Troubleshooting PoE

Symptom 1: Unable to set the priority of a PoE interface to critical.
Analysis:
The guaranteed remaining power of the PSE is lower than the maximum power of the PoE interface.
The priority of the PoE interface is already set.
Solution:
In the first case, increase 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.
In the second case, remove the priority already configured.
Symptom 2: Applying a PoE profile to a PoE interface fails.
Analysis:
Some configurations in the PoE profile are already configured.
Some configurations in the PoE profile do not meet the configuration requirements of the PoE
interface.
Another PoE profile is already applied to the PoE interface.
Solution:
In the first case, remove the original configurations of those configurations.
In the second case, modify some configurations in the PoE profile.
In the third case, 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.
