2.9.2 I/O Shield
The back panel I/O shield for the board must meet specific dimension and material
requirements. Systems based on this board need the back panel I/O shield to pass
certification testing.
Figure 22 shows the I/O shield for boards with the optional PS/2
connectors.
Figure 23 shows the I/O shield for boards without the optional PS/2
connectors. Dimensions are given in millimeters [inches]. The figure indicates the
position of each cutout. Additional design considerations for I/O shields relative to
chassis requirements are described in the BTX specification.

The I/O shield drawing is for reference only. I/O shields compliant with the BTX
specification are available from Intel.
