PXI Chassis Recommendations

NI power supplies and SMUs are designed to operate in any PXI-compliant chassis. Temperature rise of the device can vary with slot position in the chassis. Observe the following recommendations to minimize this temperature variation and to ensure normal operating conditions for your device:

• Perform routine maintenance of the chassis cooling fan filters to assure continuous cooling effectiveness and to keep dust off of the device components. NI recommends cleaning the chassis fan filters at a maximum interval of six months and keeping the chassis environment clean to minimize the amount of dust that enters the chassis. For more information about cleaning the chassis fan filters, refer to the documentation for your chassis.
• Install PXI filler panels in all empty slots.
• Verify that the PXI chassis fans that provide forced air remain unobstructed to allow for proper cooling of the PXI chassis, devices, and controller.
