Abstract
A method of powering on a plurality of devices includes identifying a plurality of power distribution units disposed in a rack, wherein each power distribution units is connected to receive power from a main power source, and wherein each power distribution unit includes a circuit breaker. The method further includes identifying a plurality of devices disposed in the rack, wherein each device is connected to receive power from one of the power distribution units, and wherein the plurality of devices are selected from server nodes, network switches and external data storage devices. For each of the power distribution units, the plurality of devices that are connected to the power distribution unit are powered on in a sequence to prevent an inrush current from tripping the circuit breaker within the power distribution unit. The sequence powers on the devices identified as network switches and external data storage devices prior to powering on the devices identified as server nodes.
