Abstract

See full text

A method of powering on a plurality of devices includes identifying a plurality of power distribution units (PDUs) disposed in a rack, wherein each PDU receives power from a main power source and includes a circuit breaker. A plurality of devices disposed in the rack are identified, wherein each device receives power from one of the PDUs, and wherein the plurality of devices are server nodes, network switches or external data storage devices. Vital product data (VPD) is obtained from a service processor in each device, wherein the VPD identifies the device by a model identification code. For each PDU, the plurality of devices connected to the PDU are powered on in a sequence to prevent an inrush current from tripping the circuit breaker within the PDU, wherein the sequence powers on devices in order of ascending commonality of the model identification code.
