REVIEW THE REAR PANEL DESIGN
The ATLAS 810
PLUS
rear panel contains eight slots for housing option mod-
ules which provide a variety of additional resources and data ports. All slots
are functionally identical except slots 7 and 8, which can also accommodate
an optional power supply for redundancy. See Figure 2-1 (AC powered unit)
