3.4.3 Standard Cutout for Onboard I/O Ports
The Entry Electronics-Bay Specification includes the I/O aperture of the ATX 2.03 specification
and uses the same dimensions. Because the same dimensions are used, a baseboard manufacturer
can create just one thin metal shield for the rear I/O connectors, a shield that works in any chassis
that meets this specification. This chassis-independent shield closes the Electronics-Bay, except for
small openings that allow access to board-mounted connectors such as, but not limited to, network,
serial, parallel, video, and mouse/keyboard. The shield provides the chassis shielding and
connector grounding that a system requires to meet emissions and susceptibility regulations.
Figure 3-10 shows the Electronics-Bay aperture.
