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.
