2.7.3.2 Cabling an HSZ70 to a DS-DWZZH-05 UltraSCSI Hub

To prepare the storage portion of a cluster using HSZ70 RAID array controllers, follow these steps while referring to Figure 2–4 and Table 2–3:

1.Install an H8861-AA trilink connector on each HSZ70 controller port on the SCSI bus segment.

2.Attach an H8863-AA terminator to the H8861-AA connector on the HSZ70 controller that will be on the end of the SCSI bus segment.

3.If there are two HSZ70 controllers, connect the two H8861-AA trilink connectors on the controllers with a BN37A cable.

4.Connect the DS-DWZZH-05 to the HSZ70 H8861-AA trilink with a BN37A cable.
