    Note  

    To maintain forced-air cooling for PXI/PXI Express devices, make sure the PXI/PCI chassis fan speed is set to HIGH, the foam fan filters are removed if present, and the empty slots contain slot blockers and filler panels. For more information about cooling, refer to the Maintain Forced-Air Cooling Note to Users.
