• Keep the ambient temperature as stable as possible.
• Keep the terminal block, module, and chassis in a stable and consistent orientation.
• Install the PXIe filler panels in any unused slots.
• When stacking the system, avoid stacking the chassis above a heat source as heat rises and
can introduce error.
• Allow the thermal gradients to settle after a change in system power or in ambient
temperature. A change in system power can occur when the system powers on. Refer to the
warm-up time in the NI PXIe-4302/4303 Specifications for more information.
• If your PXIe chassis has fan filters, clean or replace them regularly to ensure proper system
cooling. Refer to the PXI/PXI Express Chassis Fan Filter Kit document for more
information.
Note Refer to the Maintain Forced-Air Cooling Note to Users for more
information about maintaining optimal forced-air cooling for PXI/PXI Express
devices.
