A method of cooling a rack of heat dissipating components comprises cooling air, and porting the cooled air into a volume in front of the rack from above the volume. The method further comprises moving the cooled air from the volume in front of the rack to a plenum at a rear portion of the rack to pressurize the plenum. The cooled air is moved with an air mover disposed at a bottom portion of the rack, The method also comprises flowing air from the pressurized plenum past or through heat dissipating components in the rack to the volume in front of the rack, by force of pressure in the plenum through air-directing ports in the plenum. The air may be flowed through the heat dissipating components, around the heat dissipating components, or both. The method further comprises drawing warm air from an upper portion of the volume in front of the racks to cool it again.

Described are seismic-resistant equipment cabinets and door latches for enabling a hinged door to remain attached to the cabinet during a seismic event of a particular intensity. The door has a latch disposed along one edge of the door. The latch includes a latch-keeper receptacle and a latching bolt disposed in the latch-keeper receptacle. The latching bolt is slideable between a latched and an unlatched position. The frame has a latch keeper assembly attached to an edge thereof. The latch keeper assembly is positioned to enter the latch-keeper receptacle when the door latches to the frame. The latch keeper assembly includes a protruding member having a tapered edge and a latching-bolt aperture to receive the latching bolt when in the latched position. The tapered edge establishes a close fit by the latch keeper assembly within the latch receptacle to limit relative motion therebetween during a seismic event.

A data storage interface for coupling data between processors and a bank of disk. The interface includes a plurality of first directors coupled to the processors and a plurality of second directors coupled to the bank of disk drives. A cache memory is coupled between the plurality of first directors and the plurality of second directors. The interface includes a pair of independent power busses. At least one of the first or second directors is coupled to the pair of independent power busses. One portion of the disk drives in the bank is connected to only a first one of the pair of power buses and a different portion of the disk drives is connected to only the other one of the pair of power buses. A power circuit includes a pair of input terminals, each one being electrically connected to a corresponding one of the pair of independent power busses. The circuit includes an output terminal. A pair of switching transistor sections is provided. The transistor switching sections is serially connected between a corresponding one of the pair of input terminals and the output terminal. A logic network is provided for operating the switching sections to prevent current passing into one of the pair of input terminals from one of the power busses from passing into the other one of the power buses. The logic section operates the switching sections to prevent current from one of the pair of power buses to the one of the input terminals connected thereto from exceeding a predetermined value, and operates the switching sections to prevent a difference between a voltage at one of the input terminals and a voltage at the other one of the input terminals from exceeding a predetermined value.

Dual power bus data storage system

An electronic system has electronic equipment (e.g., data storage equipment), and an electronic cabinet assembly which is configured to support the electronic equipment. The electronic cabinet assembly includes a first electronic cabinet frame defining a first set of electronic equipment bays to carry a first portion of the electronic equipment, and a second electronic cabinet frame defining a second set of electronic equipment bays to carry a second portion of the electronic equipment. The electronic cabinet assembly further includes a set of latch subassemblies which is configured to selectively (i) interconnect the first and second electronic cabinet frames, and (ii) disconnect the first and second electronic cabinet frames from each other. Accordingly, a user is capable of conveniently attaching the electronic cabinet frames together using the set of latch subassemblies, and optionally separating the electronic cabinet frames at a later time, without handling any nuts or bolts.

Techniques for interconnecting electronic cabinet frames

An electrical cabinet stores, or houses, a variety electrical components. The electrical components within the cabinet may be interconnected and may be connected to other electrical components external to the cabinet. The cabinet has an access door with a door stop that allows the door to be locked in an open position. The cabinet contains a workstation with a pivoting platform that supports an electrical component. The cabinet has an extendable bracket that extends allows an electrical component to be extended from the cabinet and removed by lifting the component in an upward direction. The cabinet has a board guide module that aligns a circuit board with an electrical connector in the cabinet. The cabinet has a bulkhead connector that reduces electromagnetic degradation in electrical cables that extend from the cabinet.

A fastening device attaches a printed circuit board, such as a backplane, within a support framework of an electrical cabinet. The fastening device includes two adjacent members of the support framework. A threaded stud is attached to one of the members and extends toward the adjacent member. A captive fastener is attached to the other adjacent member. The captive fastener has a thread that cooperates with the thread of the stud. The fastener is aligned with the stud, the cooperative thread of the fastener is capable of engaging the thread of the stud. The fastening device secures the printed circuit board between the adjacent members of the support framework.

A housing receives a printed circuit board and a plurality of daughter boards. The housing has two opposing sidewalls, a floor, and a ceiling. The sidewalls extend from opposing sides of the floor to opposing sides of the ceiling. The opposing sidewalls, the floor and the ceiling defining an opening for receiving a daughter board within slots in the floor and the ceiling. A movable ceiling member attaches to the sidewalls. The ceiling, the movable ceiling member and the sidewalls define an opening for receiving a printed circuit board, such as a backplane, when the movable ceiling member is in an unsecured position. The movable ceiling member is aligned with the ceiling when the movable ceiling member is in a secured position. The movable ceiling member includes a fastener that secures the printed circuit board. The movable ceiling member accommodates printed circuit boards having various thicknesses.

Housing for interconnected printed circuit boards

A stiffener supports a printed circuit board during insertion and removal within a slot of a card cage having one or more electrical connectors. The stiffener has a rigid elongated member that defines an elongated channel. The elongated member is adapted to engage an edge of the printed circuit board along the channel. The member has an engagement portion for receiving an applied force, a driver portion for engaging an electrical connecting mechanism, and a translator portion for translating the force from the engagement portion to the driver portion.

A support bracket, which can be used in a method of reinforcing a printed circuit board, secures the printed circuit board, such as a backplane having a plurality of electrical connectors that engage corresponding electrical connectors of daughter boards. The support bracket includes a cross member attachable to the printed circuit board in a direction substantially transverse to a direction of motion of the daughter boards. The support bracket also includes first and second end support members attached transversely to the cross member at corresponding ends of the cross member. The end support members are fixable to a support surface and are adapted to secure the support bracket in the direction of motion of the daughter boards.
