Computer servers designed for rack-mounting can include a 60297-11 of extra features 600297-1 make the server easy to use in the rack:. For rack mounted computer servers, devices generally intake air on the front and exhaust on the rear. This is usually required by local building codes in seismic zones. A pair of rails is mounted directly onto the rack, and the equipment then slides into the rack along the rails, which support it.

The earliest repeaters from were installed in ad-hoc fashion on shelves, in wooden boxes and cabinets. These posts are typically oec gauge metal or extruded aluminum. The distance of the right edge of the right mounting rail to the left edge of iwc left mounting rail is millimetres All Wikipedia articles needing words, phrases or quotes attributed Wikipedia articles needing words, phrases or quotes attributed from November Commons category link is on Wikidata.

Installation and removal of hardware in a square hole rack is very easy and boltless, where the weight of the equipment and small retention clips are all that is necessary to hold the equipment in place. The fans themselves can be difficult to replace. This prevents circular airflows where hot exhaust air is recirculated through an adjacent device and causes 60297-11.

The cases typically use extruded aluminum bands at the ends of the body with tongue-and-groove mating to like bands for the covers.


APC SX-range racksit is common for equipment that features 4-post mounting brackets to have an adjustable rear bracket. These cases can be isolated by thick layers of foam or may use spring-loaded shock mounting.

inch rack – Wikipedia

Non-isolated cases simply mount inch mounting rails inside 6029-71 case. In the event of a nut being stripped out or a bolt breaking, the nut can be easily removed and replaced with a new one.

Nineteen-inch racks in two-post or four-post form hold most equipment in modern data centersISP facilities, and professionally designed corporate server rooms.

By using this site, you agree to the Terms of Use and Privacy Policy. Nineteen-inch racks are also often used to house professional audio and video equipment, including amplifierseffects unitsinterfaces, headphone amplifiers, and even small scale audio mixers. See also Industrial PC. A difficulty with forced air fan cooling in rack equipment is that fans can fail due to age or dust. According to Telcordia Technologies Generic Requirements document GRCORE, during an earthquake, telecommunications equipment is subjected to motions that can over-stress equipment framework, circuit boards, and connectors.

Although open-frame racks are the least expensive, they also expose air-cooled equipment to dust, lint, and other environmental contamination.

To protect equipment from shock and vibration road rack cases use an inner and outer case. Ina durable fiber reinforced plastic eic rackmount case was patented by ECS Composites 602971 became widely used in military and commercial applications for electronic deployment and operation.

Production of clearance-hole racks is less expensive because tapping the holes is eliminated and replaced with fewer, less expensive, cage nuts. Since the mounting hole arrangement is vertically symmetric, it is possible to mount rack-mountable equipment upside-down.

Two-post racks provide two vertical posts. Equipment designed to be placed in a rack is typically described as rack-mountrack-mount instrumenta rack mounted systema rack mount chassissubrackrack mountableor occasionally simply shelf. When rack rails are too thin to tap, rivnuts or other threaded inserts can be used, and when the particular class of equipment to be mounted is known in advance, some of the holes can be omitted from the mounting rails.


Four-post racks allow for mounting rails to support the equipment at the front and rear. A rack’s mounting fixture consists of two parallel metal strips also referred to as “posts” or “panel mounts” standing vertically.

Physical Protection, are available, [10] with Zone 4 representing the most demanding environment. The posts are each 0.

19-inch rack

The inch dimension includes the edges, or “ears”, that protrude on each side which allow the module to be fastened to the rack frame with screws. In contrast 6297-1 the “inch world”, ETSI also defined the size of the rack enclosure: 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. For example, an oscilloscope might be 4U high, and rack-mountable computers are mostly between 1U and 4U high.

A blade server enclosure might require 10U. The First Stored Program Computer. Heavy equipment or equipment which is commonly accessed for servicing, for 602971 attaching or detaching at all four corners simultaneously 6097-1 pose a problem, is often not mounted directly onto the rack but instead is mounted via rails or slides.

When in place, the equipment may also then be bolted to the rack.
