  • Publication number: 20220053669
    Abstract: A heat sink assembly for a cage for a field replaceable computing module includes a heat sink, a thermal interface material (TIM), and an actuation assembly. The heat sink includes a mating surface. The TIM includes a first surface that is coupled to the mating surface and a second surface that is opposite the first surface. Thus, the second surface can engage a heat transfer surface of a field replaceable computing module installed adjacent the heat sink. The actuation assembly includes a shape memory alloy (SMA) element. When the SMA element is in a first position, the second surface of the TIM contacts the heat transfer surface of the computing module. When the SMA element moves to a second position, the second surface of the TIM is moved a distance away from the heat transfer surface of the computing module.

  • Publication number: 20220011056
    Abstract: A heat sink assembly for a cage for a field replaceable computing module includes a heat sink, a thermal interface material (TIM), and an actuation assembly. The heat sink includes fins and a mating surface positioned at a base of the fins. The TIM includes a first surface that is coupled to the mating surface of the heat sink and a second surface that is opposite the first surface. Thus, the second surface can engage a heat transfer surface of a field replaceable computing module installed adjacent the heat sink. The actuation assembly includes a rotational cam. When the rotational cam is in a first position, the second surface of the TIM contacts the heat transfer surface of the computing module. When the rotational cam moves to a second position, the second surface of the TIM is moved a distance away from the heat transfer surface of the computing module.

  • Publication number: 20210410312
    Abstract: A method that includes receiving an indication at a modular electronic system of initiation of online removal for a module removably inserted into a slot of the modular electronic system, increasing a fan speed at the modular electronic system before the module is removed, monitoring an internal temperature at the modular electronic system, and providing an indication that the module is ready for removal upon reaching a specified cooling state at the modular electronic system based on the temperature monitoring. A panel on an adjacent module is opened and extends into the slot upon removal of the module to substantially block airflow bypass from the slot and maintain cooling within the modular electronic system. An apparatus and logic are also disclosed herein.

  • Patent number: 11212937
    Abstract: In one embodiment, a method includes detecting reverse rotation of a fan inserted into a modular electronic system comprising at least one other fan, wherein the reverse rotation of the fan is caused by a back pressure generated by the other fan rotating in a forward direction, applying current pulses to stop reverse rotation of the inserted fan and start rotation of the fan in a forward direction, and operating all of the fans with rotation in the forward direction.

  • Patent number: 11184688
    Abstract: A system includes a tray, where the tray includes a rail and a bracket that secures the rail to a networking device such that the rail is distanced from a surface of the networking device. A support post is removably coupled to the rail. The support post includes a first support member and a second support member vertically displaced from the first support member, where each of the first and second support members includes a support structure that supports a cable connected with a port at the surface of the networking device and routes the cable away from the networking device to another location distanced from the networking device. The cable supported by the first support member is separated and segregated from the cable supported by the second support member. With minimal touch, a support post can be moved from one location to another along the rail.
