External drives
For HP StorageWorks Ultrium external tape drives the enclosure provides active termination.
As long as the drive is the only device on the SCSI chain, no terminators are required. The green ACT
Term LED on the rear of the drive indicates whether auto-termination is active (on) or not (off).
Make sure the terminator is firmly attached to the SCSI-OUT connector on the rear of the device when
you install it.
