Symptom
Power LED is off.

are off when the port is
connected to a device.
File transfer is slow or
performance is degraded.
A segment or device is not

are blinking continuously on all

PoE Troubleshooting Suggestions

Here are some tips for correcting PoE problems that might occur:
• Make sure that the PoE Max LED is off. If the PoE Max LED is solid yellow, disconnect one or more
PoE devices to prevent PoE oversubscription. Start by disconnecting the device from the
highest-numbered port.
• Make sure that the Ethernet cables are plugged in correctly. For each powered device (PD) that is
connected to the switch, the associated right port LED on the switch lights solid green. If the right port
Possible Cause
Power is not supplied to the
switch.
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.
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
web management 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.
