Here is some key terminology that should be useful for reference purposes:
A RACK UNIT or U (less commonly referred to as RU) is a unit of measure used to describe the height of equipment intended for mounting into a 19-inch rack or a 23-inch rack (The 19-inch or 23-inch dimension refers to the width of the equipment mounting frame in the rack i.e. the width of the equipment that can be mounted inside the rack). One rack unit is 1.75 inches (44.45 mm) high.
The size of a piece of rack-mounted equipment is frequently described as a number in ''U''. For example, one rack unit is often referred to as ''1U'', 2 rack units as ''2U'' and so on.
A typical full size rack is 44U, which means it holds just over 6 feet of equipment.
In computing and information technology, however, half-rack typically describes a unit that is 1U high and half the depth of a 4-post rack (such as a network switch, router, KVM switch, or server), such that two units can be mounted in 1U of space (one mounted at the front of the rack and one at the rear). When used to describe the rack enclosure itself, the term half-rack typically means a rack enclosure that is 24U tall.
A front panel or filler panel in a rack is not an exact multiple of 1.75 inches (44.45 mm). To allow space between adjacent rack-mounted components, a panel is 1⁄32 inch (0.031 inch or 0.79 mm) less in height than the full number of rack units would imply. Thus, a 1U front panel would be 1.719 inches (43.66 mm) high.
A 19-inch rack is a standardized frame or enclosure for mounting multiple equipment modules. Each module has a front panel that is 19 inches (482.6 mm) wide, including edges or ears that protrude on each side which allow the module to be fastened to the rack frame with screws. Equipment designed to be placed in a rack is typically described as rack-mount, rack-mount instrument, a rack mounted system, a rack mount chassis, subrack, rack mountable, or occasionally simply shelf.
A 23-inch rack is used for housing telephone (primarily), computer, audio and other equipment though is less common than the 19-inch rack. The size notes the width of the faceplate for the installed equipment. The rack unit is a measure of vertical spacing and is common to both the 19 and 23-inch (580 mm) racks.
Hole spacing is either on 1-inch (25 mm) centres (Western Electric standard), or the same as for 19-inch (480 mm) racks (0.625 inches / 15.9 millimetres spacing).
