Troubleshooting a NIC
Problem
• NIC cannot communicate with network.
Action
1 Run the appropriate online diagnostic test. See "Using Server Administrator Diagnostics" in
"Running System Diagnostics."
2 Check the appropriate indicator on the NIC connector. See "NIC Indicator Codes" in
"Indicators, Codes, and Messages."
•
If the link indicator does not light, check all cable connections.
• 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 NIC's documentation.
• Change the autonegotiation setting, if possible.
• Use another connector on the switch or hub.
If you are using a NIC card instead of an integrated NIC, see the documentation for the NIC
card.
3 Ensure that the appropriate drivers are installed and the protocols are bound. See the NIC's
documentation.
4 Enter the System Setup program and confirm that the NICs are enabled. See "Using the
System Setup Program" in your User's Guide.
5 Ensure that the NICs, hubs, and switches on the network are all set to the same data
transmission speed. See the network equipment documentation.
6 Ensure that all network cables are of the proper type and do not exceed the maximum length.
See "Network Cable Requirements" in your User's Guide.
