Setting the PVA Module ID Switch
The Power, Verification, and Addressing (PVA) module provides
unique addresses to extended subsystems. Each BA370 rack-mountable
enclosure in an extended subsystem must have its own PVA ID. Use
PVA ID 0 for the enclosure that contains the array controllers. Use PVA
IDs 2 and 3 for the additional enclosures. Figure 21 illustrates the
PVA settings in an extended subsystem.
See the documentation that accompanied your enclosure for more
details about the PVA and its settings.
