1.11.2 DIGITAL Supported Expansion PVA Addresses
DIGITAL only supports PVA addresses 2 and 3 for expansion enclosures. Figure

address switch, respectively. The use of these addresses in combination depends
on the number of enclosures and possible addressing conflicts.
CAUTION
DIGITAL does not support any PVA address
combination not listed in Table 1-4.
