Early network cabinets were mostly made of castings or angle steel connected by screws, rivets, or welded into cabinet frames, plus cover plates made of thin steel sheets as doors. These cabinets were bulky, clumsy, and had simple appearances, and have been eliminated. With the use of transistors, integrated circuits, and the miniaturization of various components and devices, the structure of the cabinet has also developed towards miniaturization and modularization.
The assembly arrangement of the plug-in boxes and plug-ins is divided into horizontal arrangement and vertical arrangement. Network cabinet materials are generally made of thin steel plates, steel profiles of various cross-sectional shapes, aluminum profiles, and various engineering plastics. In addition to welding and screw connections, the frame of the network cabinet also uses bonding processes.
Both network cabinets and server cabinets are 19-inch standard cabinets, which is the common ground between network cabinets and server cabinets!
The difference between network cabinets and server cabinets is that server cabinets are used to install 19' standard equipment such as servers, displays, UPS, and non-19' standard equipment. There are requirements for the depth, height, and weight capacity of the cabinet. The width is generally 600MM, and the depth is generally above 900MM. Because the internal equipment has a large amount of heat dissipation, both the front and rear doors have ventilation holes; network cabinets mainly store routers, switches, patch panels, and other network equipment and accessories.
The network cabinet should have anti-vibration, anti-impact, corrosion resistance, dustproof, waterproof, and anti-radiation performance to ensure stable and reliable operation of the equipment. The network cabinet should have good usability and safety protection facilities, easy to operate, install, and maintain, and can ensure the safety of operators. The network cabinet should be easy to produce, assemble, debug, and package for transportation. The cabinet has an aesthetic, practical, and coordinated color.
