Abstract: A latch assembly provides options for the retention within a rack of a chassis, and the retention within the chassis of a device. With the device in a device slot of the chassis, and the chassis installed in the rack, a first latch in a completely extended position prevents the device from being removed from the slot and prevents a latch tooth from being disengaged from the rack. With the first latch in an intermediate position, the latch tooth may be disengaged from the rack and the chassis removed from the rack, but the device may not be fully removed from the device slot. With the first latch in a retracted position the chassis may be removed from the rack and/or the device may be removed from the device slot.

Abstract: An apparatus and system provide coolant temperature data at the individual electronic device level, e.g., for a single server blade, using thermally conductive couplers positioned in-line with one or both of the fluid inlet and outlet tubes and temperature sensors in thermal contact with the couplers. Thus, provided with granular coolant temperature data at the device level, the cooling system, e.g., fan and/or pump speeds, may be controlled with the same level of granularity, thereby improving both temperature control and the conservation of energy.

The pool portion is in fluid communication with the evaporating portion. The pool portion is operable to receive excess fluid of the fluid from the evaporating portion when a volume of the fluid in the evaporating portion is greater than the evaporating volume.

Abstract: An apparatus is provided for completing a blind mate hydraulic connection. A device is equipped at the rear of the device with a shell holding a manifold connected internally to the device cooling system. Clearances between the shell and manifold allow the manifold to rotate in two axes to adapt to a misalignment between the manifold and a rack cooling system. The device is further provided with a cam-handle attached to the front that provides leverage against the rack for overcoming the connection forces of the blind mate. The manifold and cam-handle combine to facilitate disconnecting the device from the rack cooling system from the front of the rack and servicing the device.

Abstract: A fluid control apparatus can include a housing and a drainage hose. The housing can form a chamber operable to receive at least one air vent for a cooling system such that the housing surrounds the air vent and prevents fluid exiting the air vent from passing through the housing. The drainage hose can be fluidly coupled with the housing. The drainage hose can be operable to drain fluid from the chamber of the housing to a drainage tray.

Abstract: A cam latching device is provided for a computing system being installed in a rack. The cam latching device can include a cam and a locking mechanism. The cam includes a handle portion and an engagement portion. The cam includes a locking surface formed thereon. Rotation of the handle portion causes the engagement portion to rotate. The locking mechanism includes a push component and a lock. The push component abuts against a button disposed on a rail of the rack as the computing system translates along a longitudinal axis. When the push component slides against the button, the locking mechanism transitions from a locked configuration to an unlocked configuration. In the locked configuration, the lock abuts against the locking surface to prevent the rotation of the cam. In the unlocked configuration, the lock is retracted away from the locking surface so that the cam is rotatable.

Abstract: A transceiver protection device includes a body operable to be coupled with a cable. The cable is operable to be coupled, via a connector of the cable, to a transceiver. A detach component is operable to receive a detach force to detach the cable from the transceiver. The detach component extends from the body such that the detach component is adjacent to the transceiver when the cable is coupled with the transceiver. A catch component extends from the body. The catch component is operable to be received in an aperture formed by a hanger of the transceiver.

Abstract: A cam system for a liquid cooled computing unit with blind-mate quick disconnects include a cam and a cam guide. The cam guide is operable to engage with the cam. The cam guide includes a bearing guide and a fixed guide. The cam engages first with the bearing guide then engages with the fixed guide to a latched configuration. When the cam engages with the cam guide and transitions to the latched configuration, the cam translates a chassis of the computing unit along a longitudinal axis to blind-mate the quick disconnects.

Abstract: A rack mounted cooling system operable to cool a computing system is provided. The rack mounted cooling system includes a pump unit operable to pump fluid and a plurality of heat exchangers. The heat exchangers include an input heat exchanger and an outlet heat exchanger. The input heat exchanger is operable to receive the fluid from the pump unit, lower a temperature of the fluid, and provide the fluid to a liquid cooled computing unit. The outlet heat exchanger is operable to receive the fluid from the liquid cooled computing unit, lower the temperature of the fluid, and provide the fluid to the pump unit. The heat exchangers are operable to be coupled to a rack of the computing system such that the rack with the plurality of heat exchangers fits within a rack keep in area.

The frame is operable to be a structural component that is substantially coupled to the sled chassis.

Abstract: An elevator provides for sliding and connecting or 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 chassis includes tracks within which travel followers. Motion of the sliding element in a first direction causes the tracks to move with respect to the followers, pulling the device connector away from the mating circuit board connector. In a fully disconnected position, the device may be removed from the slot. Motion of the sliding element in the opposite direction causes the relative motion between the tracks and followers to urge the device connector toward the circuit board connector until, in a fully seated position, the device is connected to the circuit board.

Abstract: An apparatus is provided for forcing a service technician to follow a proper servicing sequence that reduces the potential for an electric shock. Embodiments of the latch mechanism maintain a cable connection unless a tray connector is first disconnected. Embodiments enforce the disconnect sequence using a trigger that is actuated by the disconnecting of the tray connector, a latch-lock in the cable connector that is biased to block a cable connector disconnect mechanism, and a mechanical link between the trigger and the latch-lock. The actuation of the trigger is transmitted by the mechanical link to the latch-lock, which moves in response, unlocking the cable connector and allowing it to be disconnected.

Abstract: A card support is provided that passively and automatically adapts to variations in the length of an electronic card. When a card is inserted into a slotted bar of the card support, variations in the length of that card are adjusted for by the compression or expansion of a spring disposed between the slot and a supporting face.
