Embodiments promote the maintenance of a designed flow of cooling air through a chassis during the servicing of one or more electronic components contained by the chassis. A top opening created by the removal of server chassis from a rack may be significantly reduced by internal lids that provide access to groups of components. Gaps created by the partial removal of groups of components may be significantly reduced by air dams attached to the components that inhibit the flow of air between the components. And the opening created by the removal of a circuit board may be significantly reduced by a flap configured to cover the opening upon removal of the circuit board. The various embodiments may be used individually or in combination to reduce openings in the chassis that may allow air to flow in paths that negatively affect the designed air flow.

A system and method of mounting and electrically contacting a first printed circuit board perpendicularly onto a second printed circuit board within a housing includes inserting the first printed circuit board into an upper part of the housing using a stop surface arranged on an inner side surface of the upper part of the housing and arranged to support the electrical contacting and assembly, locking the first printed circuit board in the upper part of the housing using a locking system, and mounting the upper part of the housing with the locked printed circuit board on a lower part of the housing in which the second printed circuit board is mounted.

Examples may include racks for a data center and sleds for the racks, the sleds arranged to house physical resources for the data center. The sleds and racks can be arranged to be autonomously manipulated, such as, by a robot. The sleds and racks can include features to facilitate automated installation, removal, maintenance, and manipulation by a robot.

Embodiments are generally directed apparatuses, methods, techniques and so forth to select two or more processing units of the plurality of processing units to process a workload, and configure a circuit switch to link the two or more processing units to process the workload, the two or more processing units each linked to each other via paths of communication and the circuit switch.

A scalable system for high-power computer, comprising a plurality of motherboard chassis, inserted in a computer rack mounting kit, each motherboard chassis, being configured to receive at least one motherboard module, said plurality of inner chassis forming a stack of inner chassis, the stack being configured to receive an outer floating bracket chassis, said outer chassis being inserted by a second longitudinal end of each inner chassis forming the stack of inner chassis, each said outer floating bracket chassis being configured to accommodate at least one double floating bracket being configured to house a cable box capable of connecting the connectors of a plurality of motherboard modules, arranged in said inner chassis of the stack, to each other, the system being characterized in that the double floating bracket comprises at least several floating attachment means.

A shell structure including a shell, a baffle plate, and a positioning member is provided. The shell has a first surface, a second surface opposite to the first surface, and an expansion opening and a first mounting hole penetrating the first and second surfaces. The baffle plate is detachably mounted to the shell and includes a body portion located in the expansion opening and a side wing portion located outside the expansion opening and in contact with the second surface. The side wing portion includes a second mounting hole overlapped with the first mounting hole. The positioning member passes through the first and second mounting holes, and includes a first positioning portion in contact with the first surface and a second positioning portion passing through the second mounting hole. A maximum outer diameter of the second positioning portion is greater than an inner diameter of the second mounting hole.

An enclosure assembly for housing printed circuit boards and related electrical components having a secured faceplate that may be removed by use of a hand tool.

The disclosure relates to a cage and an electrical device having the same, where the cage is configured to accommodate at least one expansion card and includes a cage body, a rail, and at least one holder. The cage body is configured to accommodate the at least one expansion card. The rail is fixed on the cage body. The rail has a groove configured for an insertion of the at least one expansion card. The at least one holder is movably disposed on the cage body. Part of the at least one holder is removably located in the groove. The at least one holder is configured to block the at least one expansion card in the groove.

An expansion bay for a computer device for easy insertion and extension of an expansion component is disclosed. The expansion bay has two facing side walls, a bottom panel joining the facing side walls, and a closed end. A front cross member joins the side walls to define a front open end. A pair of springs are located the closed end that force the expansion component away from the closed end. A pair of rotating levers are mounted on the front cross member near each of the side walls. Each of the rotating levers has a pin that engages a groove on the expansion component that is inserted through the open front end. The levers are rotated via the pins engaging the grooves when the expansion component is moved into and out of open front end.
