4 Turn on the system and the serial device.
If the problem is resolved, replace the serial device.
If the problem persists, see "Getting Help" on page 246.
Troubleshooting a NIC
1 Restart the system and check for any system messages pertaining to the
NIC controller.
2 Check the appropriate indicator on the NIC connector. See "NIC
Indicators (BMC Management Port)" on page 21.
• 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 page 46.
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 246.
