GS700TPS Smart Switch
Table A-1. Troubleshooting Chart
Symptom
ACT LED is flashing
continuously on all
connected ports and the
network is disabled.
A unit is linked to a stack,
but does not join the
stack.

Additional Troubleshooting Suggestions

If the suggestions in Troubleshooting Chart do not resolve the problem, refer to the
troubleshooting suggestions in this section.

Network Adapter Cards

Ensure the network adapter cards installed in the PCs are functioning correctly and the latest
software driver has been installed.
Configuration
If problems occur after altering the network configuration, restore the original connections and
determine the problem by implementing the new changes, one step at a time. Ensure that cable
distances, repeater limits, and other physical aspects of the installation do not exceed the Ethernet
limitations.

Switch Integrity

If required, verify the integrity of the switch by resetting the switch. To reset the switch,
disconnect the AC power from the switch and then reconnect AC source. If the problem continues,
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.
A-2
Cause
A network loop
(redundant path) has
been created.
The stacking ports of the
new unit are configured
differently from the stack,
or the unit is configured
as a stand-alone unit.
v1.0, April 2009
Solution
Break the loop by ensuring that there is only one
path from any networked device to any other
networked device.
Remove the unit from the stack. If the stack links are
copper links, push the "Restore to Default" button. If
the stack links are combo links, use the Web
Management to configure the unit as a stackable
unit, with combo links used as the stacking ports.
