It is configured to be F-enabled. DC module 21-25
When the AC power cutoff is detected, the switches are sequentially switched from the ON state to the OFF state in a predetermined order. The unit for the DC module switched to the OFF state is stopped and does not consume power. Therefore, as the number of power supply modules set to the OFF state increases, the power consumption of the entire computer system gradually decreases.
