautions” on page 23.
Inspect all cables and connections. Verify that the cable connections between the adapter and the switch are attached properly. Make sure that the cable length and rating are compliant with the requirements listed in “Connecting the Network Cables” on page 32."
Check the adapter installation by reviewing Chapter 2, “Installing the Hardware” on page 21.
Make sure that the adapter card 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 are in conflict with another device.
Make sure that your system is using the latest BIOS.
Try inserting the adapter card in another slot. If the new position works, the original slot in your system may be defective.
Replace the failed adapter card with one that is known to work properly. If the second adapter card works in the slot where the first one failed, the original adapter card is probably defective.
Install the adapter card in another functioning system and run the tests again. If the adapter card passed the tests in the new system, the original system may be defective.
Remove all other adapter cards from the system and run the tests again. If the adapter card passes the tests, the other adapter cards may be causing contention.
