The controller can either operate with a BA370 enclosure or with a Model 2200 controller
enclosure combined with Model 4214R, Model 4254, Model 4310R, Model 4350R,
Model 4314R, or Model 4354R disk enclosures.
The controller operates with BA370 enclosures that are assigned ID numbers 0, 2, and 3.
These ID numbers are set through the PVA module. Enclosure ID number 1, which assigns
devices to targets 4 through 7, is not supported. Figure 2–2 shows the addresses for each
device in an extended configuration.
