REVIEW THE REAR PANEL DESIGN
The rear panel of the ATLAS _ 800 contains eight slots for housing option
modules which provide a variety of additional resources and data ports. See
Figure 2-1 (AC-powered unit) and Figure 2-2 (DC-powered unit). All slots
are functionally identical, except slots 7 and 8. These two slots can also ac-
commodate an optional power supply for redundancy.
