Power failure monitoring device and power failure monitoring method

Abstract

A power failure monitoring method applied to a programmable logic device includes outputting a power supply enable signal to instruct a power supply to power on, starting a counter, determining whether a first abnormal power status indication signal exists for each power supply before a current reading of the counter reaches a preset value, and in response that the first abnormal power status indication signal exists, outputting a first read notification signal according to the first abnormal power status indication signal, so that a baseboard management controller reads the first abnormal power supply status indication signal according to the first read notification signal and generates a corresponding power status log.
