Additional Troubleshooting Suggestions
If the suggestions in Table 4-1 do not resolve your problem, refer to the following
troubleshooting suggestions.
Network Adapter Cards
Make sure that the network adapter cards installed in the PCs are in working
condition and the software driver has been installed.
Configuration
If problems occur after you change the network configuration, restore the original
connections. Then find the problem by making the 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 limitations.
Switch Integrity
You can verify the integrity of the switch by resetting the switch. To reset the
switch, use the Tools> Reset command, or remove AC power from the switch and
then reapply AC power. If the problem continues, contact NETGEAR technical
support. See the Support Information Card that shipped with your product.
A segment or device is
not recognized as part of
the network.
One or more devices are
not properly connected,
or cabling does not meet
Ethernet guidelines.
Verify that the cabling is correct.
Be sure all connectors are
securely positioned in the required
ports. Equipment may have been
accidentally disconnected.
ACT LED is flashing
continuously on all
connected ports and the
network is disabled.
A network loop
(redundant path) has
been created.
Break the loop by ensuring that
there is only one path from any
networked device to any other
networked device.
