Installing PXI Filler Panels

Install filler panels, either standard filler panels or EMC panels, over each slot of a PXI chassis that does not contain a module to ensure proper cooling.

Standard filler panels improve the cooling performance of the system; EMC filler panels contain additional gaskets to control EMC emissions from the chassis.

Note Filler panels must be installed over all chassis slots to ensure adequate cooling of modules. To ensure optimal cooling performance, NI recommends using slot blockers in conjunction with filler panels.
  1. Remove the captive screw covers, if present, from the filler panel.
  2. Secure the captive mounting screws to the chassis; for EMC filler panels, ensure that the EMC gasket is on the right side.
    Do not overtighten the screws (2.5 in. · lb maximum).
