Troubleshooting a Network Adapter
Problem
l Network adapter cannot communicate with network.
Action
1. Run the appropriate online diagnostic test. See " Using Server Administrator Diagnostics " in "Running System Diagnostics."
If the tests fail, continue to the next step.
2. Check the appropriate indicator on the NIC connector. See Table 2 -2 in "Indicators, Messages, and Codes."
l If the link indicator does not light, check all cable connections.
l If the activity indicator does not light, the network driver files might be damaged or missing.
Remove and reinstall the drivers if applicable. See the network adapter's documentation.
l Change the autonegotiation setting, if possible.
l Use another connector on the switch or hub.
3. Ensure that the appropriate drivers are installed and the protocols are bound. See the network adapter's documentation.
4. Enter the System Setup program and confirm that the network adapters are enabled. See "Using the System Setup Program" in your User's Guide.
5. Ensure that the network adapters, hubs, and switches on the network are all set to the same data transmission speed. See the network equipment
documentation.
