The quality of enclosures and cabinets is directly affected by the quality of the manufacturing process. The steel plate end of the high-tech box is free of burrs, sharp points, burrs, etc. to be cleaned. Because the exposed corners can be folded, the wearer's hands are less prone to injury. The positioning of each card slot is also relatively accurate, with no bracket mounting or offset.
How to judge the quality of chassis and cabinets
1. Look at the steel plate. The steel plate must be thickened. If you tap with your fingers, you can feel what thickness and what kind of thickness.
2. Look at this painting. Qualified cabinets, all steel needs to be painted. The paint must be even. In this way, it prevents rust and dust.
3. From a structural arrangement point of view, there are usually many baffles and cooling holes, so the iron sheet holding the cables should be wrapped to prevent cable damage. The sidewall fans should be mounted on the rear wall of the cabinet, as most of the heat comes from the rear of the unit.
4. From an accessory point of view, since it is an installation that includes network cables, telecommunication cables and power cables, it is necessary to purchase shackle straps or toothed straps in order to effectively secure the cables in the cabinet. If the cabinet has a cable management module, the cables can be fastened directly to the vertical mounting rails.
5, it is more convenient. When looking at glass, the glass should be thick. Also, watch for cracks around the glass. If there are cracks, it means there is danger. Notice the difficulty. Check Out Features: Safety First
7. Watch the heat dissipation and estimate how much heat the device will generate. Generally, there are two to four fans in the ceiling of the cabinet. The more fans the better. There are also screws, nuts, etc. In order to fix the frame, this is enough. The problem of insufficient parts is not caused by future expansion.
Cabinet Type
1 Communication cabinet: A cabinet used for communication.
2. Power cabinet: used for low-voltage power distribution and installation of large control equipment. Various beam and longitudinal beam configurations can be selected for the internal structure. It is a completely modular concept, more vivid and convenient.
The function of the cabinet
The enclosure has three functions
First, it provides space for storage devices such as power supplies, motherboards, various expansion boards, floppy drives, optical drives, and hard drives. In addition, these spare parts are securely fastened inside the case by means of brackets, brackets, various screws and clips. Form a dense whole. Secondly, its sturdy chassis protects circuit boards, power supplies and storage devices, and plays the role of pressure resistance, shock resistance, dust resistance, electromagnetic interference and radiation, and shielding electromagnetic radiation.
Third, it also provides many easy-to-use panel switches, indicator lights, and it makes it easier for the operator to operate the microcomputer and observe the operation of the microcomputer.
