Intel Desktop Board D845PEBT2 Technical Product Specification 2.10.2 I/O Shield The back panel I/O shield for Desktop Board D845PEBT2 must meet specific dimension and material requirements. Systems based on the Desktop Board D845PEBT2 need the back panel I/O shield to pass certification testing. The following figures show the critical dimensions of the three types of I/O shields for the Desktop Board D845PEBT2: • Figure 20 shows the I/O shield for boards with the 6-channel audio subsystem and a back panel 1394a-2000 connector. • Figure 21 shows the I/O shield for boards with the 6-channel audio subsystem and without a back panel 1394a-2000 connector. • Figure 22 shows the I/O shield for boards with the 2-channel audio subsystem. The figures indicate the position of each cutout and give dimensions in inches to a tolerance of ±0.02 inches. 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 2.03 is available from Intel. 22.45 [0.88] 7.01 [0.28] 0.00 11.81 [0.47] 12.04 [0.474] 12.81 [0.504] 14.40 [0.567] 162.30 Ref [6.390] 20.00±0.13 TYP [ 0.79±0.00] 1.00 [0.04] 1.60±0.13 [0.063±0.005] 8X R0.5 MIN 13.19 [0.519] 0.69 [0.027] 11.81 [0.47] 48.00 Ref [1.89] 12.31 [0.485] 14.40 [0.567] 0.00 11.35 [0.45] 30.37 [1.195] 45.89 [1.81] 52.80 [2.08] 84.80 [3.339] 96.69 [3.807] 110.58 [4.354] 125.67 [4.95] 143.12 [5.635] Pictorial View OM15046 Figure 20.
