5.1 Introduction

The following chapter defines the mechanical recommendations of a front-panel interface board.

The definition includes physical raw board size, mounting holes, keep-out zones and recommended

physical tolerances. A compliant front panel interface board can be used in any chassis design that

supports these key features. Figure 23 shows recommended dimensions of the front panel aperture

and interface board placement.

The front panel I/O guideline defines an I/O aperture opening area that is 3.875+/- 0.008 inch

(98.43 +/- 0.20 mm) wide by 1.000 +/- 0.008 inch (25.40+/- 0.20 mm) tall. To retain maximum

flexibility, the exact positioning and configuration of the connectors within the I/O connector zone

is left to the discretion of the designer. The connectors shown in Figure 23 are a reference design

and are shown here only as examples.
