PXIe-1095 User Manual
Chassis Ambient Temperature Definition
The chassis fan control system uses ambient intake air temperatures for controlling fan speeds
when in Auto mode. These temperatures may be higher than ambient room temperature
depending on surrounding equipment and/or blockages. Ensure ambient intake temperatures do
not exceed the ratings in the Operating Environment section of the PXIe-1095 Specifications.
The module and side ambient intake temperatures can be monitored in National Instruments
Measurement and Automation Explorer (MAX).
Setting Fan Speed
The PXIe-1095 chassis supports multiple fan operating modes. Refer to the Fan Mode section
for more information.
Power Supply Filler Panel
To maintain proper chassis cooling performance a power supply filler panel must be used when
operating with a single power supply. Refer to Replacing the Power Supply in Chapter 3,
Maintenance for more information.
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 the National Instruments website at
ni.com/info and enter the Info Code
slotblocker for more information about slot blockers.
