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: 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.

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.

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.
