4.6.2.3 Installing Host Port Cables, Trilinks, and Terminators for HSZ Array Controllers
The following procedure describes how to connect host port cables, trilink
connector blocks, and terminators for HSZ array controllers:
1. Plug the supplied trilink connector block (part number H885–AA) into the
host port connector on the front bezel of the HSZ array controller (if it is not
already in place).
2. Plug the SCSI host port cable into the trilink connector on the front bezel of
the HSZ array controller. Figure 4–10 shows the H885–AA trilink connector
block used for HSZ array controllers.

3. Plug the supplied terminator (68-pin, part number 12–37004–03, Digital
option number H879–AA) into the other connector of the trilink (if this is the
end of the SCSI host port bus).
4. If the host uses an 8-bit single-ended adapter, route the host port cable
from the trilink connector into a DWZZA-series SCSI bus signal converter
(either a 3 ½ inch SBB DWZZA–VA or a desktop DWZZA–AA model with a
self-contained power supply).
If you use a 3 ½ inch SBB DWZZA signal converter, do the following:
• Plug a 3 ½ inch SBB DWZZA–VA signal converter into SCSI slot 0 in a
BA350–SB storage shelf (the DWZZA receives its power from the shelf).
• Plug the SCSI host port cable coming from the controller’s trilink into the
connector on the front of the DWZZA.
• Plug a SCSI–P cable into the first (upper) connector in that BA350–SB
storage shelf.
