A computer system includes a computer casing having a casing wall having an opening to pass through a connection means; a circuit board having the connection means; and a centering means arranged in the casing, wherein the centering means is formed to cooperate with the circuit board such that the circuit board is centered with respect to the casing wall in a direction of the casing wall in a placing movement so that the connection means takes a predetermined position flush with respect to the opening in the casing wall and can plunge into the opening.

A securing apparatus configured to mount a data storage device in an enclosure includes a shielding assembly configured to be secured to a panel of the enclosure and a sliding pole. The shielding assembly includes a frame and a rotating plate rotatably mounted to the frame. The sliding pole is slidably mounted to the frame and defines a plurality of latching slots. The frame defines an aperture for the data storage device to pass through; the rotating plate comprises a plurality of hooks. The sliding pole is slidable relative to the frame to engage the hooks in the latching slots. The rotating plate is secured to the frame and shields the aperture, preventing the data storage device from being taken out of the enclosure.

Implementations of the subject matter described herein provide an input/output (I/O) card for storage device and a storage device. The I/O card and the disk drive for the storage device have the same form factor and comply with the same protocol, to enable the I/O card and the disk drive can be arranged at the same end of the storage device.

An internal support bracket for a power switch includes a bottom support and a top cover. The top cover is secured to the bottom support. The combined bottom support and top cover define an aperture for securing the power switch. The bottom support includes a bottom surface with a ridge protruding therefrom. A method of securing a power switch to the interior of a computer chassis includes connecting a base support including a channel to an interior wall of the computer chassis. A power switch is positioned between a top cover and a separate bottom support. The separate bottom support includes a ridge protruding from a bottom surface. The top cover is secured to the separate bottom support. The ridge of the separate bottom support is slid into the channel such that the internal support bracket including the power switch is secured in a locked position.

An electronic device including a chassis, a motherboard, an expansion card and a support. The motherboard is disposed in the chassis. The expansion card includes a circuit board assembly and a fixing plate. The circuit board assembly is fixed to a side of the fixing plate. The circuit board assembly is electrically connected to the motherboard and is fixed to the chassis via the fixing plate. A side of the support supports a side of the circuit board assembly that is located farthest from the fixing plate. A side of the support that is located farthest from the circuit board assembly is fixed to the motherboard and the chassis.

A control system, a switch, and a method for controlling an execution device. The control system comprises a processor, a control module, and address resolution modules. The processor is connected to the control module by means of a peripheral component interconnection high-speed PCIe bus, the control module is connected to one or more address resolution modules by means of address buses, and each address resolution module is configured to be connected to one execution device, wherein address information of a port to be controlled on each execution device is preconfigured on the processor, and the address information is used for enabling the processor to address to a corresponding address resolution module by means of the control module.

An external function extension device includes a casing, a transition circuit board, a liquid cooling system, at least one connecting member and a power supply unit. The transition circuit board, the liquid cooling system and the power supply unit are disposed in the casing. The transition circuit board has a transition slot. The connecting member is connected to the liquid cooling system. The connecting member is used for connecting an external device, such that the liquid cooling system performs liquid cooling function for dissipating heat of the external device. The power supply unit is electrically connected to the transition circuit board and the liquid cooling system. The power supply unit includes an electric connector. The electric connector is used for connecting the external device, such that the power supply unit supplies power to the external device.

An insertion tool for assisting in the insertion of an OCP 3.0 type expansion card in an expansion card slot of a computer system is disclosed. The expansion card may be a pull tab type form factor that does not have a mechanism such as an ejector latch to assist in applying force to insert the card. The expansion card has a front panel opposite a distal edge connector. The tool has a handle and a head coupled to the handle. The head has two contact areas that contact different areas of the front panel of the expansion card. For example, one of the contact areas may be an extended side arm and the other area may be a lateral rib extending from the head.

In some embodiments, an apparatus can include a host board that has multiple connectors. Each connector from the multiple connectors removably connects to a unique compute device from multiple compute devices. The apparatus can further include a memory that stores a first firmware. The apparatus can further include a controller that is operatively coupled to the multiple connectors and the memory. The controller provides access to the first firmware by a compute device from the multiple compute devices when the compute device removably connects to the host board via a connector from the multiple connectors and when a circuit of the compute device disables access to the memory of the compute device to cause the compute device to continue a power-on cycle using the first firmware.

In computing scenarios involving multiple computational units, an enclosure (e.g., a rack or server cabinet) may store the units and provide resources such as shared power and network connectivity. Additionally, the components of the units may communicate through a Serial Attached SCSI (SAS) bus, but many such enclosures provide little or no integration with the SAS buses, thus entailing extensive SCSI cabling. Presented herein are architectures for enclosures presenting a set of slots for trays storing respective computing blades, where such trays include SAS connectors that connect directly (i.e., without cabling) with connectors on a midplane that interconnects the blades into a SAS bus featuring at least one integrated SAS expander. Additional architectural variations involve providing SAS expander on one or both of the midplane and the blades; grouping blades into subsets having distinct SAS buses; and interconnecting the SAS buses and expanders of multiple midplanes in the enclosure.
