Configuring PoE Over-Temperature Protection on the Switch
If this function is enabled, the switch disables the PoE feature on all ports when its internal temperature
exceeds 65°C (149°F) for self-protection, and restores the PoE feature settings on all its ports when the
temperature drops below 60°C (140°F).
