Troubleshooting a NIC
Problem
• NIC cannot communicate with network.
Action
1 Run the appropriate online diagnostic test. See "Using Dell PowerEdge
Diagnostics" on page 131.
2 Check the appropriate indicator on the NIC connector. See "NIC Indicator
Codes" on page 14.
• 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 29.
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.
If the problem persists,
see "Getting Help" on page 141 .
