Figure 28 SCSI termination in external drives
If you have more than one device on the SCSI bus, daisy-chain them by connecting a cable from the
SCSI-OUT connector on the first device to the SCSI-IN connector on the second device and make sure
that the second device is terminated. (Always use an LVD-rated cable and an LVD-rated or multimode
terminator.)

Removable drives
For HP StorageWorks DAT removable tape drives, termination is provided by connecting a terminator to
the spare SCSI connector on the rear of the tape array. There are two connectors for each bay in the tape
array. It doesn’t matter which is used for SCSI-IN and SCSI-OUT.
If you have each removable drive in the tape array attached to a separate bus, then, for each bay in use,
you must attach a terminator to the spare connector for each device.
If you are using the removable drives to mirror backups, you can daisy-chain devices (but no more
than two on each SCSI bus). Connect an LVD-rated cable from the spare SCSI connector for the first
