2.10.2 I/O Shield
The back panel I/O shield for the boards must meet specific dimension and material requirements.
Systems based on these boards need the back panel I/O shield to pass certification testing.
Figure 21 shows the I/O shield. Dimensions are given in inches to a tolerance of ±0.02 inches.
The figure also indicates the position of each cutout. Additional design considerations for I/O
shields relative to chassis requirements are described in the ATX specification.
NOTE
The I/O shield drawing in this document is for reference only. An I/O shield compliant with the
ATX chassis specification 2.03 is available from Intel.
