The two riser cards are disposed on the mounting cage and are located in the two accommodation spaces, respectively. The two graphics cards are located in the two accommodation spaces and are detachably inserted into the two riser cards, respectively.

A blank panel of the present disclosure includes a partial panel and a partial panel, in which the partial panel includes an attachment portion attached to a rack and a link portion linked to the partial panel, and the partial panel includes an attachment portion attached to the rack and a link portion linked to the partial panel.

A rail vehicle control relay board includes a main frame, a mother board and a daughter board assembly which are arranged in the main frame, the main frame includes a board face mounting frame and a daughter board mounting frame which protrudes from the board face mounting frame, the mother board is arranged in the board face mounting frame, and multiple daughter board assemblies perpendicular to the mother board are arranged side by side in the daughter board mounting frame, the daughter board assemblies are electrically connected to the mother board, and multiple first connectors configured to perform output outwards are arranged on the mother board. The rail vehicle control relay board has a high strength, and may reduce the daughter board loosening faults, extend a wiring space and increase the number of relays arranged.

A chassis to receive a line replaceable module including a molded body formed from a composite material, a card guide integrally formed in the molded body to receive the line replaceable module, the card guide including a card guide wall integrally formed in the molded body and extending outwardly from the molded body, and a plurality of tolerance features disposed within the card guide to retain the line replaceable module.

A rack within a datacenter or other environment can include a plurality of appliances arranged in the rack such that ports of the appliances are aligned vertically or in another direction. A cartridge can include an elongate rigid body along which connectors are arranged. The connectors may be engageable with the aligned ports of the appliances in response to translation of the cartridge toward the rack. The cartridge can include an electronics board within the elongate rigid body, and the electronics board can provide paths among subsets of the connectors, for example, such that subsets of the appliances are accordingly connected for transmission of data or other signals.

A flow-through card rail module is provided in a circuit module chassis assembly for an embedded computing system. A set of elongated guide rails are formed on a base plate and define a card channel for receiving a circuit card. Each guide rail has a cooling passage extending from a fluid inlet to a fluid outlet. A corrugated structure is formed on an opposite side of the base plate and includes a set of elongated cells. Each elongated cell has a cooling passage formed therein extending from the fluid inlet to the fluid outlet. Internal walls subdivide the cooling passages formed in the guide rails and the elongated cells to form a honeycomb structure. The flow-through card rail module including the base plate, the guide rails and the corrugated structure may be formed as a monolithic component.

A carrier assembly configured to facilitate manufacture of a printed circuit board assembly includes a bottom frame defining a generally rectangular configuration and having a length and a width. The bottom frame is adjustable to vary at least one of the length or the width thereof. The assembly further includes a core releasably positionable on the bottom frame and configured to support a circuit board thereon. A carrier assembly system includes the bottom frame and a plurality of cores. Methods of manufacturing printed circuit board assemblies utilizing carrier assemblies are also provided.

An information handling system includes a connection tab physically coupled to a top cover of the information handling system, and a sliding bracket configured to engage with a riser cage of the information handling system and the connection tab of the top cover. A mezzanine card holder has an alignment sleeve through which a standoff of a system board of the information handling system may be inserted, such that the standoff may engage with the sliding bracket.

The invention relates to an assembly for securing at least one expansion card (comprising a half-open chassis for receiving a first circuit board of a server module having at least one first plug connector, a carrier component for receiving at least one expansion card and at least one second circuit board secured to the carrier component. The carrier component comprises at least one securing point for rotatably and releasably receiving the carrier component on the half-open chassis and at least one first bearing surface for supporting the carrier component on a second bearing surface of the half-open chassis, arranged in the region of opposite ends of the carrier component. Here, a first mating plug connector of the second circuit board is arranged such that the second circuit board is electrically connected to the first circuit board by receiving and pivoting the carrier component around the securing point.
