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).
