Heat ventilation Electromagnetic isolation stront safe Network Rack Cabinet YH2012

Standard cabinets are widely used in computer network equipment, wireless communication equipment, and electronic equipment stacking. Cabinets have the advantages of enhanced electromagnetic shielding, reduced equipment operating noise, and reduced floor area occupation of equipment. For some high-end cabinets, they also have air filtering capabilities. Improve the working environment of precision equipment.

Many engineering-grade devices use a 19-inch panel width, so a 19-inch cabinet is the most common standard cabinet. There are many types and styles of 19-inch standard cabinets, as well as imported and domestic ones. The price and performance gaps are also very obvious. The price of cabinets with the same size and different levels may differ by several times. The user chooses a standard cabinet according to the specific conditions and budget of the installation of stacked equipment to select the appropriate product. The structure of standard cabinets is relatively simple, including basic frames, internal support systems, wiring systems, and ventilation systems. Standard cabinets can be divided into many performance and price grades depending on the type of assembly and materials used. The 19-inch standard cabinet has three general indicators: width, height, and depth. Although the installation width of the 19-inch panel device is 465.1mm, the common physical width of the cabinet is 600mm and 800mm. The height is generally from 0.32--2.0M, and the general cabinet size includes: 0.32 meters, 0.45 meters, 0.6 meters, 1.0 meters, 1.2 meters, 1.4 meters, 1.6 meters, 1.8 meters, and 2.0 meters. It depends on the number of devices in the cabinet and the uniform style. The depth of the cabinet is generally from 350mm-1000mm, which depends on the size of the equipment in the cabinet. Usually, the manufacturer can also customize the product with special depth. The common finished 19-inch cabinet depth is 500mm, 600mm, 700mm, 800mm. The height of equipment installed in a 19-inch standard cabinet is represented by a special unit "U", 1U = 44.45mm. Equipment panels using 19-inch standard cabinets are generally manufactured to specifications of nU (n represents quantity). For some non-standard equipment, most of them can be installed into the 19-inch chassis with additional adapters and fixed.

The materials of the cabinet are closely related to the performance of the cabinet. The materials used for manufacturing 19-inch standard cabinets mainly include aluminum materials and cold-rolled steel sheets. Cabinets made of aluminum materials are lighter and suitable for stacking lightweight equipment and are relatively inexpensive. Aluminum materials are also imported and domestically produced. Due to the difference in texture, there is a certain difference in the physical properties of the manufactured cabinets, especially in larger cabinets. Cabinets made of cold-rolled steel plate have high mechanical strength and large bearing capacity. The thickness and quality of steel sheet used in similar products and the process are directly related to the quality and performance of the product. Some inexpensive cabinets are made of ordinary thin iron plates. Although the price is cheap and the appearance is not bad, the performance is naturally compromised. Usually high-quality cabinets are heavy. 19-inch standard cabinets are generally integrated welding and assembly types. Integrated welding type is relatively inexpensive, welding process and product materials are the key to this type of cabinet, and some inferior products are easily deformed when they are subjected to heavy loads. Assembling type is the most popular form at present. It is loose in packaging, and can be quickly assembled when needed. Moreover, adjustment is convenient and flexible. Some inferior products often have rough interfaces, and they are difficult to assemble and shift. The production level and surface spray process of other cabinets, as well as the fineness of interior partitions, guide rails, slide rails, cabling troughs, and sockets, and the quality of accessories, are also reference standards for the quality of standard cabinets. A good standard cabinet is not only stable but also conforms to the mainstream safety regulations

Fan, and the equipment is installed in a stable, fixed and stable manner. The front and rear doors of the cabinet and the two side panels are well sealed, the equipment inside the cabinet is evenly distributed, and the accessories are abundant, which can be suitable for various applications.

The cabinet body that meets the requirements of the modern core room design usually has the following features.

(1) Ventilation area of ​​the front and rear doors is not less than 5355cm2, meeting the ventilation requirements stipulated by the major server manufacturers.

Meet the requirements of the ventilation area of ​​the cabinet front door

(2) The vertical column can be easily adjusted to meet the requirements of different installation depths.

(3) All devices that comply with the EIA-310-D standard can be correctly installed.

(4) The integrated rear cable management dedicated channel allows users to easily lay, manage, and operate a large number of data cables, even when rack equipment is installed in the cabinet or installed in a cabinet. Easy to complete.

(5) Through the rear power distribution channel, users can easily install multiple types of vertically installed power distribution units (PDUs) without occupying valuable cabinet installation space. Dedicated power distribution channels for convenient power distribution

A larger number of power outlets are provided for cabinet-mounted devices, and no less than 21 IEC power outlets can be provided in the power distribution channel on one side of the cabinet.

(6) The power cables and data cables can be either from the cable tray at the top of the cabinet or from the lower space of the raised floor. Therefore, the top of the cabinet and the bottom of the cabinet need to provide sufficient cables to enter the access port. In some environments, the power cables or data cables may need to be laid out from one cabinet installed side by side to the other cabinet next to each other. Lateral cable channel ports need to be provided on the cabling channels at the rear of the cabinet to meet this requirement. need.

(7) The vertical installation column of the cabinet indicates the exact position of each "U", which eliminates the trouble of the user repeatedly searching for the installation position and greatly facilitates the user's installation work.

(8) The front door, rear door and side panels can be locked and can only be opened with the provided key.

(9) Proven frame design, sturdy standard mounting bars and heavy duty casters provide static and dynamic load ratings of not less than 900kg.

(10) Multiple grounding bolts are provided to provide adequate grounding points for the equipment installed in the cabinet and all independent metal parts.

(11) Front, rear door and side panel designs that can be quickly removed. During equipment installation and routine maintenance, removing cabinet doors or side panels can bring unexpected convenience.
