Troubleshooting Chart

The following table lists symptoms, possible causes, and possible solutions for problems that might occur.
Table 6. Troubleshooting chart
Symptom
Power LED is off.
Cloud Connection LED is off.
A combined speed and activity
LED or an individual speed LED
and an individual activity LED
are off when the port is
connected to a device.
File transfer is slow or
performance is degraded.
A segment or device is not
recognized as part of the
network.
A combined speed and activity
LED or an individual speed LED
and an individual activity LED
are blinking continuously on all
connected ports and the
network is disabled.
Possible Cause
Power is not supplied to the switch.
The switch is not connected to the
Internet or is not yet discovered and
activated through the NETGEAR
Insight app.
Port connection is not working.
One possible cause is that a
broadcast storm occurred and that a
network loop (redundant path) was
created.
One or more devices are not properly
connected, or cabling does not meet
Ethernet guidelines.
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 and that you discover and add the
switch to your network by using the NETGEAR
Insight app.
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 local browser interface, you can configure
the Spanning Tree Protocol (STP) to prevent
network loops.
Verify that the cabling is correct.
Make sure that all connectors are securely
positioned in the required ports. It is possible
that equipment was accidentally disconnected.
