Troubleshooting Your System
Troubleshooting a NIC
Problem
• NIC cannot communicate with network.
Action
1
Run the appropriate online diagnostic test. See "Using Dell PowerEdge Diagnostics" on page 113.
2
Check 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.
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" on page 27.
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.
