Technical Reference 2.9.2 I/O Shield The back panel I/O shield for the board must meet specific dimension and material requirements.

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.
