Technical Reference 2.10.1 I/O Shield The back panel I/O shield for the Desktop Board D845GVFN must meet specific dimension and material requirements. Systems based on this desktop board need the back panel I/O shield to pass emissions (EMI) certification testing. Figure 12 shows the critical dimensions of the I/O shield. Dimensions are given in inches [millimeters], to a tolerance of ±0.020 inches [0.508 millimeters]. 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. See Section 1.5 for information about the ATX specification.
