Methods, systems, and apparatuses provide power from multiple input power sources to adjacent outputs efficiently and reliably. Aspects of the disclosure provide a power distribution unit (PDU) that includes a number of power outputs including first and second adjacent power outputs. The PDU includes a printed circuit board having a first conducting layer electrically interconnected to a first power input connection and the first power output, a second conducting layer that is at least partially above the first conducting layer and in facing relationship thereto. The second conducting layer is electrically insulated from the first conducting layer and electrically interconnected with a second power input connection and the second power output, the first and second power outputs thereby connected to different power inputs.

A hybrid management cable includes a cable connector having a first cable sub-connector and a second cable sub-connector, The cable connector connects to a hybrid management switch connector on a hybrid management switch and, in response, engages the first cable sub-connector with a first hybrid management switch sub-connector on the hybrid management switch connector, and engages the second cable sub-connector with a second hybrid management switch sub-connector on the hybrid management switch connector. A cable conduit extends from the cable connector. A first management data transmission medium is connected to the first cable sub-connector, located in the cable conduit, and extends along the length of the cable conduit. A second management data transmission medium is connected to the second cable sub-connector, located in the cable conduit and isolated from the first management data transmission medium, and extends along the length of the cable conduit.

A stackable connector interface with magnetic retention for electronic devices and accessories can allow power and data to be transferred between one or more stacked connectors. Each interconnected stackable connector includes one or more magnetic elements, which magnetic elements have poles arranged to facilitate mating with other stackable connectors. The magnetic elements provide a magnetic retention force that holds mated connectors in contact with each other. In some embodiments, the connectors include connection detection circuitry for determining whether the connectors are mated with other connectors, thereby allowing the connectors to prevent live contacts from being exposed at an unmated surface of the connectors. In some embodiments, routing circuitry is included to determine how signals should be transferred between the interconnected stackable connectors and/or corresponding devices.

Various techniques for flexible power supply in computing facilities are described herein. In one embodiment, a power distribution unit includes a first subsystem for receiving power from a power source and a second subsystem electrically coupled to one or more of the processing units in the component enclosure. The first subsystem includes a number of power supplies coupled to the power source, and the number of power supplies corresponds to a power requirement of the processing units.

Housing for a module outlet includes first housing with a first opening configured to receive a body of a first outlet core so that a lip area of the first outlet core prevents the first outlet core from travelling through the first opening. A tab is configured to hold the body of the first outlet core secure within the first opening. A dovetail tongue is configured for sliding into a dovetail groove of a second module housing so as to secure the first module housing to the second module housing.

A ganged connector assembly includes: first, second, third and fourth coaxial cables; first, second, third and fourth coaxial connectors, each of the coaxial connectors connected with a corresponding one of the coaxial cables; a shell surrounding the coaxial connectors, the shell configured to electrically isolate each of the coaxial connectors from the other coaxial connectors, wherein the coaxial connectors are arranged in a generally square pattern; and a strain relief boot comprising: first and second cover pieces that are assembled to create a cover around portions of the coaxial cables and the coaxial connectors; and first and second braces that reside within the cover, the first brace being positioned between first and second of the coaxial connectors, and the second brace being positioned between third and fourth of the coaxial connectors.

An electrical receptacle is selectively coupled to a power plug, and the power plug includes a plurality of prongs insertable into the electrical receptacle. The electrical receptacle includes a contact configured to be engageable with one of the plurality of prongs, a power relay in electrical communication with the power source and the contact, and a switch electrically coupled to the power relay. The switch is moveable between a first position and a second position. The switch is biased toward the first position. The power relay is configured to disable electrical communication between the power source and the contact when the switch is positioned in the first position. The power relay is also configured to enable electrical communication between the power source and the contact in response to the one of the plurality of prongs slidably engaging the switch to move the switch into the second position.

Systems, methods, and devices for electrically coupling an integrated circuit to a set of coaxial lines via a printed circuit board assembly are described. A device sample holder includes a printed circuit board that is operable to edge-couple to an integrated circuit. A surface of the printed circuit board that carries a set of coaxial connectors is orthogonal to another surface of the printed circuit board that exposes a set of conductive traces. The set of conductive traces are operable to electrically couple to a set of conductive paths of an integrated circuit to provide a communicative path between the integrated circuit and components of an input/output system in a refrigerated environment.

An electrical power or data system includes an electrical power or data supply cord and an intermediate power or data cord, a first electrical power or data outlet receptacle disposed between the supply cord and the intermediate cord, and a second electrical power or data outlet receptacle at a distal end of the intermediate cord. The first electrical power or data outlet is positionable below a work surface, while the second electrical power or data outlet is mountable to the work surface. At least one of the electrical cords may include a self-retracting cord section.
