Embodiment Construction
[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0015] A method for reporting a power failure, applied to a host system / remote server system, such as figure 1 As shown, the host system / remote server system includes several power supply units, field programmable logic gate array chips, baseboard management controllers, and Intel management engines. The power supply unit is PSU, the field programmable logic gate array chip is FPGA, the baseboard management controller is BMC, and the Intel management engine is ME.
[0016] The fault alarm pin Alert of each power supply unit is connected to the field programmable logic gate array chip, and when a fault is detected inside the power supply unit, a signal is sent to the field programmable logic gate array chip. The Present pin of each power supply unit is connected with the field programmable logic gate array chip, and is used for timely...
