1. Align the side chassis guide hooks.
2. Slide the chassis cover for about half an inch towards the front until it
fits in place.
3. Tighten the thumb screws.

side and lower side of the chassis cover, make sure all six are
aligned properly in place. Improper chassis installation can
cause the chassis intrusion detector to alarm during POST.
