Intel Desktop Board D845HV/D845WN Technical Product Specification 2.10.3 I/O Shield The back panel I/O shield for D845HV and D845WN boards must meet specific dimension and material requirements. Systems based on this board need the back panel I/O shield to pass certification testing. Figure 19 shows the critical dimensions of the chassis-dependent I/O shield for boards with the onboard LAN subsystem. Figure 20 shows the critical dimensions of the I/O for boards without the onboard LAN subsystem. 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 1.4 for information about the ATX specification. NOTE The I/O shield drawings in this document are for reference only. An I/O shield compliant with the ATX chassis specification 2.01 is available from Intel. 0.884 [22.450] 0.276 [7.012] 0.00 0.465 [11.811] 0.567 [14.400] 6.390 Ref [162.300] 0.787±0.010 TYP [20±0.254] 0.039 Dia.
