Dell 1600SC manual Inside the System, Troubleshooting a NIC

If the problem is resolved, you must replace the USB device (see "Getting Help").

If the problem persists, see "Getting Help."

Troubleshooting a NIC

Problem

•NIC cannot communicate with network

•NIC cable

•NIC, hub, and switch configuration settings

Action

1.Check the appropriate indicator on the NIC connector (see Figure 2-7). • 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 deleted.

Check the drivers, and remove and reinstall the drivers if applicable. You must reboot your system for the reinstalled drivers to become active.

•Try changing the auto-negotiation setting, if possible.

•Try 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.

2.Ensure that the appropriate drivers are installed and the protocols are bound.

3.Enter the System Setup program and confirm that the NIC is enabled (see "Using the System Setup Program" in your User's Guide).

4.Ensure that the NIC, hubs, and switches on the network are all set to the same data transmission speed.

5.Ensure that all network cables are of the proper type and do not exceed the maximum length.

For more information, see "Network Cable Requirements."
