In this step, when power supply PMBUS is with server normal communication, the signal of transmission is the alternate timing of low and high level
Signal, when communication failure, signal can become lasting low level or high level, therefore can be according to the characteristic to I2C bus
Level signal detected.
S11: judge the level signal whether within a preset time in low level or high level；
S12: if the level signal is in low level or high level in the preset time, the I2C bus is determined
It is resetted in communication fault state, and to the I2C bus.
As can be seen from the above description, which is detected by the level signal to I2C bus, when the level
Signal is in low level or high level in the preset time, then illustrates that the I2C bus is in communication fault state, at this time
The problem of power supply resets to the I2C bus, communication failure between server and power supply has been solved perfectly.
Optionally, the level signal is clock signal.
Optionally, the level signal is data-signal.
Optionally, the preset time is 35ms.
Further, the level signal for obtaining the I2C bus includes:
The level signal of the I2C bus is obtained according to prefixed time interval.
In this step, such as every 10ms obtains the level signal of the primary I2C bus, detects, realizes to it
