Installation and Configuration
Chassis Cooling Considerations
The PXIe-1066DC 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
Apertures in the top, bottom, and rear of the chassis facilitate power supply and module cooling.
Air for module cooling enters through a fan intake in the bottom of the chassis and exits through
the top of the chassis. Air for cooling the power supplies enters through the rear of the chassis
and exits through the top of the chassis. Adequate clearance between the chassis and surrounding
equipment or blockages must be maintained to ensure proper cooling of the chassis power
supply as well as the modules plugged into the chassis. These clearances are outlined in
Figure 2-1. The vent locations for the PXIe-1066DC chassis are shown in Figure 2-2. Failure to
provide these clearances may result in thermal-related failures in the chassis or modules.
