Heavy equipment or equipment which is commonly accessed for servicing, for which attaching or rin at all four corners simultaneously would pose a problem, is often not mounted directly onto the rack but instead is mounted via rails or slides. Since the mounting hole arrangement is vertically symmetric, it is possible to mount rack-mountable equipment upside-down.

From Wikipedia, the free encyclopedia. The strength required of the mounting posts means they are invariably not merely flat strips but actually a wider folded strip arranged around the corner of the rack. Two-post racks provide two dim posts.

A inch rack is a standardized frame or enclosure for mounting multiple electronic equipment modules. When rack rails are too thin to tap, rivnuts or other threaded inserts can be used, and when the 414994 class of equipment to be mounted is known in advance, some of the holes can be omitted from the mounting rails. The fans themselves can be difficult to replace. Common uses include server, telecom, broadcast video, lighting, audio, and scientific lab equipment.

The outer shell is frequently embossed in a self-mating cin to combat the tendency for stacked cases to deform slightly creating a slope that encourages the upper case to slide off. Low-wattage devices may not employ active cooling, but use only passive thermal radiation and convection to dissipate heat.

Patent 3,granted June 4, An enclosed sealed cabinet with forced air fans permits air filtration to protect equipment from dust. A third common use for rack-mounted equipment is industrial power, control, and automation hardware.

These posts are typically heavy gauge metal or extruded aluminum. Holes so arranged can either be tapped usually UNF thread, or, less often, 6mm metric or have square holes for dinn nuts. The gap between the posts is millimetres Originally, the mounting holes were tapped with a particular screw thread.

The posts are each 0. The next innovation in rack design has been the square-hole rack.

A difficulty with forced air fan cooling in rack equipment is that fans can fail due to age or di. A series of studies led to the adoption of frames 7 feet 2.

The cases typically use extruded aluminum bands at the ends of the body with tongue-and-groove mating to like bands for the covers. Open Rack is a mounting system designed by Facebook ‘s Open Compute Project that has the same outside dimensions as typical inch racks e.

These aisles may rin be enclosed into a cold air containment tunnel so that cooling air does not travel to other parts of the building where it is not needed or mixes with hot air, making it less efficient.
