Installation and Configuration
Chassis Cooling Considerations
The PXIe-1073 chassis is designed to operate on a bench or in an instrument rack. Determine
how you want to use the chassis and follow the appropriate installation instructions.
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 right side of the chassis facilitate power
supply and module cooling. Air enters through a fan intake in the bottom of the chassis for
module cooling. It then exits through the upper sections at the right side, back, and through the
top, as shown in Figure 2-1. Air cooling the power supply enters the front of the chassis, which
is shown in Figure 1-1,

, then exits through the rear of the
chassis, which is shown in Figure 1-2,
Rear View of the PXIe-1073 Chassis
. 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.
High-power applications may require additional clearance.
