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.
_____________________ Note _____________________
The maximum length of a SCSI bus segment, including
cable and internal device SCSI bus length must not exceed
25 meters.
Figure 2–4 shows a sample configuration that uses a KZPBA-CB SCSI
adapter, a DS-DWZZH-05 UltraSCSI hub, and an HSZ70 RAID array
controller.
