Patent ID: 8742624

Claim:
A method comprising: activating, by a device, a particular power supply, the particular power supply being part of a power module comprising a plurality of power supplies; determining, by the device, that the power module is not running at a new voltage; determining, by the device and based on determining that the power module is not running at the new voltage, that the power module includes enough power supplies to supply power to a plurality of devices at the new voltage; and performing, by the device and based on determining that the power module includes enough power supplies to supply power to the plurality of devices at the new voltage, a stepwise ramp up process, from an old voltage to the new voltage, on the particular power supply, performing the stepwise ramp up process including: ramping up, by the device, the particular power supply from the old voltage to the new voltage; determining, by the device and based on the particular power supply being associated with a voltage that is less than a voltage associated with at least one other power supply of the plurality of power supplies, that the particular power supply is a new power supply; and performing, by the device and based on determining that the particular power supply is the new power supply, the stepwise ramp up process on the particular power supply when there is no mismatch between a set voltage associated with the particular power supply and a measured voltage associated with the particular power supply.
