Appendix A: Acer Altos R520 rack installation guide154

Vertical mounting hole pattern

The four vertical rails of the system rack contain mounting holes

arranged in a manner shown in the figure below:

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.

Note: The unit of measurement used in this guide is "U"

(1U = 1.75 inches or 44.45 mm). The total sum of the heights of all

components in the rack measured in "U" cannot exceed the

height of the rack. For more information, refer to the

documentation that came with the system rack.

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 those on the rack.
