Intel Desktop Board D850GB Technical Product Specification

2.10.2 I/O Shield
The back panel I/O shield for the D850GB 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 15 shows the critical dimensions of the chassis-dependent 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. See Section 1.3 for
information about the ATX specification.

NOTE
An I/O shield compliant with the ATX chassis specification 2.01 is available from Intel.
