Embodiment 1
[0034] like figure 1 As shown, this embodiment provides a PSU abnormal power-down processing system, including CPLD103 (Complex Programmable Logic Device, complex programmable logic device), CPU104, BMC102 (Baseboard Management Controller, baseboard management controller), PCH105 and at least one PSU101 (Power SupplyUnit, power supply).
[0035] Each PSU101 is connected to CPLD103 and BMC102 respectively; BMC102 is connected to CPLD103 and PCH105 respectively; CPU104 is connected to CPLD103 and PCH105 respectively.
[0036] BMC102 detects the total power consumption of all PSU101, according to the total power consumption of PSU101, controls the triggering of CPU104 throttling pin through CPLD103, and sets the upper limit of power consumption of CPU104 through PCH105.
[0037] Specifically, when the total power consumption of the PSU101 is greater than the preset power consumption value of the PSU101, the BMC102 outputs the first signal to the CPLD103, so that the CPLD103 cont...
Embodiment 2
[0042] like figure 2 As shown, this embodiment provides a method for processing abnormal power failure of a PSU based on the system of Embodiment 1. The method includes the following steps:
[0043] S1, BMC102 reads the total power consumption of all PSU101;
[0044] Specifically, BMC102 reads the total power consumption of all PSU101 through the I2C module.
[0045] S2. According to the total power consumption of the PSU101, the BMC102 controls the triggering of the throttling pin of the CPU104 through the CPLD103, and sets the upper limit of the power consumption of the CPU104 through the PCH105.
[0046] The step S2 specifically includes the following processes:
[0047] S2-1, when the total power consumption of PSU101 is greater than the preset power consumption value of PSU101, BMC102 outputs the first signal to CPLD103, so that CPLD103 controls CPU104 throttling pin is not triggered; at the same time, BMC102 will read the current total power consumption of PSU Trans...
Embodiment 3
[0055] Based on the second embodiment, this embodiment provides a device for processing abnormal power failure of a PSU, which is configured on the BMC 102 and includes the following functional units.
[0056] (1) PSU total power consumption reading unit: read the total power consumption of all PSU101.
[0057] The PSU total power consumption reading unit reads the total power consumption of all PSU101 through the I2C module.
[0058] (2) Throttling pin trigger unit: according to the total power consumption of PSU101, control the triggering of CPU104 throttling pin through CPLD103.
[0059] When the total power consumption of PSU101 is greater than the preset power consumption value of PSU101, the throttling pin trigger unit outputs the first signal to CPLD103, so that CPLD103 controls the CPU104 throttling pin not to be triggered, and the power consumption of the whole machine will not drop to the preset value PSU101 power consumption value below.
[0060] When the total po...
