Cabinets are used to house servers in the equipment room. More types of cabinets are assigned based on their functions and application scope. One of the most commonly used is the 42U standard server opportunity. This article takes you to learn more about the 42U standard server cabinet in the data center.

U identifies the size of the server, is the abbreviation, where the detailed size is determined by the American Electronics Industry Association. Each U is 1.75 inches in height and approximately 44.45 mm.

The cabinet size of the 42U standard server generally complies with the EIA standard, and the width is 19 inches and about 482.6 mm rack track. External width about 23.6 inches about 600 mm. The height is 78.74 inches, and about 2000 mm is the height of the 42U rack unit. Common depths are 39.37 inches about 1000 mm and 41.34 inches about 1050 mm.

The calculation of the space utilization inside the cabinet involves calculating the U number of the cabinet. The total U number of the cabinet must be determined first. The total height of a standard cabinet, such as a 42U cabinet, is 42x 1.75 inches.

Multiply the total height of the cabinet by the height of each U to find the total height of the available space in the cabinet. The height of the devices installed in the cabinet is calculated by adding each device in U units. Calculate the space utilization of the cabinet:

Space utilization =(Used space height/available space height in the cabinet) x 100%

In actual use, it is also necessary to consider factors such as the spacing between devices, heat dissipation space and wiring. These will affect the actual space utilization of the cabinet.

What are the common components in a cabinet? Common components in a 42U cabinet include power sockets, which provide power distribution functions such as 10A, 16A, and 32A, and may also provide lightning protection, surge protection module, indicators, and overload protection. The tray in the cabinet is used to carry and fix the device. The bearing capacity is usually 65kg or more, and it has various types such as fixed and sliding. The cabling ring arranges and secures cables to keep the cabinet clean. Screws and nuts are used for fixing and mounting with M6 specifications. The horizontal cable organizer manages cables and keeps the cables in the cabinet tidy. Fans are used to dissipate heat inside the cabinet and keep the device running at a proper temperature. The optical fiber storage box is used to organize optical fiber cables to keep the cabinet clean. USB socket provides USB connectivity for easy data transfer and device management. The wheel Angle makes it easy to move the cabinet, especially when adjusting the position of the cabinet.

In theory, a 42U cabinet can house 42 1U servers. However, the actual situation may be due to heat dissipation, wiring, moving space and other considerations will be more recommended to place less than 42 units. According to different requirements and configurations, the actual number of 1U servers is between 20 and 40. If 2U or higher U number servers are placed in the cabinet, the number of machines that can be placed will be smaller. Therefore, the specific number of machines that can be placed needs to be determined according to the actual server size and the internal layout of the machine.
