Tip Install the chassis so that you can access the rear panel easily. This simplifies cleaning
or replacing the air filters.
Setting Fan Speed
The fan-speed selector switch is on the rear panel of the PXI-1052. Refer
to Figure 1-2,
Rear View of the PXI-1052 Chassis , 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.
Installing Filler Panels
To improve module cooling performance, install optional PXI filler panels
in unused slots. Secure the panels with the captive mounting thumbscrews
provided. You can obtain these panels through NI.
Installing Slot Blockers
You can improve the cooling performance of the chassis by installing
optional PXI slot blockers. Visit
ni.com/support to read the
NI KnowledgeBase article 2S4928ON, PXI Slot Blockers and
Improved PXI System Cooling Performance, for more details.
Rack Mounting
Rack-mount applications require one of the optional rack-mount kits
available from NI. Refer to Figure A-3,
PXI-1052 Rack Mount Kit
Components , and the instructions supplied with the rack-mount kits to
install the PXI-1052 in an instrument rack.
Note You may want to remove the feet from the PXI-1052 when rack mounting. To do
so, remove the screws holding the feet in place.
