An electronic device that is able to operate by receiving a power supply from a host device through a Universal Serial Bus (USB). The electronic device acts as a first sink device and is connected to a second sink device that is able to operate by receiving a power supply from the host device through the USB and the connection to the first sink device. Each of the first sink device and the second sink device is provided with a CC terminal that obtains power supplying capability information from the host device, a pull-up or pull-down resistor connected to the CC terminal, and a GND terminal that grounds a circuit of the CC terminal and the pull-up or pull-down resistor. The electronic device changes a state of grounding of the pull-up or pull-down resistor to the GND terminal, in one of the first sink device and the second sink device.

One embodiment provides a system and method for reshaping the power budget of a cabinet to facilitate an improved deployment density of servers. A battery cabinet comprises: a plurality of sealed batteries; a power outlet; and a power management module coupled to the sealed batteries and the power outlet. The power management module comprises: a power monitoring module configured to monitor a first amount of power consumed by one or more computing devices via a main power supply; a detection module configured to detect that the first amount of power consumption exceeds a predetermined power consumption threshold; and a power provision module configured to provide, via the sealed batteries, power to the power outlet until the first amount of power consumption no longer exceeds the predetermined power consumption threshold.

A desktop computing system having at least a central core surrounded by housing having a shape that defines a volume in which the central core resides is described. The housing includes a first opening and a second opening axially displaced from the first opening. The first opening having a size and shape in accordance with an amount of airflow used as a heat transfer medium for cooling internal components, the second opening defined by a lip that engages a portion of the airflow in such a way that at least some of the heat transferred to the air flow from the internal components is passed to the housing.

A device heater module can be installed within a device such as a server, and can prevent the device from powering on while the temperature of the device is being restored to an operating temperature. The device heater module can prevent the device from powering on by operating a switch to disconnect the device from an external power supply. The device heater module can thereafter actively or passively modify the temperature of the device. After the temperature of the device is restored to within the operating temperature, the device heater module can operate the switch to reconnect the device to the external power supply, thereby allowing the device to initiate a boot process.

A device having fool-proofing structure is configured to be inserted into a cabinet along a first direction and includes a case and an elastic sheet module. The elastic sheet module is disposed on a side of the case and includes a first end disposed on the case, a second end opposite to the first end, a first protrusion portion and a second protrusion portion. The first protrusion portion is adjacent to the second end, protrudes from the case and is configured to abut against the cabinet. The second protrusion portion is farther from the second end than the first protrusion portion, protrudes from the case, and is configured to make the second end and the first protrusion portion move toward the interior of the case as being pressed by a force.

The present invention provides an electronic device including a replaceable module and a sliding fastener. The replaceable module is provided with a first sliding track on one side thereof. The sliding fastener includes a body, which is provided with a second sliding track connected to the first sliding track. The body is provided with a latch, a handle is extended from the body, and a groove is traversely disposed at a joint between the body and the handle. The sliding fastener is elastically bendable along the groove, such that the handle is enabled to turn along the groove relative to the body so as to be adhered to or erected on a surface of the replaceable module.

Systems for unlocking and locking a riser cage to a computing device are described herein. Such systems may include: a riser cage in a computing device; an axis member coupled to a first side of the riser cage and adapted to rotate about an axis; a handle coupled to the axis member and adapted to rotate the axis member about the axis; a cam, coupled to the axis member, and adapted to rotate about the axis when the axis member rotates; and a lever coupled to a second side of the riser cage and adapted to rotate about a pivot point when the cam rotates, wherein the lever engages with a stabilizing feature when the handle is in a first handle position.

A controller and a rectangular parallelepiped power supply apparatus are coupled to a rear surface of a midplane, to which a plurality of storage media drives are coupled in a front surface of the midplane. A plurality of interface connectors arranged in a left-right direction are provided at a front end of a controller substrate. The rear surface of the midplane includes a plurality of connectors for controller, which are a plurality of connectors arranged in the left-right direction to which interface connectors of the controller are respectively coupled, and a connector for power supply, which are connectors to which a power supply apparatus set horizontally is coupled. A part of a row of the connectors for controller is present below the power supply apparatus coupled sideways to the connector for power supply.

A source module includes a server fluid distribution unit and a busbar unit, as well as connectors. In an embodiment, a server fluid distribution unit to be coupled to a rack fluid distribution unit and the one or more server blades for deploying one or more servers. In an embodiment, a busbar unit to be coupled with an alternating current (AC) power distribution unit and the one or more server blades. In an embodiment, the source module is to be coupled to the rack fluid distribution unit to distribute cooling fluid received from a cooling fluid source to the one or more server blades of corresponding server chassis and to extract heat from the one or more servers.

A power connector includes a first printed circuit board (PCB) to connect to a plurality of power cables and receive power from the plurality of power cables. The power connector also includes a plug, which is electrically connected to the first PCB, to connect to a graphics card and provide the power to the graphics card. The power connector may further include a second PCB electrically connected between the first PCB and the plug, a casing to house the first PCB and/or the second PCB, and/or light-emitting diodes (LEDs) to be illuminated during operation of the graphics card.
