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.

ÄCAUTION: 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.
