Installation and Configuration
Chassis Cooling Considerations
The NI PXIe-1085 Series chassis is designed to operate on a bench or in an instrument rack. The
chassis must be oriented horizontally for benchtop use. Vertical orientation with the chassis
handle up is not a supported configuration. Regardless of the configuration, you must provide
the cooling clearances as outlined in the following sections.
Providing Adequate Clearance
The primary cooling exhaust vent for the NI PXIe-1085 Series is on the top of the chassis. The
primary intake vent is on the rear of the chassis. The secondary intake and exhaust vents are
located along the sides 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 NI PXIe-1085 Series chassis are shown in Figure 2-2.
Failure to provide these clearances may result in thermal-related failures in the chassis or
modules.
