Break the loop by ensuring that only
one path exists from any networked
device to any other networked device.
After you connect to the switch web
management interface, you can
configure the Spanning Tree Protocol
(STP) to prevent network loops.
A network loop (redundant path) was
created.
Combined speed/activity LED or
an individual speed LED and an
individual activity LED are blinking
continuously on all connected
ports and the network is disabled.
Remove the unit from the stack. Use
the web management interface to
configure the unit as a stackable unit,
with combo links used as the stacking
ports.
The stacking ports of the new unit are
configured differently from the stack, or the
unit is configured as a standalone unit.
A unit is linked to a stack but does
not join the stack.
Additional Troubleshooting Suggestions
If the suggestions in the troubleshooting chart do not resolve the problem, see the following troubleshooting
suggestions:
• Network adapter cards. Make sure that the network adapters that are installed in the computers are in
working condition and the software driver was installed.
• Configuration. If problems occur after you alter the network configuration, restore the original connections
and determine the problem by implementing the new 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. If necessary, verify the integrity of the switch by resetting it.To reset the switch,
disconnect the AC power from the switch and then reconnect the AC power. If the problem continues,
contact NETGEAR technical support. For more information, visit the support website at
support.netgear.com.
• Autonegotiation. The RJ-45 ports negotiate the correct duplex mode, speed, and flow control if the
device at the other end of the link supports autonegotiation. If the device does not support autonegotiation,
the switch determines only the speed correctly, and the duplex mode defaults to half-duplex.
The Gigabit Ethernet ports negotiate speed, duplex mode, and flow control if the attached device supports
autonegotiation.
