The dimensions of a 2U standard server cabinet are (482.6mm=19 inches) and height (a multiple of 44.45mm). Because the standard cabinet width is 19 inches, this type of cabinet is usually referred to as a "19 inch cabinet". The height is based on 44.45mm, with 1U being 44.45mm and 42U being 44.45mm/U * 42U=1866.9mm, which is approximately 1.9 meters high. In addition, the cabinet shell occupies a certain height, so the height of the 42U standard cabinet size is 2 meters!

The standard server cabinet of Yifu is 600W * 1200D * 2000H. The cabinet width does not include the size of the outer panel, the depth includes the size of the front and rear doors, and the height does not include the size of the casters and feet. The capacity is 42U.

The number of servers stored in a 42U cabinet is also limited. A 42U standard cabinet does not necessarily mean that it can actually accommodate 42 1U servers. This is because the cabinet takes into account various factors such as reserved space for heat dissipation and movement, power supply, and the need for space for wiring, switches, firewalls, and other equipment on the top and bottom of the cabinet. So usually, a 42U standard cabinet can accommodate around 20 1U servers.

In addition, server cabinets can be classified according to their actual usage size, and their width, depth, and height can be customized to better meet practical needs.
