Troubleshooting chart

The following table lists symptoms, possible causes, and possible solutions for problems
that might occur.
Table 4. Troubleshooting chart
Symptom
The Power/Cloud LED is off.
The Power/Cloud LED does
not turn blue.
Note: If the switch is a
standalone switch that you
manage through the local
browser interface, the LED
remains green.
The left port LED is off when
the port is connected to a
powered-up device.
A file transfer is slow or
performance is degraded.
Troubleshooting
Possible Cause
Power is not supplied to the switch.
The switch is an Insight managed
switch that is not yet connected to
the cloud server.
The port connection is not working.
One possible cause is that a
broadcast storm occurred and that
a network loop (redundant path)
was created.

Possible Solution
• Check the power cable connections at the
switch and the power source.
• Make sure that all cables are used correctly
and comply with the Ethernet
specifications.
• Make sure that the switch is connected to
the Internet.
• Make sure that you discover and add the
switch to your network by using the
NETGEAR Insight app or the NETGEAR
Cloud portal.
• Check the crimp on the connectors and
make sure that the plug is properly
inserted and locked into the port at both
the switch and the connecting device.
• Make sure that all cables are used correctly
and comply with the Ethernet
specifications.
• Check for a defective port, cable, or
module by testing them in an alternate
environment where all products are
functioning.
Break the loop by making sure that only one
path exists from any networked device to any
other networked device. After you connect
to the switch local browser interface, you can
configure the Spanning Tree Protocol (STP)
to prevent network loops.
