Installation and Configuration
Chassis Cooling Considerations
The PXIe-1078 chassis is designed to operate on a bench or in an instrument rack. Regardless of
the configuration, you must provide the cooling clearances as outlined in the following sections.
Providing Adequate Clearance
Caution
Failure to provide adequate clearances may result in thermal related
failures in the chassis or modules.
Apertures in the top, bottom, front, rear, and along the sides of the chassis facilitate power supply
and module cooling, as shown in Figure 2-2. Air for module cooling enters through a fan intake
in the bottom of the chassis. It then exits through the upper sections at the right side and top, as
shown in Figure 2-1. Air for cooling the power supply enters the front and left side of the chassis
and exits through the rear of the chassis, as shown in Figure 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 the back of the chassis have adequate
ventilation. Provide at least 44.5 mm (1.75 in.) clearance above, behind, and on the sides of the
unit for adequate venting, as shown in Figure 2-3. High-power applications may require
additional clearance.
