Abstract: A cabinet adapted to house electronic and communication equipment therein. The cabinet includes modifiable top, bottom and side walls. Grommets with notches are provided to accommodate passage of wires and cables into and out of the cabinet. The notches function to receive the wires and/or cables and to mitigate passage of air through the grommet. A micro controller is provided for each individual cabinet to both monitor and control variants within the cabinet. The micro controller may be accessed on site with a local operator, or remotely through a memory addressable system.

Abstract: Cabinets or enclosures are provided having heat generating elements stored therein cooled by locating the cabinets on tiles of an elevated floor having cool air provided under the tiles, the cabinets having variable size openings in their bottom surface located over openings in the tiles, openings in the top surface of the cabinets, which openings may have fans located in the openings, highly perforated shelves and a highly perforated front door. By controlling the size of the various openings, and the number, if any, of fans and air flow through the door the temperature in the cabinet may be controlled. A number of cabinets may be located side-by-side with side walls in contact and with wires introduced into one cabinet from under the tiles through an opening in its bottom wall being passed from cabinet-to-cabinet through aligned openings in the side walls of the cabinets.
