Problems solved by technology

[0002] When the power supply has abnormal problems such as overheating, if the server continues to run at high power consumption, the load on the power supply will increase, which will easily lead to power supply damage, equipment power-off and other problems. In severe cases, the server will be damaged and important data will be lost.

Embodiment 1

[0031] as attached figure 1 As shown, the PMbus of the power supply is connected to the I2C bus of the BMC to realize the communication between the power supply and the BMC. The BMC periodically obtains the information of the status register in the power supply through the PMbus. Once the abnormal information of the power state is detected, the BMC sends the frequency reduction command to the CPU through I2C, so that the CPU runs in a low power consumption state and reduces the power load. After the BMC detects that the abnormal state disappears, it sends a command to the CPU to restore its operating frequency.

Abstract

The invention discloses a universal server power supply protection mechanism. A PMbus of a power supply and an I2C bus of a BMC are connected; through the BMC, the state information of the power supply is acquired in real time; once power supply abnormal information is monitored, the BMC sends a command to enable a CPU to carry out frequency reduction so as to reduce the power supply load; and after the abnormal state disappears, the BMC enables the CPU to restore the normal running state. According to the universal server power supply protection mechanism, the power supply load can be lightened by a universal server when the power supply is abnormal, so that the safe operation of the power supply is ensured, the serious consequences such as power supply damage and server power down can be avoided, the stability of the server is improved and the market competitiveness in the like products is strengthened.

Description

technical field [0001] The invention relates to the field of server power supply, in particular to a general server power supply protection mechanism. Background technique [0002] When abnormal problems such as overheating of the power supply occur, if the server continues to run at high power consumption, the load on the power supply will increase, which will easily lead to power supply damage, equipment power-off and other problems. In severe cases, the server will be damaged and important data will be lost. [0003] The I2C (Inter Integrated Circuit, internal integrated circuit) bus is a bus standard widely used in the field of microelectronics communication control, and is used to connect I2C masters, I2C slaves and other devices. The I2C master is a device that initiates transmission, generates clock signals, and terminates transmission, and can become a device that controls the I2C bus. The I2C slave is a device addressed by the I2C master. [0004] PSUs (power suppl...
