What Components of a Network Cabinet

Mainly including basic framework, internal support system, wiring system, and ventilation system. Standard cabinets can be divided into many performance and price levels based on their assembly form and material selection. The appearance of a 19 inch standard cabinet has three conventional indicators: width, height, and depth. Although the installation width for 19 inch panel equipment is 465.1mm, the common physical widths for cabinets are 600mm and 800mm. The height generally ranges from 0.32 to 2.0M, and the general cabinet dimensions include: 0.32 meters, 0.45 meters, 0.6 meters, 1.0 meters, 1.2 meters, 1.4 meters, 1.6 meters, 1.8 meters, 2.0 meters, etc. It depends on the number and uniform style of equipment inside the cabinet. The depth of the cabinet generally ranges from 350mm-1000mm, depending on the size of the equipment inside the cabinet. Manufacturers can also customize products with special depths. Common 19 inch cabinets have depths of 500mm, 600mm, 700mm, and 800mm. The height occupied by the installation of equipment in a 19 inch standard cabinet is represented by a special unit “U”, where 1U=44.45mm. Equipment panels using 19 inch standard cabinets are generally manufactured according to the specification of nU (n represents quantity). For some non-standard devices, they can mostly be installed into a 19 inch chassis and fixed through an additional adapter board.

The materials used for a network cabinet is closely related to its performance, and there are mainly two types of materials for manufacturing 19 inch standard network cabinets: aluminum material and cold-rolled steel plate. A network Cabinet made of aluminum materials are relatively lightweight, suitable for storing lightweight equipment, and relatively inexpensive. Aluminum materials can also be imported or domestically produced. Due to different textures, the physical properties of cabinets manufactured also vary, especially in larger network cabinets that are more prone to differences. A network Cabinets made of cold-rolled steel plates have the characteristics of high mechanical strength and large load-bearing capacity. The thickness, quality, and process of the steel plate used in similar products are directly related to the quality and performance of the product. Some inexpensive cabinets are made of ordinary thin iron plates, and although the price is cheap and the appearance is good, the performance is naturally greatly reduced. Usually, high-quality network cabinets have a heavier weight.

From the perspective of assembly methods, there are generally integrated welding and assembly types for 19 inch standard network cabinets. The integrated welding type is relatively cheap, and the welding process and product materials are the key to this type of cabinet. Some low-quality products are prone to deformation when encountering heavy loads. Assembly type is currently a popular form, with packaging consisting of loose parts that can be quickly assembled when needed. It is also easy to adjust and has strong flexibility. Some low-quality products often have rough interface parts, making it difficult to assemble and causing significant displacement. In addition, the manufacturing level and surface spray molding process of the cabinet, as well as the precision of internal partitions, rails, slides, wiring slots, sockets, and accessory quality are also reference indicators for measuring the quality of standard cabinets. A good standard network cabinet is not only stable and complies with mainstream safety regulations, but also has stable and fixed equipment installation. The front and rear doors and side panels of the cabinet have good airtightness, and the equipment inside the cabinet is evenly stressed. Additionally, a high quality network cabinet is rich in accessories, which can meet the needs of various applications.
