Patent number: 7663889Abstract: An assembly is disclosed which enables a printed circuit board (PCB) to be added to or removed from a computer system without deactivating other parts of the system. The assembly, which holds the PCB, translates lateral motion into vertical motion to enable lateral motion to be applied to derive the vertical motion needed to plug and unplug a PCB into and out of an expansion slot. This motion translation makes it possible to insert or remove a PCB via a rear, front, or side access portal of a housing rather than through the top of the housing. Thus, the assembly eliminates the need to remove the housing from a rack, or to remove a top from the housing, which in turn eliminates the need to shut down any other parts of the system. Thus, the assembly enables a PCB to be “hot swapped” into and out of a computer system.Type: GrantFiled: October 23, 2006Date of Patent: February 16, 2010Assignee: Sun Microsystems, Inc.Inventors: Robert J. Lajara, Kenneth Kitlas, Bakul V. Herekar

Patent number: 6921247Abstract: A fan tray assembly for an electronics enclosure includes two opposing, spaced apart shells made of a sheet material. The opposing shells are attached to each other by attachment features formed in the sheet material of each shell. Advantageously, the attachment features reduce or eliminate the need for separate fasteners, spring steels, or adhesives to attach the shells. Each shell has openings and grills. Each shell also has retention features formed in the sheet material around a periphery of their respective grills. A ventilation fan unit (e.g., two fans) is retained between the two shells by the retention features. An electrical connector is connected to the ventilation fan and retained by at least one of the shells. The shells may also include features for retaining the electrical connector without using fasteners or adhesives. Such features may allow the connector to float in a plane perpendicular to its principal axis of alignment.Type: GrantFiled: April 14, 2003Date of Patent: July 26, 2005Assignee: Sun Microsystems, Inc.Inventors: Thomas E.

Patent number: 6542362Abstract: A computer system housing with a curved bezel that forms one or more sideways gap between a side of the computer housing chassis and the bezel attached to that side. Typically, the curved bezel is attached to the front of the chassis with each sideways gap extending perpendicularly from the front of the chassis to a predetermined width and stretching to predetermined length along the front of the chassis. The sideways gaps facilitate increased air inlet from the sides and allow efficient cooling of various system components that are mounted on the chassis and housed within the housing. One or more cooling fans may be mounted at different locations within the housing to optimize air circulation and, hence, cooling within the housing. The chassis may be partitioned into two separate sub-chassis for proper positioning of the cooling fans as well as to accommodate changes in computer system configurations with minimized retooling of the chassis.Type: GrantFiled: December 7, 2001Date of Patent: April 1, 2003Assignee: Sun Microsystems, Inc.Inventors: Robert J.

Patent number: 6362968Abstract: A stiffener for a printed circuit board where the stiffener is placed between the printed circuit board and a wall of the metal chassis in a computer system housing. The loaded printed circuit board may first be mounted on the stiffener, which, in turn, may then be mounted on the appropriate wall of the chassis along with the circuit board. Alternately, the stiffener may first be mounted on the appropriate chassis wall, and the circuit board may then be mounted on the stiffener. Additional circuit components may then be added onto the circuit board. The lies between the circuit board and the wall of the chassis on which the circuit board is being mounted. The back plane support provided by the stiffener may reduce damage to the conducting paths of the printed circuit board due to pressures exerted during component mounting, manufacture, transportation, etc. Additionally, a circuit board carrying densely populated electronic components may be easily mounted on or removed from the chassis without damage.Type: GrantFiled: June 28, 1999Date of Patent: March 26, 2002Assignee: Sun Microsystems, Inc.Inventors: Robert J.

Patent number: 5287244Abstract: The present invention is a computer housing with a low noise cooling system. The computer housing is comprised of two principal members, a cover and a base. Both a left surface and a right surface of the cover are perforated with vents to allowing the passage of air through the housing. The base additionally incorporates two air intake holes with a power source for the computer disposed over these air intake holes. The passage of air through the housing is facilitated through the use of three fans. These three fans are attached directly to the power source, and each of these fans operates at a different fan speed. The fan speeds are additionally adjusted in response to the outside ambient temperature. In operation, air enters the computer housing of the present invention through the vent array on the left surface of the cover, and the air intake holes in the base.Type: GrantFiled: May 19, 1992Date of Patent: February 15, 1994Assignee: Sun Microsystems, Inc.Inventors: Vincent P.

Patent number: 5260854Abstract: A modular circuit board placement system is disclosed that provides for flexible placement of daughterboards, for minimal bus signal path lengths between motherboard and daughterboards, and for ease of installation and removal of daughterboards. The placement system employs dual height bus connectors, a stepped back panel, easy to engage and disengage dual height card retainers, filler panels that also function as module mounts, and multipurpose circuit card handles that facilitate removal of daughterboards. Daughterboards have a two-tier staggered arrangement above the motherboard. Each daughterboard has a signal transfer end that electrically connects to the motherboard through one of the dual height bus connectors, and a back panel connector end that couples to the back panel with an accessory connector or with a filler panel that functions as an electromagnetic interference shield.Type: GrantFiled: May 14, 1992Date of Patent: November 9, 1993Assignee: Sun Microsystems, Inc.Inventors: Vince Hileman, Steven J.
