Abstract: Switches and groups of IO ports, conventionally integrated on a single shared PCB, may be divided into separate switch modules and IO modules that can be connected by high-speed low-loss management cables in a variety of configurations. Thereafter, the separate modules may be replaced independently of each other. Some of the management connections may be parallel, similar to production-data connections. Alternatively, a series of IO modules (e.g., a chain or a ring) may be managed by a single switch module using a management method. The management method may include collecting and updating configuration and status information specific to each of the IO modules and, by extension, each of their IO ports. This enables the switch module to recognize, and thereafter ignore, unconnected ports, removing the performance penalty that sometimes arises when fewer than all available ports are connected. It also allows the switch module to rapidly adjust to addition, subtraction, and replacement of connected IO modules.

Abstract: Examples described herein include latch mechanisms for covers. In some examples, an electronic device has an enclosure, a cover, and a latch mechanism. The enclosure may include an opening. The latch mechanism may include a rotatable arm, a spring to bias the rotatable arm to secure the cover to the enclosure, and a cam moveable between a rest position and an engaged position. In the engaged position, the cam moves the rotatable arm to release the cover.

Abstract: A device assembly as disclosed herein includes a heat pipe coupled to a heat transfer device, and a thermal interface. The assembly further includes a cold plate rotatably coupled with the heat pipe through a hinge. The thermal interface is coupled with the cold plate through a plane to rotate about the heat pipe together with the cold plate, and the thermal interface includes a material having a thickness and a resiliency configured to make thermal contact with a circuit in a circuit card when the cold plate is rotated over the circuit card. A chassis and a method to build the chassis including the above assembly are also disclosed.

Abstract: Blind mate connection techniques and associated connectors are disclosed. Blind mate connectors provide connections where visual inspection at time of connection may not be available. Stacking tolerance increases when connectors have a different set of datums (e.g., a different relative orientation) relative to adjacent connectors. Different datums permit twinning two printed circuit boards (“PCBs”) prior to insertion into a slot of a chassis. Each connector may be attached to a respective PCB utilizing a spring and offset feature to provide a standoff on a respective PCB. Control of standoff and rotational movement (e.g., via brackets) allows each individual connector to have a “float” for improved insertion tolerance. Connector pairs may connect through an opening in a midplane while simultaneously connecting to the midplane. Switch trays and node trays may be inserted through opposing sides of a chassis and be connected through the midplane of that chassis.

Abstract: Embodiments are directed to an assembly including a bay structure including a bay structure that defines a bay for receiving a pluggable module and including sides and a front plate rotatably connected to the sides, a connecting bracket coupled with the bay structure, and a heat transfer device coupled with the bay structure. The bay structure, the heat transfer device, and the connecting bracket are configured such that rotating the front plate from a first position to a second position displaces the connecting bracket in a first direction which causes the connecting bracket to displace the heat transfer device in a second direction transverse to the first direction.

Abstract: In example implementations, a memory cooler is provided. The memory cooler includes a body. The body includes two pieces that are moveable relative to one another. Each piece of the body includes an inlet manifold, an outlet manifold, and a plurality of cold plates extending between the inlet manifold and the outlet manifold. The inlet manifold is to receive liquid coolant from a liquid coolant supply line. The outlet manifold is to return the liquid coolant to the liquid coolant supply line. The liquid coolant flows from the inlet manifold to the outlet manifold through interior channels of the cold plates. The plurality of cold plates of a first piece of the body are interleaved with the plurality of cold plates of a second piece of the body such that slots to receive memory modules are defined between adjacent pairs of cold plates.

Abstract: Example implementations relate to a handle made of a single metal sheet. In one example, the handle includes a plurality of chamfered edges where each edge includes a first side and a second side. The handle includes a rolled-over top cover and a rolled bottom edge disposed between each of the plurality of chamfered edges. The handle also includes a latching extension disposed adjacent to each of the plurality of chamfered edges. The latching extension of the handle includes a pivot hole, an engaging indentation, and a hook located at an endpoint of the latching extension.
