ABSTRACT:
A method for powering a system is described. The method includes receiving a signal that indicates availability of a primary power source to supply operating power to a plurality of computing devices, and responsive to the received signal, transitioning each of the plurality of computing devices from a secondary power source to receiving power from the primary power source after a delay time that is a function of a substantially unique seed value for each computing device.
