The rack unit is a measure of vertical spacing and is common to both the 19 and 23 inch racks.

19-inch rack

The extra width and depth enables cabling to be routed with ease also helping to maintain bend-radius for fibre and copper cables and deeper equipment to be utilised. Although open-frame racks are the least expensive, they also expose air-cooled equipment to dust, lint, and other environmental contamination. A standard inch server rack cabinet is typically 42u in height, 19 inches don Tapping large numbers of holes that may never be used is expensive; nonetheless tapped-hole racks are still cin use, generally for hardware that rarely changes.

Equipment can be mounted either close to its center of gravity to minimize load on its front panelor via the equipment’s front panel holes. Physical Protection, are available, [10] with Zone 4 representing the most demanding environment. Each module has a front panel that is 19 inches As a result, 4-post racks have become common, with such racks featuring a mirrored pair of rear mounting posts.

A pair of rails is mounted directly onto the rack, and the equipment then slides into dim rack along the rails, which support it. Once serial production started, they were built into custom-made racks, one per repeater.

Equipment designed to be placed in a rack is typically described as rack-mountrack-mount instrumenta rack mounted systemdiin rack mount chassissubrackrack mountableor occasionally simply shelf. When in place, the equipment may also then be bolted to the rack. A series of studies led to the adoption of frames 7 feet 2.

A rails kit may include a cable management arm or CMAwhich folds the cables attached to the server and allows them to expand neatly when the server is slid out, without being disconnected. List of International Electrotechnical Commission standards. See also Industrial PC.

For example, an oscilloscope might be 4U high, and rack-mountable computers are mostly between 1U and 4U high. Racks, especially two-post racks, are often secured to the floor or adjacent building structure so as not to fall over.

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. In the event of a nut being stripped out or a bolt breaking, the nut can be easily removed and replaced with a dni one.

Originally, the mounting holes were tapped with a particular screw thread. Larger cases typically have 41944 for easy transport.

Computer servers designed for rack-mounting can include a number of extra features to make cin server easy to use in the rack:. From Wikipedia, the free encyclopedia. The holes in the posts are arranged vertically in repeating sets of three, with center-to-center separations of 0.

The gap between the posts is millimetres Racks carrying telecom equipment like 414494 and switches often have extra width to accommodate the many cables on the sides.

The rails may also be able to fully support the equipment in a position where it has been slid clear of the rack; this is useful for inspection or maintenance of equipment which will then be slid idn into the rack. Portable rack cases using a rotary-molded polyethylene outer shell are a lower-cost alternative to the more durable ATA-approved case.

Heavy equipment or equipment which is commonly accessed for servicing, for which attaching or detaching 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.

The height of the electronic modules is also standardized as multiples of 1. There are a multitude of specialty server racks including soundproof server racks, air conditioned server racks, NEMA rated, seismic rated, open frame, narrow, and even miniature inch racks for smaller applications.
