The SG3452XP Switch 2.20 (2.20.5 Build 20241206 Rel. 37607) disables power delivery over the UTP cable due to eddy currents in the UTP cable.
This interruption in PoE power delivery occurs due to voltage surges caused by eddy or direct currents received through the UTP cable.
Perhaps this information can help those experiencing sudden power outages across the PoE PSU.
