Regardless of the configuration, you must provide thecooling clearances as outlined in the following sections.Providing Adequate ClearanceCaution Failure to provide adequate clearances may result in thermal related failures in thechassis or modules.Apertures in the top, bottom, front, rear, and along the sides of the chassisfacilitate power supply and module cooling, as shown in Figure 2-2. Air formodule cooling enters through a fan intake in the bottom of the chassis. Itthen exits through the upper sections at the right side and top, as shown inFigure 2-1. Air for cooling the power supply enters the front and left sideof the chassis and exits through the rear of the chassis, as shown inFigure 2-2.Place the chassis on a bench top or in an instrument rack so that the fans(air intakes) and the air outlet apertures along the right side, the top, and theback of the chassis have adequate ventilation.
