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.
