Abstract
A computer program product includes computer usable program code embodied on a tangible computer usable storage medium for: identifying a plurality of power distribution units (PDUs) disposed in a rack, wherein each PDU receives power from a main power source, and wherein each PDU includes a circuit breaker; identifying a plurality of devices disposed in the rack, wherein each device receives power from one of the PDUs, and wherein the plurality of devices are selected from server nodes, network switches and external data storage devices; and powering on, for each of the PDU, the plurality of devices that are connected to the PDU in a sequence to prevent an inrush current from tripping the circuit breaker within the PDU, wherein 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.
