Systems and methods for improved circuit board removal and/or reinstallation are provided. A circuit board removal system can include a frame including a channel arranged in a plate of the frame. A disengagement slider can include a mounting surface and a first portion including a first cam surface, where the disengagement slider is arranged within the frame. A separator can include a second cam surface and can be arranged in the channel of the plate. The first cam surface and the second cam surface can be nested with each other when the disengagement slider is in an inserted position. The disengagement slider can be configured to slide the separator in the longitudinal direction when the disengagement slider is removed from the frame due to the interaction of the first cam surface with the second cam surface.

A stiffener for an integrated circuit (IC) package assembly including an IC die electrically interconnected to a substrate. The stiffener is to be mechanically attached to the substrate adjacent to at least one edge of the IC die and have a coefficient of linear thermal expansion (CTE) exceeding that of the substrate. The stiffener may be an “anti-invar” metallic alloy. Anti-invar alloys display “anti-invar” behavior where thermal expansion of the material is significantly enhanced relative to other compositions of the particular alloy system. A package stiffener may be a high-Mn steel, for example, such as ASTM International A128. In other examples, a package stiffener is a MnCuNi, FeNiMn, or FeNiCr alloy having an average CTE over a range of 25-100° C. of at least 18 ppm, and a room temperature modulus of elasticity of at least 120 GPa.

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.

An auxiliary sliding connection assembly, which includes a pair of fixing rails, at least one automatic locking mechanism and a manual unlocking mechanism arranged adjacent to each automatic locking mechanism; the pair of fixing rails have the automatic locking mechanism enabling a locking hole to be automatically locked and arranged corresponding to the locking hole preformed on a second board member, so that a removable unit having the second board member can generate an automatic locking function applied a main frame having a first board member during sliding on the pair of fixing rails, thus a connector of the first board member and a connecting plug of the second board member can be prevented from separating; the manual unlocking mechanism is capable of forming a locked status to each automatic locking mechanism, so that the removable unit can be easily held by a user for being removed.

An electronic module assembly includes a circuit card assembly (CCA) with heat generating electronic components. A connector is electrically connected to the heat generating electronic components, wherein the connector is positioned at a connection end of the CCA. A heatsink is mounted to the CCA, connected in thermal communication with the electronic components. An undulating channel feature is defined along a lateral edge of the heatsink relative to the connector. One or more channels of the undulating channel feature are aligned with an insertion axis defined by the connector.

Embodiments are generally directed apparatuses, methods, techniques and so forth to receive a sled manifest comprising identifiers for physical resources of a sled, receive results of an authentication and validation operations performed to authenticate and validate the physical resources of the sled, determine whether the results of the authentication and validation operations indicate the physical resources are authenticate or not authenticate. Further and in response to the determination that the results indicate the physical resources are authenticated, permit the physical resources to process a workload, and in response to the determination that the results indicate the physical resources are not authenticated, prevent the physical resources from processing the workload.

A circuit card assembly for a vehicle chassis is provided. The circuit card assembly may include a circuit card unit, a wedge-lock retainer unit, and a support bracket. The circuit card unit has a printed circuit board (PCB) defining a first fastener aperture. The wedge-lock retainer unit may define a second fastener aperture. The support bracket includes first and second elements. The first element may define a third fastener aperture and the second element may define a fourth fastener aperture. The PCB, the wedge-lock retainer unit, and the support bracket may be arranged with one another such that the first fastener aperture, the second fastener aperture, and the third fastener aperture are aligned with one another and such that the fourth aperture is oriented in alignment with a chassis aperture of a chassis.

A modular high density communications chassis, comprising a chassis and slidable carrier module is provided. The chassis comprises a second track having a first and second stage access fixing recess and a sectional sliding mechanism having a moveable squeeze-release latching rail mechanism. The slidable carrier module comprises a push-pull tab and a snap-fit mechanism, and is slidably mounted to the second track and squeeze-release latching rail mechanism. The slidable carrier module is slidably mounted to the chassis vertically. The snap-fit mechanism is configured to secure and release the slidable carrier module in and from a first stage position when corresponding to the first stage access fixing recess, and in and from a second stage position when corresponding to the second stage access fixing recess, via pulling and pushing of the at least a push-pull tab, respectively, providing staged access to the slidable carrier module and staged management of the connector cables extending to and therefrom.

An auxiliary sliding connection assembly, which includes a pair of fixing rails, at least one automatic locking mechanism and a manual unlocking mechanism arranged adjacent to each automatic locking mechanism; the pair of fixing rails have the automatic locking mechanism enabling a locking hole to be automatically locked and arranged corresponding to the locking hole preformed on a second board member, so that a removable unit having the second board member can generate an automatic locking function applied a main frame having a first board member during sliding on the pair of fixing rails, thus a connector of the first board member and a connecting plug of the second board member can be prevented from separating; the manual unlocking mechanism is capable of forming a locked status to each automatic locking mechanism, so that the removable unit can be easily held by a user for being removed.
