What happens if the PoE devices need more than the 64W budget?

The TL-SG1008P uses intelligent power management. If the combined PoE demand exceeds the available budget, power to lower-priority PoE ports can be removed so that higher-priority powered devices remain supplied.

The practical solution is to plan the connected devices so their expected requirements fit comfortably within the 64W budget rather than relying on overload management as normal operation.
