Chapter 2
Installation and Configuration
Chassis Ambient Temperature Definition
The chassis fan control system uses intake air temperature as the input for
controlling fan speeds when in Auto Fan Speed mode. Because of this, the
chassis ambient temperature is defined as the temperature that exists just
outside of the fan intake vents on the rear of the chassis. Note that this
temperature may be higher than ambient room temperature depending on
the surrounding equipment and/or blockages present. It is the user’s
responsibility to ensure that this ambient temperature does not exceed the
rated ambient temperature as stated in Appendix A,
. If the
temperature exceeds the stated spec the power switch LED will blink green,
as discussed in the
Power Inhibit Switch LED Indicator
section of this
chapter.
Setting Fan Speed
The fan-speed selector switch is on the rear panel of the NI PXIe-1062Q
chassis. Refer to Figure 1-2,
Rear View of the NI PXIe-1062Q Chassis
locate the fan-speed selector switch. Select
High
for maximum cooling
performance or
Auto
for improved acoustic performance. When set to
Auto
, the fan speed is determined by chassis intake air temperature.
Installing Filler Panels
To maintain proper module cooling performance, install filler panels
(provided with the chassis) in unused or empty slots. Secure with the
captive mounting screws provided.
Installing Slot Blockers
The cooling performance of the chassis can be improved by installing
optional slot blockers. Refer to
ni.com
for more details.
Rack Mounting
Rack mount applications require the optional rack mount kits available
from National Instruments. Refer to the instructions supplied with the rack
mount kits to install your NI PXIe-1062Q chassis in an instrument rack.
Refer to Figure A-3,
NI Chassis Rack Mount Kit Components
Note
You may want to remove the feet from the NI PXIe-1062Q chassis when rack
mounting. To do so, remove the screws holding the feet in place.
