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.

Abstract: The present technology provides minimal touch cable guides for rack-mounted devices. The minimal touch cable guides disclosed herein provide structures for routing cables from field replaceable units installed in a rack mounted device in such a way that cables of different types are not crossed and provides a mechanism for adjusting installed cabling to permit access to otherwise obscured field replaceable units. Such adjustment of cabling is provided in a controlled manner that does not impair the performance the installed cabling.

Abstract: In one embodiment, an apparatus includes an optical module comprising a first end for insertion into a network device and a second end extending from the network device when the optical module is inserted into the network device, and a thermal protective layer extending over a portion of the second end of the optical module, the thermal protective layer preventing direct contact with an external surface of the optical module during removal of the optical module from the network device. The thermal protective layer exposes a portion of the external surface of the second end of the optical module to allow heat to be released from the external surface of the optical module.
