Troubleshooting a Serial I/O Device

port.

system and the serial device.

comparable device.

If the problem is resolved, replace the serial device.

Troubleshooting a NIC

1 Run the appropriate online diagnostic test. See "Using Online Diagnostics"

on page 121.

2 Restart the system and check for any system messages pertaining to the

NIC controller.

3 Check the appropriate indicator on the NIC connector:

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.

See "NIC Indicator Codes" on page 16.
