Maintenance of telecommunications equipment and electronic equipment in general often requires the use of special tools. This is especially true for server rooms, technical rooms and control rooms, the functional purpose of which involves the installation of IT devices. Helps in solving this problem mounting rack, provided with reliable supporting and mounting fittings.
Technical device
This design looks like a cabinet or a multifunctional set of compact shelving. For example, server cabinets perform the same tasks, but their device includes the inclusion of doors and windows. In turn, the rack is an open structure without sheathing and locking panels. This is a frame assembled from metal (usually steel) elements, brought together with hardware. In height, such a design can reach 2200 mm, in width - 500 mm, and in depth - about 1000 mm. Moreover, there are non-standard form factors designed to service specific equipment - air conditioners, uninterruptible power supplies, mini-stations, etc. All profile elements that make up the mounting rack are perforated, as well as sockets and outlets for connecting to third-party equipment or power supplies.
Equipment set
The design of the rack itself is quite simple, but thanks to the included in the basic set or additional fittings, it can be very functional. The main kit usually includes support elements (legs, wheels or platform carrier base), frames with profiles directly, fixing parts and a cover. Separately, as an option, skids and shelves are purchased in accordance with a given standard size. The shelving elements themselves can have a different principle of operation - from manual to automatic with guide skids and an electric drive. It is important to take into account the possibility of transforming the body. The Advanced Rack Mount Kit may include adjusters and adapter modules that allow the user to connect the cabinet to other similar installations.
Varieties of racks
In the simplest models, the construction is carried out with one frame. This is an optimized option, which implements the minimum physical support of the equipment on the one hand. Moreover, in the lower part of the fixation, the possibility of shifting is provided.profiles. That is, the owner can adjust the design according to the depth of the target equipment. A two-frame mounting rack is more common, in which there are two fixing sides. This design increases the ability to withstand heavy loads and expands the functionality. Unlike single-frame models, these versions allow you to place intermediate shelves and niches, providing fixation on four sides. Also in terms of material stiffness, double-frame structures show higher rates. Hardened steel is often used, additionally treated with anti-corrosion and anti-static coatings.
Performance Features
Telecommunication equipment racks have many advantages over server cabinets and storage racks.
First of all, it is a small mass and a minimum of structural elements. Even when assembled with a complete set, such an installation can be easily carried by one person - the average weight is 10-15 kg. At the same time, the load capacity varies from 300 to 800 kg.
The second feature, due to structural minimalism, is the unification and flexibility of use in solving a wide range of tasks. A standard mounting rack, provided that the appropriate shelves and fasteners are used, is equally suitable for large cases of server equipment, and for compact devices such as routers, distributors and electrical fittings.
Also, compared toindustrial furniture for storage, racks of this type are specially oriented for the operation of electronics. This is evident in the smallest details - from the channels for wiring of various sizes to plastic jumpers that allow you to securely fix the circuits, providing grounding.
Installation of mounting racks
At the first stage, metal frames are assembled. By means of complete clamps, clamps and fasteners, the base body is constructed. The bottom panel is connected to the corner posts, and a cover is mounted in the upper part. As a rule, butt joints are brought together with screws, brackets and bolts of a suitable size. The installation is carried out in an initially thought out place, and it does not have to be a stationary use of the equipment. The same versions with wheels can be moved by temporarily fixing the frame with clamps. At the next stage, the target equipment is placed. First, cabinets and racks are adjusted to the equipment enclosures, and then secured.
Additional profiles with bolt holes are practically not used - the main perforation gives enough room for precise fitting of equipment cases. The integral latches can be fitted with M6 square nuts that secure the main bodies. From the back, it is provided for fastening the edges of the equipment and mounting the retractable rails.
Conclusion
The use of special devices for electrical equipment facilitates the processes of its operation, technicalmaintenance and storage. Also, the use of a mounting rack increases the level of safety. For the same server rooms and data centers, there are high requirements for fire safety standards. Even an average carrier rack infrastructure provides an optimal level of electrical protection that prevents the risk of short circuits and network overloads. And this is not to mention the possibilities of convenient integration into the same working compartments of fuse blocks and automatic load distributors.
