Abstract: A command-and-control module for communications, ideally in military operating conditions, is adapted for easy insertion into, and removal from, a portable case. A chassis has front and rear vertical plates secured, e.g. welded, to a horizontal plate. At least one DIN rail, for securing electrical and electronic equipment, is mounted to a vertical plate. The case has electrical ports and outlets as well as multiple features to protect the sensitive electronic equipment inside. Shock absorbers between the horizontal plate and the inner surface of the case protect the equipment from mechanical shock. A thermoelectric cooler keeps the equipment from overheating. An inner cover protects the equipment from dust. The inner cover is bolted to the chassis. The chassis is not otherwise affixed to the case. When the bolts are removed, the chassis is easily lifted out by handles.

Abstract: An ethernet bridge mounting arrangement includes a housing including a cover portion and a back portion and a wall mount. The housing is configured to be coupled with the wall mount, and the housing is rotatable relative to the wall mount about an axis that extends in a direction perpendicular to a rear surface of the housing between a first rotational orientation, where latching members extending from the housing can be received by and removed from latch openings in the wall mount, and a second rotational orientation, where the housing is prevented from being pulled away from the wall plate.
