4Reconnect and power on each USB device one at a time.

5If a device causes the same problem, power down the device, replace the USB cable, and power up the device.

If the problem persists, replace the device.

If all troubleshooting fails, see "Getting Help."

Troubleshooting a Serial I/O Device

1Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.

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."

Troubleshooting a NIC

1Run the appropriate online diagnostic test. See "Using Dell™ PowerEdge™ Diagnostics."

2Restart the system and check for any system messages pertaining to the NIC controller.

3Check 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.
