Troubleshooting a Serial I/O Device

If the problem persists, replace the device.

If all troubleshooting fails, see “Getting Help” on page 343.

1Turn off the system and any peripheral devices connected to the serial port.

2Swap the serial interface cable with another working cable, and turn on the system and the serial device.

If the problem is resolved, replace the interface cable.

3Turn off the system and the serial device, and swap the device with a comparable device.

4Turn 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 343.

Troubleshooting a NIC

1Restart the system and check for any system messages pertaining to the NIC controller.

2Check the appropriate indicator on the NIC connector. See “LAN Indicators (Management Port)” on page 28.

∙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.
