Troubleshooting a NIC
Problem
•NIC cannot communicate with network.
Action
1Run the appropriate online diagnostic test. See "Using Dell PowerEdge Diagnostics" on page 97.
2Check the appropriate indicator on the NIC connector.
•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.
3Ensure that the appropriate drivers are installed and the protocols are bound. See the NIC's documentation.
4Enter the System Setup program and confirm that the NICs are enabled. See "Using the System Setup Program" on page 27.
5Ensure that the NICs, hubs, and switches on the network are all set to the same data transmission speed. See the network equipment documentation.
6Ensure that all network cables are of the proper type and do not exceed the maximum length. If the problem persists, see "Getting Help" on page 107.
