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.

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.

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.

Abstract: In one embodiment, an apparatus is disclosed comprising a cable management bracket and a cable guide connector configured to engage a slot of a networking chassis having a length extending along a first axis. The cable guide connector comprises a center section configured to slide within the slot along the first axis and having an aperture configured to receive a retainer to secure the cable guide connector by compression at a selected position along the length of the slot. The cable guide connector further defines a plurality of apertures configured to engage a protrusion of the cable management bracket and defines a plurality of selectable angles at which the cable management bracket can be positioned relative to a second axis that is perpendicular to the first axis through which the slot extends.

Abstract: Techniques are provided herein for dynamic pressure control of a heat sink. In one example embodiment, an apparatus includes a Ball Grid Array (BGA) device, a heat sink thermally coupled to the BGA device, and a pressure control assembly configured to dynamically control a pressure of the heat sink on the BGA device based on a temperature associated with the BGA device. The pressure control assembly includes a Shape Memory Alloy (SMA) washer configured to apply a first amount of the pressure when the SMA washer is in a first state, and a second amount of the pressure when the SMA washer is in a second state.
