Troubleshooting Checklist
The following checklist provides recommended actions to take to resolve problems
installing the Gigabit Ethernet NIC or running it in your system.
■
Inspect all cables and connections. Verify that the cable connections at the Gigabit
Ethernet NIC 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.”
■
Check the NIC installation by reviewing “Installing the Hardware.” Make sure that the
NIC 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 are in conflict with
another device.
■
Make sure that your system is using the latest BIOS.
■
Try inserting the NIC in another slot. If the new position works, the original slot in
your system may be defective.
■
Replace the failed NIC with one that is known to work properly. If the second NIC
works in the slot where the first one failed, the failed NIC is probably defective.
■
Install the NIC in another functioning system and run the tests again. If the NIC
passed the tests in the new system, the system may be defective.
■
Remove all other NICs from the system and run the tests again. If the NIC passes the
tests, other NICs may be causing contention.
