In single power module, inlet temperature sensor is write the inlet temperature of the power module for gathering by I2C
In corresponding depositor, RMC obtains the inlet temperature in power module corresponding registers, the as inlet temperature of power module.
In the guard method of the power supply inlet temperature monitoring of the present invention, RMC obtains all power module phases of Rack servers
The inlet temperature of inlet temperature sensor feedback is answered, and contrast draws maximum inlet temperature value as standby inlet temperature Tmax,
It is sent to all power modules.When the inlet temperature sensor of a certain power module occurs abnormal, the power module is adopted
Tmax as inlet temperature, as the foundation for adjusting itself rotation speed of the fan of the power module, it is ensured that power supply fan is patrolled according to inside
Collect normal speed governing, it is to avoid internal component excess temperature.When power module inlet temperature normal operation of sensor, power module is still adopted
Power supply fan is adjusted with inlet temperature value Ti, it is ensured that in the case of power module inlet temperature sensor abnormality, power supply
Fan can also be adjusted according to inlet temperature, it is ensured that the normal work of power module.
Preferably, the guard method of the power supply inlet temperature monitoring specifically includes following steps：
S1：RMC obtains the inlet temperature of all power module inlet temperature sensor feedbacks；
S2：All inlet temperature values contrasts of the RMC to obtaining, draws maximum inlet temperature value as standby inlet temperature Tmax,
And it is sent to all power modules；
S3：Power supply FM obtains inlet temperature Ti and standby inlet temperature of the corresponding inlet temperature sensor feedback of each power module
Tmax；
S4：Power supply FM monitorings power module inlet temperature sensor whether normal work, if normal execution step S5, otherwise performs
Step S6；
S5：Power module, as inlet temperature, carries out power supply fan regulation using Ti；
S6：Power module, as inlet temperature, carries out power supply fan regulation using Tmax.
Preferably, the RMC obtains the corresponding inlet temperature sensor feedback of all power modules by PM_Bus agreements
Inlet temperature, and standby inlet temperature Tmax is sent to by all power modules by PM_Bus agreements.
Preferably, power supply FW obtains the standby of the inlet temperature Ti and RMC transmission of inlet temperature sensor feedback by I2C
Use inlet temperature Tmax.
Compared with prior art, the guard method of Rack server power supplies inlet temperature of the invention monitoring has following prominent
The beneficial effect for going out：The guard method of the power supply inlet temperature monitoring of the present invention, RMC obtains all power supplys by PM_Bus agreements
The inlet temperature of the corresponding inlet temperature sensor feedback of module, contrast is carried out to inlet temperature value and show that maximum inlet temperature value is made
For standby inlet temperature Tmax, and all power modules are sent to, when the inlet temperature sensor of power module occurs abnormal,
