System rack installation
Aside from its tower configuration, the Altos G701 server system can
also be mounted in a rack-model position. A rack mount kit is
available for customers who want to convert a tower-mounted system
to rack-model design. To purchase a rack mount kit, contact your local
Acer representative or order directly from http://www.acer.com.
The figure below shows the Altos G701 server in a rack-mount position.

Vertical mounting hole pattern
The four vertical rails of a rack contain mounting holes arranged in a
manner shown in the figure below:
The system occupies 5U in the rack. Count the U positions and hole
numbers from the bottom up.
Note: The unit of measurement used in this document 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 your system rack.
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 those on the rack.

Cage nuts are use to secure systems and other components to the
vertical rails in the rack.
To install cage nuts:
1 Insert the lower lip of the cage nut over the bottom of the
opening at the back of a rail.
2 Insert the small end of the cage-nut installation tool through the
opening in front of the rail and hook the tool over the top lip of
the cage nut as shown below.
3 Push in the cage nut while rotating the tool up and pulling the
tool back toward you until the top lip of the cage nut snaps into
position.
