Connecting the enclosures to the cabinet JBs establishes the enclosure address
bus. The enclosures are automatically numbered, based on their physical distance
from the bottom terminator.
The drive enclosure numbers are always assigned by the enclosure address bus.
Connecting the EMU CAB ONLY connector to a enclosure address bus JB
automatically establishes an En of 01 through 14. Any drive enclosure not
connected to the enclosure address bus is assigned an En of 00.
Figure 45 shows the enclosure numbering for a four disk enclosure configuration.
