152 | Troubleshooting Your System

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 179.

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 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 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 26.

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 179.
