Compaq AA-RHGWB-TE - Manual (Page 75)

• HSZ70 controller A and controller B
• HSZ80 controller A Port 1 (2) and controller B Port 1 (2)
___________________ Note ___________________
You must use the same port on each HSZ80 controller.
3. Install the DS-DWZZH-03 or DS-DWZZH-05 UltraSCSI hub in a
DS-BA356, BA356 (with the required 180-watt power supply), or BA370
storage shelf (see Section 3.6.1.1 or Section 3.6.1.2)
4. If you are using a:
• DS-DWZZH-03: Install a BN37A VHDCI to VHDCI cable between
the trilink connector on controller A (HSZ70) or controller A Port 1
(2) (HSZ80) and any DS-DWZZH-03 port. Install a second BN37A
cable between the trilink on controller B (HSZ70) or controller B
Port 1 (2) (HSZ80) and any port on the second DS-DWZZH-03.
• DS-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 or HSZ80
controller A Port 1 (2)
– Install a second BN37A cable between the second DWZZH-05
controller port and the open trilink connector on HSZ70
controller B or HSZ80 controller B Port 1 (2)
5. When the KZPBA-CBs are installed, use a BN38C (or BN38D) HD68
to VHDCI cable to connect the first KZPBA-CB on each system to a
port on the first DWZZH hub. 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).
6. Install BN38C (or BN38D) HD68 to VHDCI cables to connect the second
KZPBA-CB on each system to a port on the second DWZZH hub. 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).

a radially connected dual-redundant HSZ70 configured for multiple-bus
failover.
