A-2 Troubleshooting

v1.0, January 2007

Additional Troubleshooting Suggestions

If the suggestions in Table A-1 do not resolve your problem, refer to the troubleshooting

suggestions in this section.

Network Adapter Cards

Ensure that the network adapter cards installed in the PCs are in working condition and their most

recent software drivers have been installed.

Configuration

If problems occur after altering the network configuration, restore the original connections and

attempt to isolate the problem by implementing the most-recent changes, one step at a time. Make

sure that cable distances, repeater limits, and other physical aspects of the installation do not

exceed the Ethernet specification limitations.

Switch Integrity

If required, verify the integrity of the switch by resetting it. To do this, use the Tools> Reset

command or remove AC power from the switch and then reapply it. If the problem persists,

contact NETGEAR technical support. In North America, call 1-888-NETGEAR. If you are outside

of North America, please refer to the support information card included with your product.
