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.
Claims12
A power failure monitoring method applicable to a programmable logic device, the power failure monitoring method comprising:
- outputting a power supply enable signal, the power supply enable signal used to instruct at least one power supply to power on;
- starting a counter;
- determining whether a first abnormal power status indication signal exists before a current reading of the counter reaches a preset value for each power supply, the first abnormal power status indication signal existing when a falling edge of the power status indication signal exists;
- outputting a first read notification signal according to the first abnormal power status indication signal in response that the first abnormal power status indication signal exists, and 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;
- determining whether a second abnormal power status indication signal exists according to the power status indication signal after the current reading of the counter reaches the preset value;
- and
- outputting a second read notification signal according to the second abnormal power supply status indication signal in response that the second abnormal power supply status indication signal exists, and the baseboard management controller reads the second abnormal power status indication signal according to the second read notification signal and generates a corresponding power status log.
A non-transitory storage medium having stored thereon instructions that, when executed by at least one processor of an electronic device, causes the at least one processor to execute instructions of a power failure monitoring method, the method comprising:
- outputting a power supply enable signal, the power supply enable signal used to instruct at least one power supply to power on;
- starting a counter;
- determining whether a first abnormal power status indication signal exists before a current reading of the counter reaches a preset value for each power supply, the first abnormal power status indication signal existing when a falling edge of the power status indication signal exists;
- outputting a first read notification signal according to the first abnormal power status indication signal in response that the first abnormal power status indication signal exists, and 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;
- determining whether a second abnormal power status indication signal exists according to the power status indication signal after the current reading of the counter reaches the preset value;
- and
- outputting a second read notification signal according to the second abnormal power supply status indication signal in response that the second abnormal power supply status indication signal exists, and the baseboard management controller reads the second abnormal power status indication signal according to the second read notification signal and generates a corresponding power status log.
