2. Attach the trilink with the terminator to the controller that you want
to be on the end of the shared SCSI bus. Attach an H8861-AA VHDCI
trilink connector to:
• HSZ70 controller A and controller B
• HSZ80 Port 1 (2) of controller A and Port 1 (2) of controller B
___________________ Note ___________________
You must use the same port on each HSZ80 controller.
3. Install a BN37A cable between the trilinks on:
• HSZ70 controller A and controller B
• HSZ80 controller A Port 1 (2) and controller B Port 1 (2)
The BN37A-0C is a 0.3-meter cable and the BN37A-0E is a 0.5-meter
cable.
4. Install the DS-DWZZH-03 or DS-DWZZH-05 UltraSCSI hub in
an UltraSCSI BA356, non-UltraSCSI BA356 (with the required
180-watt power supply), or BA370 storage shelf (see Section 3.6.1.1
or Section 3.6.1.2).
5. If you are using a:
• DWZZH-03: Install a BN37A cable between any DWZZH-03 port
and the open trilink connector on HSZ70 controller A (B) or HSZ80
controller A Port 1 (2) or controller B Port 1 (2).
• DWZZH-05:
– Verify that the fair arbitration switch is in the
Fair position to
enable fair arbitration (see Section 3.6.1.2.2).
– Ensure that the W1 jumper is removed to select wide addressing
mode (see Section 3.6.1.2.3)
– Install a BN37A cable between the DWZZH-05 controller port
and the open trilink connector on HSZ70 controller A (B) or
HSZ80 controller A Port 1 (2) or controller B Port 1 (2).
6. When the KZPBA-CB host bus adapters in each member system are
installed, connect each KZPBA-CB to a DWZZH port with a BN38C (or
BN38D) HD68 to VHDCI cable. Ensure that the KZPBA-CB SCSI ID
matches the SCSI ID assigned to the DWZZH-05 port it is cabled to
(12, 13, 14, and 15).
