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 6-channel (5.1)
audio subsystem. Dimensions are given in inches to a tolerance of ±0.02 inches. The
figures also indicate 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 drawings in this document are for reference only. I/O shields compliant
with the ATX chassis specification are available from Intel.
