Motherboard Description
1.4 I/O Shield
The back panel I/O shield for the AN430TX motherboard must meet specific dimensional and
material requirements. Computers based on this motherboard need the back panel I/O shield in
order to pass certification testing. Figure 3 shows the critical dimensions for the I/O shield and
indicates the position of each cutout. The example shown is chassis-specific and will not
necessarily work with other chassis types.
