Figure 2–20 PVA Module Front Panel
DIGITAL supports enclosure addresses 2 and 3, only for expansion enclosures.
Figure 2-21 defines the SBB device IDs for these two settings of the PVA SCSI
bus address switch. The use of these addresses in combination depends on the
number of enclosures and possible addressing conflicts.
CAUTION
DIGITAL does not support any enclosure address
combination not listed in Table 2-3.
