The PXI EMC filler panels (National Instruments part number778700-01) must be purchased separately. For more installation information, refer to the NIFlexRIO FPGA Module Installation Guide and Specifications.1. Remove the captive screw covers.2. Install the PXI EMC filler panels by securing the captive mounting screws to the chassis,as shown in the figure below. Make sure that the EMC gasket is on the right side of thePXI EMC filler panel.38 | NI 5791R User Manual and Specifications | ni.com
