Abstract: A system may include a rack that is configured to receive electrical power from a power distribution box and to distribute the electrical power to one or more electrical loads. The system may include at least one power strip having a first circuit and a second circuit that are mounted in the rack. The first circuit may include outlets into which the electrical loads are connected and a first portion of a connector interface. The second circuit may include an enclosure that houses an electrical configuration including at least one power cord that is coupled to the power distribution box and a second portion of the connector interface that is configured to couple the second circuit to the first circuit by mating with the first portion of the connector interface, where the second circuit is removable from the rack and interchangeable with other second circuits that comprise different electrical configurations.

Abstract: The subject matter of this specification can be embodied in, among other things, a system that includes a computer device. The computer device includes a power supply and a component that receives power from the power supply through a first electrical connection. The system includes a measurement adapter for measuring an electrical property of the first electrical connection. The measurement adapter is interposed within the first electrical connection between the power supply and the component. The measurement adapter is configured to draw power from a second electrical connection that is different from the first electrical connection. The measurement adapter includes a sensor for measuring the electrical property of the first electrical connection.

Abstract: Apparatus and associated method and computer program products involve a highly efficient uninterruptible power distribution architecture to support modular processing units. As an illustrative example, a modular processing unit includes an corresponding uninterruptible power system in which only one AC-to-DC rectification occurs between the utility AC grid and the processing circuit (e.g., microprocessor) loads. In an illustrative data center facility, a power distribution architecture includes a modular array of rack-mountable processing units, each of which has processing circuitry to handle network-related processing tasks. Associated with each modular processing unit is an uninterruptible power supply (UPS) to supply operating power to the network processing circuitry. Each UPS includes a battery selectively connectable across a DC bus, and a AC-to-DC rectifier that converts an AC input voltage to a single output voltage on the DC bus.

Abstract: A system is described that includes a power conversion module, a data port, a controller to receive data from the data port, and a data store containing instructions that when executed by the controller perform operations to control the power conversion module. The operations include executing instructions in a first portion of the data store during booting of the controller, executing instructions in a second portion of the data store after the controller has booted, receiving a signal from the data port indicating the instructions in the second portion are to be modified, receiving from the data port modified instructions to be stored in the second portion, and executing, in response to the signal, the instructions in the first portion to store the modified instructions in the second portion.

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.
