Abstract: A power supply unit (PSU) exhaust duct includes a plurality of duct walls configured to, when attached to a server, form an enclosed space in communication with a PSU exhaust port of a PSU of the server and an interior space of the server that is outside of the PSU. The PSU exhaust port may be disposed at a rear wall of the server, and the PSU exhaust duct may be attached to a rear wall of the server. By connecting the PSU exhaust port to the interior space of the server, PSU fans of the PSU become in series with server fans of the server (e.g., main cooling fans of the server). Doing so may increase an amount of cool air flowing through the PSU compared to conventional means where the PSU fans and the server fans are in parallel.

Abstract: The self-centering floating fluid coupler includes a body having a first port and one or more second ports in communication with the first port. The fluid coupler also includes a housing assembly surrounding the body. The housing assembly includes a first opening exposing the first port of the body and a second opening exposing the one or more second ports of the body. The fluid coupler further includes one or more bias members disposed within the housing and configured to bias the body to a central position within the housing assembly. The body is able to move within the housing assembly to accommodate misalignments between the first port and a corresponding connection location (e.g., a mating fitting). Furthermore, the body is biased back to the central position when connections are removed. Accordingly, the fluid coupler allows for a broad range of misalignments.

Abstract: A latch is provided for holding stacked expansion boards above a mother board that includes an auto-lock feature that triggers when an expansion board is installed and is reset when the board is removed. The latch includes a trigger arm above which a first latch slider and a second latch slider are stacked. Movement of the trigger arm caused by placement of an expansion board releases the first latch slider to an extended position that holds the expansion board in place. Downward movement of a second expansion board against the second latch slider forces the second latch slider back until the second expansion board is received by a gap between the first and second latch sliders.

Abstract: A method and guide are provided that facilitate the installation and removal of cabling in hard-to-reach locations using a holder to maintain the relative locations of a cable and cable-side connectors and a handle that slides with respect to the holder. The handle may be used to move the cable and cable-side connectors into position with respect to board-side PDB connectors within a chassis. With further downward movement or insertion of the handle, the connectors are then mated. With the handle in a fully downward, inserted, or otherwise latched position with respect to the holder, raised sections of the handle prevent latching teeth or hooks on the cable-side connector from becoming disengaged from the PDB board-side connector, thereby maintaining the connection of the PDB connectors. Uninstallation is the reverse of installation with a single movement of the sliding handle both unlatching and disconnecting the connections.
