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. The LED to the right of
the connector for the port will be off if no PoE power is delivered, solid green if PoE
power is delivered, or solid yellow if a PoE fault occurs. A PoE fault occurs and PoE
halts because of one of the conditions listed in the following table.
Table 8. PoE fault conditions and possible solutions
PoE Fault Condition
A PoE-related short circuit occurred on the port.
The PoE power demand of the PD exceeded the maximum level that the
switch permits. The maximum level is 15.4W for a PoE connection, 30W
for a PoE+ connection, and 60W for a PoE++ connection.
The PoE current on the port exceeded the classification limit of the PD.
The PoE voltage of the port is outside the range that the switch permits.
Troubleshooting
Guide
Possible Solution
The problem is most likely with the
attached PD. Check the condition
of the PD or restart the PD by
disconnecting and reconnecting
the PD.
Restart the switch to see if the
condition resolves itself.
