9.4.3.1 Cabling an HSZ40 or HSZ50 in a Cluster Using External Termination
To connect an HSZ40 or HSZ50 controller to an externally terminated shared
SCSI bus, follow these steps:
1. If the HSZ40 or HSZ50 will be on the end of the shared SCSI bus, attach
an H879-AA terminator to an H885-AA trilink connector.
2. Attach an H885-AA trilink connector to each RAID controller port.
Attach the H885-AA trilink connector with the terminator to the
controller that will be on the end of the shared SCSI bus.
3. If you are using dual-redundant RAID array controllers, install a
BN21-K or BN21L cable (a BN21L-0B is a 0.15-meter cable) between
the H885-AA trilink connectors on the controllers.
4. When the host bus adapters (KZPSA-BB or KZPBA-CB) have been
installed, connect the host bus adapters and RAID array controllers
together with BN21K or BN21L cables as follows:
• Both member systems are on the ends of the bus: Attach a BN21K or
BN21L cable from the BN21W-0B Y cable on each host bus adapter
to the RAID array controller(s).
• RAID array controller is on the end of the bus: Connect a BN21K
(or BN21L) cable from the BN21W-0B Y cable on one host bus
adapter to the BN21W-0B Y cable on the other host bus adapter.
Attach another BN21K (or BN21L) cable from the open BN21W-0B
Y cable connector to the open H885-AA connector on the RAID array
controller.
