Abstract: A technique and corresponding device to provide for a floating heat sink is disclosed. The technique includes a method that allows for insertion of an electronic component (e.g., an optical transceiver) into a cage that has a pre-installed heatsink. At the beginning phases of insertion, no friction is present between the electronic component and the heatsink. At or very near an insertion end phase (the electronic component is almost fully inserted), an actuator (e.g., roller or button) is impacted to impart a pivot motion via a lever arm to cause lowering of the heatsink toward the electronic component. A thermal interface material (TIM) may therefore be present to establish a thermal coupling between the heatsink and the electronic component. The TIM and heatsink contact the electronic component via a downward motion (caused by the pivot) to provide a nearly frictionless sliding impact to the TIM.

Abstract: A chassis for an electronic device includes a tray and a frame. The tray is removably coupled to the frame and includes engagement members to engage with complementary engagement members of electronic modules mounted to the tray. The engagement members include pairs of engagement members disposed adjacent to each other on the tray. The engagement members in each of a first pair and a second pair are spaced apart from each other by a first distance. The first pair and the second pair of engagement members are spaced apart from each other by a second distance different from the first distance. The engagement members are configured to allow for mounting of a first electronic module having a first width to the tray and to allow for mounting of a second electronic module having a second width to the tray, where the second width is different from the first width.

Abstract: Examples discussed herein relate to managing power allocation for devices, such as network devices, with processing chip. In some examples, based on determining that a first temperature measurement of the processing chip does not satisfy an operating temperature threshold, the network device allocates power from a power source to a first heating element of the network device to heat the processing chip & allocates power from the power source to a second heating element of the network device to heat the processing chip. Based on determining that a second temperature measurement satisfies the operating temperature threshold, the network device allocates power from the power source to a set of power over ethernet ports of the network device & the first amount of power from the power source selectively to the first heating element to heat the processing chip.

Abstract: Example implementations relate to an insertion key assembly for a pluggable module. The insertion key assembly includes a stopper element having a stopping tab, a biasing element, and a driver element having a driving tab. The biasing element is connected to the stopper element and the driver element. In a relaxed state of the biasing element: i) the stopper element is pushed outwards by the biasing element to protrude the stopping tab into a passageway defined by a plurality of walls of a chassis, to block insertion of the pluggable module inside the passageway, and ii) the driver element is pushed outwards by the biasing element to protrude the driving tab into adjacent passageway. In a biased state of the biasing element, the stopper element is pulled inwards by the biasing element to retract the stopping tab from the passageway to allow insertion of the pluggable module inside the passageway.

Abstract: An information processing device comprises heat generating components, a plenum, and fans arranged to flow air through the plenum and to cool the heat generating components. The device also comprises a recirculation inhibition mechanism to reduce the amount of air recirculation in the event a fan fails. The recirculation inhibition mechanism comprises a plenum impedance element extending across the plenum such that the air passing through the plenum passes through the plenum impedance element prior to reaching the fans, and dividers disposed in the plenum and defining sub-compartments in the plenum. Each of the sub-compartments corresponds to one of the fans and is configured to supply air to or receive air from the corresponding fan. In the event of one of the fans failing, air recirculating through the failed fan passes though the plenum impedance element twice before reaching an adjacent fan.
