Install the chassis so that you can easily access the bottom panel. This
simplifies replacing the air filters, if necessary.
The AUTO/HIGH fan-speed selector switch is on the rear panel of the
PXI-1031 and PXI-1031DC. Refer to Figure 1-2,
PXI-1031 Chassis, or Figure 1-3,
to locate the fan-speed selector switch. Select HIGH for maximum cooling
performance (recommended) or AUTO for quieter operation. The fan
speed is determined by chassis intake air temperature when set to AUTO.
To improve module cooling performance, install filler panels (provided
with the chassis) in unused or empty slots. Secure with the captive
mounting screws provided.
