Abstract: A method and apparatus are provided for balancing the load placed by a data center on different phases of a power input. According to the method and apparatus, the load on the power is monitored and a load imbalance detected. Once the load imbalance is detected, a server rack from the data center is selected and a power supply in the selected server rack is reconfigured to output an increased or decreased voltage.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for identifying, for each of multiple circuits of an electrical device, a discharge time that indicates an amount of time previously taken for a voltage level of the circuit to decrease from a normal operating voltage to a specified voltage level after power was removed from the circuit. A delay time period is determined for the electrical device based on each discharge time. A command is received to cycle power to one or more components of the electrical device. In response to receiving the command, power is removed from the circuits for an amount of time that corresponds to the delay time period and power is restored to the circuits in response to the amount of time lapsing.
