Filed:

Jun 30, 1998

Appl. No.:

09/107056

Inventors:

Erik Nelson - Upton MA
Jeffrey Teachout - Upton MA

Assignee:

EMC Corporation - Hopkinton MA

International Classification:

A47B 300

US Classification:

108134, 3123215

Abstract:

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.

Appl. No.:

10/402883

Inventors:

Erik C. Nelson - Upton MA, US
Fernando Luis Castro - Natick MA, US

Assignee:

EMC Corporation - Hopkinton MA

International Classification:

A47B097/00

US Classification:

312352

Abstract:

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.

Abstract:

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.

Assignee:

EMC Corporation - Hopkinton MA

International Classification:

E05C 19/00

US Classification:

292302, 312222

Abstract:

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.
