254 Troubleshooting
Troubleshooting a NIC
1
Restart the compute sled and check for any system messages pertaining to
the NIC controller.
2
Check the appropriate indicator on the NIC connector. See "NIC Indicator
Codes" on page20.
• 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 auto-negotiation 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 NIC ports are
enabled. See "Using the System Setup Program" on page67.
5
Ensure that the NICs, hubs, and switches on the network are all set to the
same data transmission speed. See the documentation for each network
device.
6
Ensure that all network cables are of the proper type and do not exceed the
maximum length.
If all troubleshooting fails, see "Getting Help" on page 289.
