摘要:
A power distribution system includes a plurality of loads and a plurality of power sources. The power distribution system also includes an interconnect arrangement including a plurality of interconnects. The interconnects connect each load to a given number of different ones of the sources so that each load is fully powered notwithstanding failure of any one of the sources.

One aspect of the present invention provides a server card that is removably insertable into a server chassis. An electronic power switching mechanism is disposed on the server card and is configured to cause three power states of the server card including a fully operational state, a standby state, and a fully shutdown state. In the fully operational state, a system power of the server card is enabled and a standby power of the server card is enabled. In the standby state, a system power of the server card is disabled and the standby power of the server card is enabled. In a shutdown state, the system power of the server card is disabled and the standby power of the server card is disabled.

A device and method are provided for reducing impedance, impedance discontinuities, and signal-loop area in flex cables used for a signal path. In one embodiment of the invention, a flex cable is provided for reducing the impedance and length of a return-signal path. The flex cable includes a signal conductor, and a return-signal conductor not connected to ground. The flex cable may also include a ground conductor. Such a flex cable provides a shorter- and lower-impedance return-signal path between a signal source and receiver than do conventional flex cables. In another embodiment of the invention, a method is provided that includes the steps of delivering a signal from a signal source to a signal receiver with a flexible conductor, and returning the signal from the signal receiver to the signal source with another flexible conductor other than ground.

A short card support for supporting a short printed circuit card insertable into an electronic system is disclosed. The short card support has a card guide end adapted to couple to the card guide of the electronic system and a card receptor end adapted to couple with a first edge of the short printed circuit card. A support span between the card guide end and the card receptor end permits the short card support to accommodate varying lengths of short printed circuit cards.

A multi stage mounting printed circuit board system and method is presented. In one embodiment, a multi stage mounting printed circuit board system includes a first printed circuit board for mounting electrical components on. A first printed circuit board interface component is coupled to the first printed circuit board. The first printed circuit board interface component communicatively couples the first printed board to a second printed board via a second printed circuit board interface component. A plurality of printed circuit board extractors are coupled to the first printed circuit board. The plurality of printed circuit board extractors couple the first printed circuit board to card guides (e.g., a single pair of card guides in which the second printed circuit board is mounted).
摘要:
Described are devices for cooling a component, and methods thereof. The device includes a base that can be coupled to the component so that heat is transferred from the component to the base. The device also includes fins coupled to the base. The fins are arranged to funnel air from an air intake end of the device toward a location on the base.
摘要:
A power supply comprises a chassis, a plurality of alternating current (AC) power receptacles formed into the chassis, and power supply circuit contained within the chassis and selectively coupled to ones of the plurality of AC power receptacles.
摘要:
A power system provides for redundant input power sources. The power system includes a plurality of inputs that are connectable to a plurality of input sources and an OR circuit coupled to the source inputs. The OR circuit ORs the input sources to provide a source voltage. The power control circuit that is responsive to sufficient source voltage and other commands provides a working voltage to mid- and low-rail converters to provide supply voltages for use by a load.
摘要:
A thermal dissipation apparatus for implementing chassis conducted cooling for a server. The apparatus includes a heat sink having a first surface and a second surface. The first surface is adapted to accept a chip thermal interface for a chip. The second surface is adapted to accept a chassis thermal interface for a chassis surface, wherein the second surface implements a thermal conductive path from the chip to the chassis surface.
