z
The guaranteed remaining power of the PSE is lower than the maximum power of the PoE
interface.
z
The priority of the PoE interface is already set.
Solution :
z
In the first case, you can solve the problem by increasing the maximum PSE power, or by
reducing the maximum power of the PoE interface when the guaranteed remaining power of the
PSE cannot be modified.
z
In the second case, you should first remove the priority already configured.
Symptom 2 : Applying a PoE profile to a PoE interface fails.
Analysis :
z
Some configurations in the PoE profile are already configured.
z
Some configurations in the PoE profile do not meet the configuration requirements of the PoE
interface.
z
Another PoE profile is already applied to the PoE interface.
Solution :
z
In the first case, you can solve the problem by removing the original configurations of those
configurations.
z
In the second case, you need to modify some configurations in the PoE profile.
z
In the third case, you need to remove the application of the undesired PoE profile to the PoE
interface.
Symptom 3 : Provided that parameters are valid, configuring an AC input under-voltage threshold fails.
Analysis :
The AC input under-voltage threshold is greater than or equal to the AC input over-voltage threshold.
Solution :
You can drop the AC input under-voltage threshold below the AC input over-voltage threshold.
