Installation and Configuration
This chapter describes how to prepare and operate the PXI-1042 Series
chassis.
Before connecting the chassis to a power source, read this chapter and the
Read Me First: Safety and Radio-Frequency Interference
document
included with your kit.
Chassis Cooling Considerations
The PXI-1042 Series chassis are 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
Apertures in the top and along both sides of the chassis facilitate power
supply and module cooling. Air enters through filters and fan inlets in the
lower rear of the chassis and exits through the upper sections on both sides
and through the top, as shown in Figure 2-1. Place the chassis on a bench
top or in an instrument rack so that the fans (air inlets) and the air outlet
apertures along both sides and the top of the chassis have adequate
ventilation. Keep other equipment a minimum of 3 in. away from the air
inlets on the rear of the chassis.
When rack mounting a PXI-1042 Series chassis, provide 1.75 in. (44.5 mm)
clearance above and on the sides of the unit for adequate venting.
High-power applications may require additional clearance.
