Install the chassis so that you can easily access the rear panel. This
simplifies replacing the air filter or power supply shuttle, if necessary.
Setting Fan Speed
The fan-speed selector switch is on the rear panel of the PXI-1056. Refer
to Figure 1-2,
Rear View of the PXI-1056 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.
