Heat is removed from the IPx Office unit by forced convection. Three DC fans,
mounted on the inside of the right panel, draw cool, ambient air from the left side of
the unit. The cool air absorbs the heat from the circuitry inside of the unit, and is then
expelled through the fans via the right panel. In order for the unit to be cooled
effectively, the
cool ambient air must be drawn in from the left panel, only .
