Troubleshooting a Serial I/O Device

1 Turn off the system, including any attached peripherals, and disconnect

the system from the electrical outlet.

2 Swap 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.

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

comparable device.

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."

Troubleshooting a NIC

1 Run the appropriate online diagnostic test. See "Using Dell™ Diagnostics."
2 Restart the system and check for any system messages pertaining to the

NIC controller.

3 Check the appropriate indicator on the NIC connector. See "NIC Indicator

Codes."

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.

Use another connector on the switch or hub.

If you are using a NIC card instead of an embedded NIC, see the
documentation for the NIC card.

4 Ensure that the appropriate drivers are installed and the protocols are

bound. See the NIC's documentation.

5 Enter the System Setup program and confirm that the NIC ports are

enabled. See "Integrated Devices Screen."

6 Ensure that the NICs, hubs, and switches on the network are all set to the

same data transmission speed and duplex. See the documentation for each
network device.
