Server cabinets are designed to hold any number of modern rackmount servers. They are usually larger sized cabinets and come in many different heights and in a choice of widths to allow for proper cable management, and in various depths to allow for even the largest rackmount servers to be safely housed.
Network cabinet height is measured in Rack Units or U with 1U being 1.75” (44.445mm) high. The U measurement given is the internal usable size for mounting products into the cabinet. The overall height of the cabinet will therefore be greater than the U height.
This is the overall width of the cabinet. Typically, cabinets are 600mm wide which allows for a small gap at each side of the 19” rackmount products when mounted. 800mm wide cabinets are available to allow for better cable and power management.
Server cabinet depths are 900mm in depth or 1000mm. It is important to ensure that the correct size cabinet is purchased to suit the equipment being mounted. Modern servers can be very deep and heavy and so require the larger size cabinets and are mounted at both the front and the rear within the cabinet.
