1. Racks are marked in vertical increments of 4.45 cm (1.75 inches). Each
increment is referred to as a unit, or “U.” A 1-U-high device is 4.45 cm (1.75
inches) tall.
2. Power consumption and heat output vary depending on the number and type of
optional features installed and the power-management optional features in use.
3. These levels were measured in controlled acoustical environments according to
the procedures specified by the American National Standards Institute (ANSI)
S12.10 and ISO 7779 and are reported in accordance with ISO 9296. Actual
sound-pressure levels in a given location might exceed the average values
stated because of room reflections and other nearby noise sources. The
declared sound-power levels indicate an upper limit, below which a large
number of computers will operate.
