The use of all mounting holes is recommended for proper backplane support. There are two mounting holes on top of the 8-slot PXI backplane that have plated annular pads on the front and back of the backplane. These mounting holes may be used to connect the backplane ground to the chassis in which the backplane is mounted. - Page 3 PXI chassis before removing the backplane from the packaging.
