What is 2U in rack?
This unit has been defined by Electronic Industries Alliance (EIA) as the standard for sizing rack mount equipment. 1 Rack Unit or 1U is 1.75 inches (44.45 mm) high. Systems which are 2U are 2 x 1.75 inches i.e 3.5 inches high and so on. So the effective height of a 2U rack-mount is: 3.5 – (2 x 0.03) = 3.44 inches.
