5.2.3 Drawer Installation Method
When installing a Deskpro 4000S or 4000N chassis into a drawer, the following conditions must be
met to ensure proper air flow:
1. There must be 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.
2. There must be 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.
CAUTION: Cable should not be run through the exhaust air hole.
3. There must be at least nine holes ranging in size from 0.38- to 0.50-inches (1.0- to 1.3-cm) in
diameter in the front drawer panel or in the bottom of the drawer in front of the chassis for fresh
air intake.
4. There should be at least one inch of clear space below the drawer to ensure proper air flow if
there are vent holes in the bottom of the mounting drawer.
5. There should also be at least one inch of clear space above the top of the chassis.
