3.4Determining the Configuration

The UltraSCSI Hub is used in end–bus SCSI bus configurations only. The SCSI bus segments require TERMPOWER supplied from the remote connection to enable the SCSI Hub port for that segment. Each port on the UltraSCSI Hub has its own terminators.

All SCSI buses are terminated at the physical ends of the bus. This is true even when using a DWZZH UltraSCSI Hub. DWZZH UltraSCSI Hubs are factory set to terminate the SCSI bus. No user configuration of the SCSI terminators is required.

3.5Selecting the SCSI Cables

The StorageWorks Solutions UltraSCSI Configuration Guide describes SCSI cables in detail. When selecting a cable you must consider the cable connector clearance. Be sure to determine the type connector compatible with the controller connector. In some cases you must use a right–angle connector when connecting the cable to the Host Bus Adapter because there is not enough clearance to use a straight connector.
