Abstract
Examples described herein provide improved power down of PoE interfaces. Examples described herein may set a power fault value for each of a plurality of PSUs, and set a power threshold value for each of a plurality of PoE interfaces. Examples described herein may detect a fault that interrupts a flow of power from a subset of the PSUs to at least one of the PoE interfaces, and based on detecting the fault, for each PSU in the subset of the PSUs, add the power fault value for the PSU to a total power fault value. Examples described herein may, for each of the PoE interfaces, determine whether the total power fault value satisfies the power threshold value for the PoE interface, and based on a determination that the total power fault value satisfies the power threshold value for the PoE interface, power down the PoE interface.
