Abstract: A power system for multi-input devices with shared reserve power includes a first automatic transfer switch (ATS) and a second ATS each coupled at respective inputs to a primary power system and a reserve power system. An output of one of the ATSs is coupled to first power input of a multi-input electrical device and an output of the other ATS is coupled to a second power input of the multi-input electrical device. When primary power is available, electrical power is fed to both the inputs of the multi-input electrical device and when primary power is not available reserve power is fed to both inputs of the multi-input electrical device. If a component fails between the primary and/or reserve power system and the multi-input electrical device, a full load of the multi-input electrical device is fed from a non-affected one of the inputs of the multi-input electrical device.

Abstract: An external power supply containment unit includes a chassis configured to mount to a structure external to a rack. The external power supply containment unit further includes one or more discrete power supplies mounted in the chassis and one or more electrical connectors that are configured to couple and decouple with a power distribution system of a rack positioned adjacent to the external power supply containment unit. The electrical connectors are configured such that racks of electrical devices, such as computers, can be replaced while the external power supply containment unit remains mounted to the external structure. Additionally, discrete power supply units included in the external power supply containment unit may be re-used to provide power to electrical devices included in a replacement rack when a rack of electrical devices coupled with the external power supply containment unit is replaced.

Abstract: A power distribution system that distributes power to electrical loads includes a switchgear apparatus that selectively routes power from one of two or more feeds to downstream portions of the system based upon commands received from a separate external switchgear controller device that receives data from various portions of the power distribution system. The switchgear controller device can operate in one or more separate operating modes, where commands to the switchgear apparatus are generated based upon user inputs or determinations made by an internal switchgear control module based at least in part upon the selected operating mode of the switchgear controller device. The operating mode can be set based upon user interaction with an operating mode interface. The switchgear control module may generate switchgear operation commands based at least in part upon data received from the switchgear apparatus and various portions of the power distribution system.

Abstract: Techniques are described for managing power in a computing system using power controller(s). Power consumption information may be received from power sensors that measure power consumption of computing devices in a rack computing system, or that measure the power received or distributed by power distribution components such as power distribution units (PDUs) in the racks. A determination may be made whether the amount of power being currently consumed within a computing system exceeds a predetermined threshold. If so, control signal(s) may be sent to instruct the power controller(s) to alter characteristic(s), such as frequency, voltage, current, and so forth, of the power being supplied to one or more computing devices or other component(s). The power alteration may occur at one or more points in the power distribution system of one or more racks, such as at one or more PDUs, distribution circuits, breakers, and so forth.

Abstract: A switchgear controller device that generates commands to a switchgear apparatus that selectively routes power from one of two or more feeds to an electrical load of a power distribution system based upon the commands includes a user interface that displays graphical representations of various portions of the power distribution system. The switchgear controller device can receive data from components included in respective upstream portions and downstream portions of the power distribution system and generates graphical representations of present configurations of the components based at least in part upon the received data. Graphical representations of components included in the downstream portion of the system may be non-interactive, and graphical representations of components included in the upstream portion may be interactive based at least in part upon the present operating mode of the switchgear controller device.

Abstract: A transceiver front-end having a plurality of signal paths operatively connected to at least two electrically separated antennas for transmitting and receiving communication signals in a plurality of frequency bands in GSM and W-CDMA modes. If the frequency band of one signal path is partially overlapping with the frequency band of another signal path, these two signal paths are connected to two different antennas. As such, some of the switching components and matching elements in the transceiver front-end can be eliminated. As a result, the reception loss can be reduced.
