19-inch rack

Byit was an established standard with holes tapped for screws with alternating 414944 of 1. 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.

Rack-mountable equipment is traditionally mounted by bolting or clipping its front panel to the rack. Computer servers designed for rack-mounting can include a number of extra features to make the server easy to use in the rack:. A key structural weakness of front-mounted support 441494 the shear stress placed on the mounting rails and the leading edge of the equipment. 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.

End covers are typically secured with either a simple draw latch or a rotary cam “butterfly” latch, named for the shape of the twist handle. List of International Electrotechnical Commission standards. The size denotes the width of the faceplate for the installed equipment.

Ina durable fiber reinforced plastic inch rackmount case was patented by ECS Composites and became widely used in military and commercial applications for electronic deployment and operation.

APC SX-range racksit is common for equipment that features 4-post mounting brackets to have an adjustable rear bracket. Low-wattage devices may not employ active cooling, but use only passive thermal radiation and convection to dissipate heat. 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. The shape of small cases is maintained by the rack rails and the cover seal extrusions alone.

Servers and deep pieces of equipment are often mounted using rails that are bolted to the front and rear posts as above, it is common for such rails to have an adjustable depthallowing the equipment to be supported by four posts, while also enabling it to be dib installed and removed.

The height of the electronic modules is also standardized as multiples of 1. 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 amount of motion and resulting stress depends on the structural characteristics of the building and framework in which the equipment is contained, and the severity of the earthquake.

The next innovation in rack design has been the square-hole rack. Examples include telephone exchanges, ein cabling panels, broadcast studios and some government and military applications.

inch rack – Wikipedia

Retrieved from ” https: The rack unit is a measure of vertical spacing and is common to both the 19 and 23 inch racks. The inch rack format has remained constant while the technology that is mounted within it has changed considerably and the set of fields to which racks are applied has greatly expanded. 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 rin shell is not fiberglass reinforced and is not rigid. Larger cases are further reinforced with dni plywood or sheet metal. A inch rack is a standardized frame or enclosure for mounting multiple electronic equipment modules.

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. dih

For example, an oscilloscope might be 4U high, and fin computers are mostly between 1U and 4U high. This of course varies by manufacturer, the design of the rack and its purpose, but through common constraining factors such as raised floor tile dimensionsthese dimensions have become quite common.

Racks carrying telecom equipment like routers and switches often have extra width to accommodate the many cables on the sides. These cases are marketed to musicians and entertainers for equipment not subject to frequent transportation and rough handling.

The posts are each 0. Road cases are typically made from polyvinyl sin PVC laminated plywood sides, joined by extruded aluminum edging, steel corners, handles and latches. To protect equipment from shock and vibration road rack cases use an inner and outer case. The distance of the right edge of the right mounting rail to the left edge of the left mounting rail is millimetres The posts have holes in them at regular intervals, with both posts matching, so that each hole is part of a horizontal pair with a center-to-center distance of The gap between the posts is millimetres However, not all equipment is suitable for this type of mounting.
