32 APEX — Installation and Service Manual
Section 2 — Planning Guide
Space and Ventilation Requirements
The Apex frame requires 11 rack units (19.25 inches) of vertical space and
is approximately 10.3 inches deep. The ventilation system draws cooling
air through openings all along the bottom and in the top third of the left
side. Warm air is exhausted through two fans located in the top right side.
The left and right sides must therefore be kept clear of obstructions. It is not
necessary to leave open space above or below the chassis. See
Figure 2 .
Note Heat-generating equipment must not be mounted beneath the Apex chassis.
