ATLAS 890 REAR PANEL

The ATLAS 890 rear panel contains 16 slots for housing option modules which provide a variety of
additional resources and data ports (see Figure 4). All slots are functionally identical. The ATLAS 890 also
contains two slots for housing controller modules and a single slot dedicated for power supply use only.
The most common configuration is a fully redundant system with two system controllers and two power
supplies. A fully redundant AC-powered ATLAS 890 provides 13 option slots. A fully redundant
DC-powered ATLAS 890 provides 15 option slots.
