Table 4-1. Troubleshooting Chart (continued)
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 in working condition and the 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, remove
the AC power from the switch and then reapply AC power. 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.
4-2
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, December 2005
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.
