Table 8. PoE fault conditions and possible solutions
Possible SolutionPoE Fault Condition
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.
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 or
30W for a PoE+ connection.
The PoE current on the port exceeded the classification limit of the PD.
Restart the switch to see if the
condition resolves itself.
The PoE voltage of the port is outside the range that the switch permits.
