The system occupies 1U in the rack. Count the U positions and hole numbers from the bottom up.
The distance from the center of two holes with closer spacing to the center of the next pair is
equivalent to 1U.
When installing components, you must start your measurement from the center of the two holes
with closer spacing. Otherwise, the screw holes on the component may not match with those on
the rack.
The unit of measurement used in this document is “U”
(1U=1.75 inches or 44.45mm). The total sum of the height of
all components in the rack measured in “U” cannot exceed
the height of the rack. For more information, please refer to
the rack’s documentation.
