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).
