5.6.4REMAINING SPACERS

When finished installing the modules, reinstall any remaining spacers.

5.6.5INSTALLING BLANK BACK PANELS

The space above the last module installed must be filled with blank back panels for the following reasons:

•To provide a safe unit

•To ensure proper air flow over the modules

•To keep excessive dirt or contamination out of the unit

To be in compliance with radiated emission standards such as FCC Part 15 and FTZ.

To install, first locate the top side of the panel. The top side is identified by the dimples on the surface of the panel (Figure 5-14). Place the blank panel on the outside of the unit, aligning the two screw holes. The action of screwing in the screws will bring the holes into perfect alignment and will cause the blank back panel to fit snugly against the back panel beneath it. The screws should be snug but not so tight as to strip the threads.
