Abstract: A power distribution system, modular data center (MDC), and method provide a permanent electrical enclosure sized for an eventual maximum load allowing for flexible ampacity and concurrent upgradeability. A busway is mountable in a MDC to carry three-phase AC electrical power. A three-phase electrical cable is rated to carry a maximum power value to connect to a power distribution unit (PDU) of a first rack-based information handling system (IHS) of the MDC. A bus plug is engaged to the first busway and has at least three conduction paths that electrically connect to the three-phase electrical cable. Interchangeable fused switch modules of different power ratings are selectable to be received in a fused switch module receptacle in the bus plug. A reduced power fused switch module for initial power capacity of the MDC can later be upgraded to a maximum power rating without changing anything but the fused switch module.

Abstract: There is adopted a shape in which the portions, at the central side of a distribution board, of left and right unit bases on which respective breakers are mounted can be arranged in a staggered manner, so that there is realized a structure in which units can be horizontally arranged while the units share a central vertical bus-line. Alternatively, two insertion-type breakers are horizontally arranged on one and the same unit base and wiring is performed from a contactor provided on the unit base to the primary-side terminal of each of the breakers, so that the left and right breakers share the central vertical bus-line.

Abstract: A locking device for an electric switch is disclosed which is movably guided in a withdrawable rack via an actuating shaft wherein the electric switch is placed in a preferred position, in particular in a disconnected position. In at least one embodiment, the locking device is movable from a release position in which the switch is displaceable in the withdrawable rack to a locking position in which the locking device blocks the switch displacement in a predetermined direction and the actuating shaft is actuated via an actuating crank. In order to safe the switch locking in the preferred position thereof, the locking device is movable to the locking position when the actuating crank actuation is blocked, only. The withdrawable rack, provided with the inventive locking device for the electric switch displaceable in the withdrawable rack via the actuating shaft, is also disclosed.

Abstract: The time required to boot a computer is reduced by reducing or eliminating the need to discover many or all devices within the computer and the machine topology. Access panels are monitored so that it is detected when they are opened. For the access panels that have not been opened, it is assumed that the system configuration, topology, devices, etc. have not changed since the last boot process and there is no need to spend time discovering these devices and machine topology. Stored, instead of discovered, configuration information is then used to configure these devices. This reduces the time required to boot since discovery of devices is not performed. A service processor or other logic may be used to detect which access panels are opened. Also, only those elements of the configuration that may be affected by the particular access panels that were opened need to be re-discovered.

Abstract: A computer enclosure includes a hood (30), a bracket (10) attached to the hood, and a base (60).
