Install the chassis so that you can easily access the rear panel. This
simplifies replacing the air filters or power supply shuttle assembly,
if necessary.
Setting Fan Speed
The fan-speed selector switch is on the rear panel of the PXI-1042 Series
chassis. Refer to Figure 1-2, Rear View of the PXI-1042 Chassis, and
Figure 1-3, Rear View of the PXI-1042Q Chassis, to locate the fan-speed
selector switch. Select HIGH for maximum cooling performance
(recommended) or AUTO for quieter operation. When set to AUTO,
the fan speed is determined by chassis intake air temperature.
Installing Filler Panels
To improve module cooling performance, install filler panels (provided
with the chassis) in unused or empty slots. Secure with the captive
mounting screws provided.
