An expansion module for a computing unit of a High-Performance Computer cabinet, the expansion module comprising a casing configured to be removably guided horizontally in a main housing of a computing unit of a High-Performance Computer cabinet, a support card, mounted within the casing, comprising at least one module connector, said module connector being configured to be removably connected to the computing unit, a plurality of card slots connectors, each card slot connector being configured to be removably connected to an expansion card, at least a lever for locking/unlocking the casing to the main housing of the computing unit, said lever being operable manually without using any tools and a handle, pivotable according to a vertical axis, configured for locking/unlocking simultaneously the expansion cards when mounted in the card slot connectors.

Disclosed is a two rack unit chassis and low profile tool-less hard disk drive carrier (HDD). The two rack chassis including a plurality of HDD bays and a backplane including a plurality of connectors corresponding to the plurality of bays, each bay configured to receive a low profile tool-less carrier. The low profile tool-less carriers each comprising a first latch configured to release a sidewall of the low profile tool-less carrier and receive an HDD, a second latch configured to release a lever having at least one protraction at an inward end, and the lever configured to couple the at least one protrusion of the low profile tool-less carrier to the connector of the corresponding bay to which the low profile tool-less carrier is inserted.

Modular elements removable from enclosures and employing cams forming detent features with latches are disclosed. A modular element may include a chassis body supporting electronic components. The modular element is removable from or secured to an enclosure using a latch. The latch may engage the enclosure and may remain engaged with the enclosure by being secured by interfacing with a cam. By forming the cam with a predetermined shape, a detent feature may be established with the latch to secure the latch and maintain the modular element locked to the enclosure. The latch may be disengaged from the cam by applying a disengagement motion to the cam and allow the latch to move relative to the chassis body and disengage from the enclosure. In this manner, the modular element is efficiently secured and removed from the enclosure with minimum obstruction to airflow to the electronic components.

A card ejector comprising a pair of tapered lever arms coupled at a proximal end of the card ejector and coupled at a distal end of the card ejector, a cam block coupling the pair of tapered lever arms at the proximal end of the card ejector, the cam block operable to be rotatably coupled to a card and to engage a card cage, the cam block operable to urge the card into or out of the card cage when a rotational force is applied to the card ejector, and a latching mechanism coupling the pair of tapered lever arms at the distal end of the card ejector, the latching mechanism operable to automatically and releasably secure the distal end of the card ejector in a position near a face portion of the card by engaging an opening in the face portion.

There is provided an apparatus, a method and computer program product for managing one or more components of an electronic machine. A user connects one or more components to an electronic machine in parallel. The electronic machine determines whether the components are failed. A latch device, attached to each component, automatically locks one or more of the components to the electronic machine if the one or more of the components are not failed. The electromechanical latch automatically releases the one or more of the components from the electronic machine if the one or more of the components are failed.

Example implementations relate to a security system having an electronic lock including latch and security modules, to control access to electronic devices. The latch module includes a receiver, a handle, and a torque member rotatably coupled to the receiver and handle. The receiver includes a first recess, a second recess, and a lobe to releasably engage the electronic device within the first recess. The security module includes a tension spring, an actuator, and a lock member having a first pin and a second pin. The tension spring is coupled to the lock member to engage the first pin to second recess when the latch module is in a latched configuration, and hold the security module in a lock-in position. The actuator is releasably engaged to the second pin for rotating the lock member to disengage the first pin from second recess, and release the security module from the lock-in position.

A chassis mounting frame includes a frame body, a fixing plate, a coupling member, a rotating member, and a pivoting member. The fixing plate is mounted on a side of the frame body and includes a resisting structure. The rotating member is provided on the frame body and coupled to the coupling member and configured to drive the coupling member to move inside the frame body and drive the coupling member and the frame body to move together. The pivoting member is provided on a side of the frame body and coupled to the coupling member. The coupling member is configured to drive the pivoting member to rotate to resist against the resisting structure.

A handle locking structure includes a handle having a pivot portion pivotally connected to a sliding box, a buckle portion for hooking on a cabinet and a handle shaft, and a positioning structure including a base connected to the handle shaft, a positioning device mounted in the base and an elastic member placed on the positioning device. When the handle is hooked on the cabinet, a peripheral limiter of a head member of the positioning device is disengaged from a position-limiting notch of the base to reset the elastic member, so that the positioning device is automatically locked to the sliding box, avoiding vibration of the handle and improving the locking stability of the handle.

An electronic apparatus including a housing, an electronic component unit main body, an engagement lever, and an engaged member, in which the engagement lever includes a lever main body, an engagement groove, and a restricting member, the lever main body is displaceable between a first state in which the one end portion is inclined to protrude rearward with respect to the other end portion in an insertion direction of the electronic component unit main body with respect to the accommodating part and the engagement groove abuts against the engaged member from the rear in the insertion direction, and a second state in which the lever main body is vertical from the one end portion to the other end portion and the engagement groove engages with the engaged member, and the restricting member is able to restrict the lever main body to being in the second state.

A chassis for housing a computing device of an information handling system includes an expansion card receiver. The chassis also includes an electrical receiver decoupler that partially ejects an expansion card from the expansion card receiver when an electrical connector of the expansion card is coupled to an electrical receiver of the expansion card receiver that enables the expansion card to be operably connected to a second component of the computing device. Partially ejecting the expansion card does not require the user of the chassis to physically contact the expansion card directly.
