parts with those that are not direct replacements may cause harm to

Chassis Cooling Considerations
The PXI-1044 is designed to operate on a bench or in an instrument rack.
Determine how you want to use the PXI-1044 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 PXI-1044 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 76.2 mm (3 in.) away
from the air inlets on the rear of the chassis.
When rack mounting the PXI-1044, provide at least 44.5 mm (1.75 in.)
clearance above and on the sides of the unit for adequate venting.
High-power applications may require additional clearance.
