Usage guidelines
If PSE power management is disabled, the system does not supply power to new PSEs when PoE
power overload occurs.
If PSE power management is enabled, when PSE power overload occurs, the system supplies
power to a PSE with higher priority. For multiple new PSEs with the same priority, the PSE with a
smaller ID gets power supplied first.
For example, if PoE is enabled for a PSE, and the PSE has higher priority, the system performs the
following operations:
•
Stops supplying power to a PSE with lower priority.
•
Supplies power to the PSE that has higher priority.
This command is only available for the default MDC. For more information about MDCs, see

Technologies Configuration Guide
