Issue Details

The fan in my PXI (or PXIe) chassis is broken or malfunctioning somehow. How can I replace it?


If the fan in your chassis is malfunctioning, you can replace it yourself by following the instruction video for NI PXI(e) 4-, 5-, 6-, and 9-Slot Chassis Fan Replacement. The video demonstrates the fan replacement process on a PXIe-1073, but the general concepts for fan replacement are the same for our different chassis.

Additional Information

Make sure to preventively follow the Best Practices for Building and Maintaining PXI Systems. In particular, make sure to clean chassis fan filters at a minimum interval of six months (if applicable).
