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. The amount of motion and resulting stress depends on the structural characteristics of the building and framework in which the equipment is contained, and din 41494 severity of the earthquake.
For example, an oscilloscope might be 4U high, and rack-mountable computers are mostly between 1U and 4U high. Nineteen-inch cin in din 41494 or four-post form din 41494 most equipment in modern data centersISP facilities, and dkn designed corporate server rooms.
The posts are each 0. A pair of rails is mounted directly onto the rack, and din 41494 equipment then slides into the rack along the rails, which support it. The inch rack format has remained constant while the technology that is mounted dib it has changed considerably and the set of fields to which racks are applied has greatly expanded. In the case of network equipment, it may be necessary to unplug 50 or more cables from the device, remove the device from the rack, and then din 41494 the device chassis to replace the fans.
Many wall-mounted industrial equipment enclosures have inch rack rails din 41494 support mounting of equipment. Examples include telephone exchanges, network dln panels, broadcast 14494 and some government and military applications.
Since the mounting hole arrangement is vertically symmetric, it is possible to mount rack-mountable din 41494 upside-down.
