Abstract: Embodiments herein describe preventing a pluggable module from connecting to a chassis until ensuring there is no damage on the pluggable module, the chassis, or both. In one embodiment, the chassis includes a blocking element that prevents or blocks the pluggable module from mating with the chassis. The chassis can also include a camera for capturing an image of the pluggable module to determine whether there is damage to its connection elements (e.g., pins). If not, the chassis can release the locking pin to permit the pluggable module to mate with connection elements on the chassis.

Abstract: A rack-mountable heat-exchanger for modular electronic systems is provided that include a heat exchanger including ambient air inlets and outlets forming an ambient airflow path in a first direction, and recirculating air inlets and outlets forming a recirculating airflow path in a second direction perpendicular to the first direction separated from the ambient airflow path; housing for an electronic device, the housing including internal air inlets and outlets forming an internal airflow path; a first duct configured to link the recirculating air outlet to the internal air inlet; a second duct configured to link the recirculating air inlet to the internal air outlet; and fan assemblies located one of the airflow path, configured to propel air through the heat exchanger in the respective airflow path.

Abstract: Embodiments presented in this disclosure generally relate to a ground device. More specifically, embodiments disclosed herein are directed to a grounding device for indicating whether there is proper grounding for electrical equipment. One embodiment presented in this disclosure provides an apparatus. The apparatus generally includes a lug configured to be coupled to a physical ground node, the lug having one or more bolts for coupling the lug to a surface of a plate such that the physical ground node is electrically coupled to an electrical ground node. The apparatus also includes a sensing circuit configured to detect whether the physical ground node is electrically coupled to the electrical ground node, and provide an indication of whether the physical ground node is electrically coupled to the electrical ground node based on the detection.
