Troubleshooting a NIC
Problem
• NIC cannot communicate with network.
Action
1
Run the appropriate online diagnostic test. See "Using Dell PowerEdge
Diagnostics" on page 117.
2
Check the appropriate indicator on the NIC connector. See "NIC Indicator
Codes" on page 19.
• 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.
