Abstract: An apparatus and system are provided for detecting leaks in cooling tubing using sensor cabling. In the leak detection system, a leak detection cable is routed along the full length of the cooling tube. The leak detection cable and the cooling tubing are encased within a shrunken tube, which leaves such a small gap between the cooling tubing and the heat-shrunk tube that leakage is distributed within the gap about the outside of the cooling tubing by capillary action. The relative position of the detection cable above or below the cooling tubing is then irrelevant, since the capillary action may overcome the effect of gravity and distribute leakage from the bottom of the tubing to a detection cable at the top of the tubing.

Abstract: An apparatus is provided for locking rack-mounted electronic devices within a rack upon removal of one of the electronic devices from the rack. The apparatus includes a shaft rotatably connected to the rack and provided at each slot position with a set of paddles, including a locking paddle and a trigger paddle. With the rack populated with devices, the removal of one device from a slot causes a block attached to the device to urge against a trigger paddle, which rotates the shaft. As the shaft continues to rotate, with the motion of the block caused by the removal of the device, the locking paddle for each slot is rotated into a position such that an attempt to remove any of the other devices from the rack causes the associated block to abut the locking paddle, which does not yield.

Abstract: A carrier is provided for a hard drive. The carrier includes a housing that receives a hard drive and a security chip. A locking component secures the hard drive within the housing. Securing the locking component prevents the hard drive from being removed from the housing. A release mechanism releases the locking component. A breaking component is in communication with the release mechanism such that upon actuation of the release mechanism to release the locking component, the breaking component breaks the security chip for the hard drive.

Abstract: A fan handle is operable to be coupled to a fan. The fan handle includes a first sheet and a second sheet. The first sheet has first apertures operable to receive fasteners to couple a fan guard with a first side of the fan. The first sheet forms a slot. The second sheet has second apertures operable to receive fasteners to couple a fan guard with a second side of the fan. The second sheet forms shoulders from which an extension portion extends. The extension portion is received in the slot of the first sheet. In a retracted configuration, the first sheet and the second sheet are substantially flush such that the shoulders abut against the first sheet. In an extended configuration, the extension portion is partially withdrawn from the slot such that the first sheet and the second sheet are curved and coupled with one another.

Abstract: A method is provided for authenticating firmware images in an embedded system. The method may include loading and executing a trusted firmware using a pre-existing Secure Boot on a baseboard management controller (BMC). The BMC is configured as a master for an embedded system including System On Chips (SOCs) configured as slaves, out-of-band interfaces between the BMC and the SOCs, and flash storages in electrical communication with the SOCs. The method may also include pushing or uploading, by the BMC, a secure SOC firmware image to one of the SOCs using one of the out-of-band interfaces, verifying a digital signature extracted from the SOC firmware image by using a hash code calculated from the SOC firmware image and decrypted using a public key stored on the BMC and notifying a user about verification of the digital signature.

Abstract: An apparatus provides power for computer devices, such as servers, facilitating their testing outside of the typical server rack. A platform of supports the computer device while providing for a power supply unit beneath the platform to be connected to the device. The location of the power supply beneath the platform decreases the combined footprint of the apparatus and device under test. The power supply unit may be configured to connect to standard voltages, allowing the computer device to be tested where connection to rack-level voltage is not convenient.

Abstract: A method is provided for dynamically controlling fan speed of a computing system during boot and reboot. The method may include receiving an ambient temperature from a sensor by a controller. The method may also include controlling speed for one or more fans dynamically based upon the ambient temperature using a dynamic algorithm during boot and reboot of the computing system. The dynamic algorithm may include a function for the fan speed of the one or more fans based upon the ambient temperature.

Abstract: A method and system improve the cooling of computer power supply unit by eliminating a reverse flow of hot air caused by an imbalance in airflow between a power supply fan and a system fan. The method determines a correlation between a system fan speed and a heightened power supply fan speed that prevents the reverse flow of hot air into the power supply unit. During the operation of the power supply unit, the system fan speed is obtained and the heightened power supply fan speed is determined from the correlation. The power supply fan is then controlled using the heightened power supply fan speed setting.

Abstract: An apparatus is provided for loading an electronic device, e.g., a populated GPU board, onto a device tray, e.g., a GPU tray, where the electronic device is cumbersome and the device tray presents obstacles that prevent simply lowering the device into the tray. The apparatus includes a dolly and a base, the base configured to position the dolly against the device tray so that the dolly, carrying the board, may slide the device into position and then be removed from beneath the device.

Abstract: A connection mechanism is provided with a circuit board that replaces internal chassis cabling to multiple electronic devices. In use, the motion of a lever of the connection mechanism drives a carrier of the circuit board in one direction to make an electrical connection at a side of the circuit board. Continued motion of the lever drives the carrier downward to make an additional electrical connections at the bottom of the circuit board.

Abstract: An apparatus and method provide a barrier in the cooling airflow of a component of a computing device that, when the barrier is extended, impedes the airflow, thereby diverting excess cooling airflow from the component to a different component with a different flow path. In response to increased pressure from the airflow, the barrier retracts to permit a greater airflow. Embodiments respond to an increase or decrease in airflow without requiring additional control input and include barriers that deform or pivot in response to increased pressure to permit greater airflow.

Abstract: An apparatus is provided for ensuring the proper orientation of an electronic device within a rack slot. A constraint is added to one of a pair of rail assemblies and a corresponding constraint is added to the rack, the pair of constraints cooperating to allow the pair of rail assemblies to be installed only in the proper sides of the rack. Mounting holes are provided on the device and inner rails of the rail assemblies that allow the inner rail assemblies to be installed only on the proper sides of the device. A key and key slot combination is then provided in an inner rail and a middle rail of one rail assembly with the combination preventing the inner rail from being fully inserted into the incorrect middle rail. Thus, the correct orientation of the device is ensured by the pair of rail assemblies, the spacing of mounting holes in the device, and the rack constraint.

Abstract: An elevator provides for lifting and disconnecting an electronic device from a chassis circuit board and the subsequent removal of the device from a chassis slot. A sliding element between the device and the slot includes tracks within which travel followers associated with the electronic device. Motion in a first direction the tracks causes the tracks to move with respect to the followers, raising the device away from the circuit board. In a fully raised position, the device is disconnected and may be removed from the slot. Motion in the opposite direction causes the relative motion between the track and follower to lower the device toward the circuit board. In a fully seated position, the device is connected to the circuit board.

Abstract: An apparatus is provided for the simultaneous transferring of multiple storage devices from a chassis to reduce service time and associated server temperature fluctuations. The storage transfer device may be mounted to a chassis with a multitude of electronic devices, e.g., a JBOD with HDDs, above the devices to be removed. The storage device may then be manipulated to mechanically unlatch the devices from the chassis and simultaneously attach the devices to the transfer device. The devices may then be disconnected and withdrawn from the chassis and pulled into the storage transfer device. The devices may be re-installed later using the storage device and the reverse process.

Abstract: Embodiments promote the maintenance of a designed flow of cooling air through a chassis during the servicing of one or more electronic components contained by the chassis. A top opening created by the removal of server chassis from a rack may be significantly reduced by internal lids that provide access to groups of components. Gaps created by the partial removal of groups of components may be significantly reduced by air dams attached to the components that inhibit the flow of air between the components. And the opening created by the removal of a circuit board may be significantly reduced by a flap configured to cover the opening upon removal of the circuit board. The various embodiments may be used individually or in combination to reduce openings in the chassis that may allow air to flow in paths that negatively affect the designed air flow.

Abstract: A latch includes a housing, a leaf spring, a tooth, and an actuator. Motion of the actuator against the leaf spring causes the leaf spring to deform and the tooth to extend from the housing to engage a keeper.

Abstract: An interlock system is provided that limits the ability of a user or seismic event to dislodge or partially remove more than one chassis from a rack at any one time. Thus, embodiments reduce the potential for the rack to be toppled by the weight of too many chassis extending from the rack at the same time. The interlock system includes a dynamic rail with locking blocks that move to engage hooks on the rear of the chassis. A trigger at each chassis slot is depressed with installation of a chassis. Upon the removal of any chassis, the associated trigger extends and causes the dynamic rail to be pulled down into a locking position in which the locking blocks engage the hooks on the remaining chassis, which prevents their removal.

The configurable PCI card further comprises a bracket for physically securing the base card to the computing device. The configurable PCI card also comprises a wire layout disposed on the base card for replicating a plurality of different power and heat generation profiles that correspond to a plurality of different chipsets.

Abstract: A carrier of an electronic device is provided with a soft stopper that may maintain the carrier at a service position within a chassis slot. As the carrier is inserted into the slot, at a determined point the soft stopper impinges upon a bumper. Further movement of the carrier into the slot requires the user to force the soft stopper to compress or flex and bypass the bumper. With the chassis slot vertically oriented the soft stopper may maintain the carrier and electronic device in service position, disconnected, while service is performed on a chassis circuit board.

Abstract: A latch includes a cam arm that follows a serpentine groove in the latch handle where curves of the groove create catch positions that define extended and retracted handle positions. In one of the handle positions, an arm of the handle abuts a toothed arm and urges the toothed arm to a latching position in which a tooth is extended. In the other handle position, the arm retracts from the toothed arm, allowing the tooth to retract.
