A variable holder module secures a variety of different expansion cards that may be installed within a computer or other information handling system. The holder module has a multi-sided component that is orientable according to which expansion card is to be secured within the computer. Each side of the component may thus correspond to a different one of the expansion cards. Once the expansion card is determined, a human or robotic picker need only orient component to the side that corresponds to the make/model of the expansion card. The holder module is thus adaptable to secure many different expansion cards that may be installed within the computer.

In some examples, a printed circuit board assembly can include a printed circuit board having four (4) central processor unit (CPU) sockets disposed thereon and sixty four (64) dual in-line memory modules (DIMMs) disposed thereon. The printed circuit board can have a top surface and a bottom surface with two (2) CPU sockets and thirty two (32) DIMMs disposed on the top surface and two (2) CPU sockets and thirty two (32) DIMMs disposed on the bottom surface.

A plug-in device may include a circuit board, a first connecting piece stacked on the circuit board and a card tray stacked on the first connecting piece. The card tray may include a first mounting face facing the first connecting piece and a second mounting face away from the first connecting piece. The first mounting face may be configured to place a first chip card electrically connected to the circuit board through the first connecting piece. The second mounting face may be configured to place a second chip card electrically connected to the circuit board. A projection of the first mounting face along a direction perpendicular to the first mounting face may overlap that of the second mounting face. A terminal may include the above mentioned plug-in device.

A mounting frame apparatus is provided for embedding cards within an electronics system and includes a multi-card swappable subsystem. The apparatus further includes a chassis for containing the multi-card swappable subsystem. One or more heatsinks are used for cooling cards disposed in the four-card swappable subsystem.

A common carrier for different device cards for installation in a server is disclosed. The common carrier has a base module that includes side walls and a bottom panel. The bottom panel has a plurality of registration features, each of the registration features corresponding to one of a plurality of different device cards. A top cover includes side walls that is assembled with the base module. A device card of the plurality of different device cards is positioned between the base module and the top cover by at least one of the registration features.

In one embodiment, an apparatus includes a module adapter comprising a first connector for connection to a modular electronic system and a second connector for connection to a module inserted into a chassis of the modular electronic system to couple the module with the modular electronic system. The module adapter is removably inserted into the chassis of the modular electronic system with an adapter tool operable to lock the module adapter in place in the chassis. A method for insertion of the module adapter is also disclosed herein.

An apparatus case includes a first casing member, a second casing member, a driving portion, a blocking portion, and a rotary shaft. The first casing member and the second casing member are detachably engaged with each other. The driving portion is disposed on the first casing member. The blocking portion and the rotary shaft are rotatably disposed on the second casing member and connected with each other. A server includes the apparatus case and a circuit board disposed on the first casing member of the apparatus case. When the second casing member moves from a first position to a second position relative to the first casing member, the driving portion drives the rotary shaft to rotate so that the rotary shaft drives the blocking portion to rotate above an expansion slot of the circuit board.

A plug-in device may include a circuit board, a first connecting piece stacked on the circuit board and a card tray stacked on the first connecting piece. The card tray may include a first mounting face facing the first connecting piece and a second mounting face away from the first connecting piece. The first mounting face may be configured to place a first chip card electrically connected to the circuit board through the first connecting piece. The second mounting face may be configured to place a second chip card electrically connected to the circuit board. A projection of the first mounting face along a direction perpendicular to the first mounting face may overlap that of the second mounting face. A terminal may include the above mentioned plug-in device.

The present disclosure provides a card tray, a card tray plug-in device, and a terminal. The card tray may include a first supporting portion and a second supporting portion connected with the first supporting portion. The first and the second supporting portions may both be configured for placing data cards, and configured on a same side of the card tray along a thickness direction of the card tray. The card tray may include an electrical connection portion, a data card supported on the first supporting portion and/or another data card supported on the second supporting portion may electrically connect with a card holder of a terminal through the electrical connection portion.
