Troubleshooting PoE
Failure to set the priority of a PI to critical
Symptom
Power supply priority configuration for a PI failed.
Analysis
Possible reasons include:
• The guaranteed power remained for the PI is less than the maximum power required by the PI.
• The priority of the PI is already set.
Solution
To resolve the problem:
• In the first case, either increase the maximum PSE power or reduce the maximum power of the
PI if the remaining guaranteed power of the PSE cannot be modified.
• In the second case, remove the priority that is already configured.
