With the continuous development of network technology and integrated wiring technology, network communication equipment, data center servers and other IT facilities are developing towards racking, networking, and miniaturization. Therefore, the status of cabinets has evolved into a very The important role, take you to learn the basic knowledge of the cabinet today. First, the classification of the cabinet Extended classification: console, monitoring console, tool cabinet, standard cabinet, network cabinet, computer cabinet cabinet, stainless steel cabinet. According to the scope of application: power cabinets, server cabinets, indoor cabinets, communication cabinets, outdoor cabinets, industrial safety cabinets, low-voltage power distribution cabinets. Divided by function: fireproof antimagnetic cabinet, safety cabinet, waterproof cabinet, safe, multimedia console, file cabinet, wall cabinet, power cabinet, monitoring cabinet, shielding cabinet. Second, the concept of capacity "U" The height of the equipment installation in the 19-inch standard cabinet cabinet is represented by a special unit "U". U refers to the effective internal space of the cabinet, 1U=44.45mm. That is, how many U of 19-inch standard equipment can be installed, and the panel of standard equipment using 19-inch standard cabinets is generally manufactured according to the specification of n U. Third, the difference between racks and cabinets They are used to place 19-inch equipment, the load capacity of the 4-post rack is greater than the 2-post rack, the 2-post rack accessories are cantilevered, fixed at 2 points, and the 4-post rack accessories are installed in the same way as the cabinet, 4 points fixed , And the cabinet is closed, which is conducive to the protection of internal equipment; but the rack is open, there are no doors at the front, back, left, and right to facilitate the installation and construction of related equipment, but the dustproofness is relatively poor. Compared with the cabinet, the external environment requires more Higher. Fourth, the difference between network cabinets and server cabinets There are requirements on the depth, height, and load bearing of the cabinet. The width is generally 600MM, and the depth is generally more than 900MM. Due to the large heat dissipation of the internal equipment, the front and rear doors are provided with ventilation holes. The power cabinet cabinet and the server cabinet cabinet are 19 inches. Standard cabinets, server cabinets are used to install servers, monitors, UPS and other 19 "standard equipment and non-19" standard equipment. The network cabinet is mainly used to store network equipment and accessories such as routers, switches, and distribution frames. The depth is generally less than 800MM, and the width is 600 and 800MM. The front door is generally a transparent tempered glass door, which has low requirements for heat dissipation and environment. Fifth, the concept of grounding Grounding includes signal grounding and chassis grounding. The signal grounding function of the equipment is to provide the level reference plane of some or all circuits of the equipment. The ideal grounding plane is a physical entity with zero potential and zero impedance. Any current passes through it. There will be no voltage drop at all times, and the signal ground is usually realized by a dedicated grounding copper bar; The earth connection of the bushing is to realize the safety earthing of the equipment, prevent electric leakage, and realize the safety protection of the operator.

Whether it is a lively card game or a quiet, thoughtful board game, these novelties have been used to polish for hundreds of years. But where to play? Most games are much more comfortable to play on the table, so not long afterwards, aggressive enthusiasts started to make or find a table dedicated to their gaming hobby. Although there must be many examples of ancient game tables, their use did rise in the 18th century, when exquisite game tables were made with etchings, inlays, and paintings carved with the game board itself. Designed for playing on the desktop, they can often double as side tables. 1. Modern game tableNowadays, game tables have adopted clever forms to suit any house decoration. Whether you live in a house full of antiques or prefer the smooth and clean lines of the most modern residence, there is a game table for your space. 2. Folding tableThese watches are very common among people in the 18th century who longed for the middle class. Imagine a table that looks perfectly normal, but with a hinge hidden on one side of the table. Raise the top to expand the table and display the game below. Some of them even include small concave circles to hold drinks or game tokens-even bonuses for specific hands. The folding table has a variety of decoration options and sizes to choose from. 3. Murphy watchYou may have heard of the Murphy bed-it is a bed that folds to the wall when not in use. This technology has been used with many other household necessities, such as ironing boards and even storage racks. So how about the game's Murphy watch? Use the help of the contractor to clarify the placement and appearance after folding. Hanging large pieces of art in this area when not in use may completely hide your table, or you can paint on both sides of the game board to fully express its fun. 4. Rolling tableFamilies who like to play together need a table, which can be moved to any place where there is fun around the house. These tables are placed on four sturdy legs with rollers at the bottom and usually have multiple drawers underneath to accommodate all games and pieces — after all, no one wants to find what they need for a house in this controversial game . These rolling tables are also ideal for taking the game outdoors in the summer evening. 5. Masking tableHave you ever wanted to do something without using a fire pit? Or have you ever wanted the Scrabble game board to stay as it is without leaving any ugly marks or scratches? These masks can work wonders for this.

Do you want your classic motherboard to be always visible? Consider a piece of sturdy glass or plastic that can be cut to your liking to fit the top of your kitchen or living room table. Place the board under it. 6. Classic game room tableSome houses provide more space for sports, and these classics play a role there. There are many options for pool tables, from the most luxurious tables to nodding to streamlined modernist tables. The felt top table is perfect for people who take Texas Hold'em seriously. Do you want to exercise? The interesting table tennis table has every color you can imagine. Create your own game table!Not satisfied with these options?

With the continuous popularity and development of the Internet, computers have become a normal state in the office, and network cabinets have begun to come to our work. If we don't have a network cabinet, a lot of network cables may be scattered in the computer room, and the wires will be everywhere. Therefore, in order to standardize the storage of network lines and wires in the computer room, network cabinets have been promoted and applied, becoming an indispensable network facility in the computer room. What convenience does the appearance of the network cabinet bring to you? Let me give you a detailed introduction below. 1. Line management The emergence of network cabinets can help us to make a reasonable plan for the lines in the computer room. With the network cabinet, we can put some equipment in the cabinet and use the cable management rack to organize the wires or network cables connected to these devices, so that the lines are organized, and the network maintenance staff can quickly find network faults. Make repairs. For network maintenance personnel, the emergence of network cabinets has improved their work efficiency and made work more intuitive. Second, heat dissipation By installing a fan or air conditioner in the network cabinet, the internal network equipment can be kept in a constant temperature working state for a long time. Do not underestimate the impact of this temperature on the network equipment, because the network equipment will generate heat during operation. When many network equipment are stored centrally, the heat dissipation will be large. Many, if the cabinet does not have good heat dissipation capacity, the network equipment may be overheated in the working state, which may cause the equipment to crash and work abnormally, resulting in incalculable losses. 3. Anti-radiation We can know that electronic equipment will generate electromagnetic radiation when it is running, especially in the computer room. Due to the centralized storage of electronic equipment in our country, it will generate electromagnetic radiation. In the long run, it may cause harm to the health of network maintenance workers. Most of the network cabinets are made of metal, such as cold-rolled steel plates. In addition to the benefits of the electromagnetic shielding effect brought by the strong and stable metal materials, the appearance of the cabinet effectively reduces the radiation of the computer room, allowing network maintenance personnel to work without worry. It can be seen that the network cabinet can effectively improve the overall appearance of the computer room; the 19-inch design of the network cabinet can accommodate a large number of network equipment, simplify the layout of the computer room, and improve the appearance of the computer room; it can effectively ensure the reliability and stability of the equipment. The cooling fan can send the heat dissipated when the device is working out of the cabinet to ensure the stable operation of the device. In addition, the network cabinet can also enhance electromagnetic shielding, reduce working noise, and even filter air.   OEM/ODM supports metal indoor rack server network cabinet.
