Drawer Installation Method
When installing the computer chassis in a drawer, the following
conditions must be met to ensure proper air flow:
■ At least 3 inches (7.6 cm) of clear space between the back of the
drawer and anything behind it, such as a wall or the back panel
of a desk.
■ At least two 2-inch (5.1-cm) diameter holes in the back of the
drawer. One hole must be immediately behind the power supply
for exhaust air, and the other should be used for routing the
cables.
Ä
CAUTION: Cables should not be run through the exhaust air hole.
■ At least nine holes in the front drawer panel or in the bottom
of the drawer in front of the chassis for fresh air intake. The
diameter of the holes must be between 0.38 and 0.5 inch
(1.0 and 1.3 cm).
■ At least 1 inch (2.54 cm) of clear space below the drawer to
ensure proper air flow, if vent holes are located in the bottom of
the mounting drawer.
■ At least 1 inch (2.54 cm) of clear space above the top of the
chassis.
