Fan Mode
The PXIe-1083 chassis operates in two main fan modes.
In Auto mode, the speed of the chassis fans is determined by chassis intake air temperature.
Select Auto mode for improved acoustic performance.
In High mode, the speed of the chassis fans is fixed at high speed regardless of chassis intake
air temperature. Select High mode for maximum cooling performance.
Cooling Profiles
Both fan modes are available within the 38 W and 58 W cooling profiles.
•
38 W cooling profile supports NI modules up to 38 W max power dissipation
•
58 W cooling profile supports NI modules up to 58 W max power dissipation
Note
Refer to Operating Environment requirements in the
PXIe-1083
Specifications
for more information about chassis ambient temperature range and
cooling capacity.
Fan Mode Selection
The chassis fan mode can be selected using Measurement & Automation Explorer (MAX).
Refer to the
Fan Configuration in MAX
section for more information.
Alternatively, the fan mode on the PXIe-1083 chassis is selected using a DIP switch on the
daughterboard. Refer to the
DIP Switches
section for more information about the DIP switch.
Note
The DIP switch must be in the Auto position for software configuration in
MAX to work. If the DIP switch is in the High position, the chassis fan mode will be
High regardless of the software setting.
PXI Express System Configuration with MAX
The PXI Platform Services software included with your chassis automatically identifies your
PXI Express system components to generate a
pxiesys.ini
file. You can configure your
entire PXI system and identify PXI-1 chassis through Measurement & Automation Explorer
(MAX), included with your system controller. PXI Platform Services creates the
pxiesys.ini
and
pxisys.ini
file, which define your PXI system parameters.
Note
The configuration steps for single or multiple-chassis systems are the same.
MAX provides the following chassis information:
•
Asset information, such as serial number or part number
•
Chassis number
•
Voltages, temperatures, and fan speed
•
Fan and cooling settings
