Technical data

• HSZ70 controller A and controller B
• HSZ80 controller A Port 1 (2) and controller B Port 1 (2)
The BN37A-0C is a 30-centimeter (11.8-inch) cable and the BN37A-0E
is a 50-centimeter (19.7-inch) 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:
a. Verify that the fair arbitration switch is in the Fair position to
enable fair arbitration. (See Section 3.6.1.2.2.)
b. Ensure that the W1 jumper is removed to select wide addressing
mode. (See Section 3.6.1.2.3.)
c. 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 that is assigned to the DWZZH-05 port it is
cabled to (12, 13, 14, and 15).

radially connected dual-redundant HSZ70 RAID array controller configured
for transparent failover.
