4. Attach the HD connection on the SCSI cable to the SCSI-IN co nnector on the rear panel of the tape
drive and secure it by tightening the screws. (See Figure 12.) Do not connect the cable to the
SCSI-OUT connector.
5. The SCSI-OUT connector is only used when daisy-chaining two devices. This is not recommended. If
you do so, do not mix drive families (only daisy-chain with other Ultrium tape drives) and do not put
daisy chain Ultra320 tape drives. See also Table 2.
Does th
e tape drive need a terminator?
If the tape drive is on a dedicated SCSI bus, it does not require a terminator. When the cable is
connec
ted to the SCSI-IN connector, the enclosure provides active termination.
If it is not the only device on the SCSI bus, you must make sure that the SCSI bus is terminated. You
candothisintwoways:
• Place t
he tape drive at the end of the chain and attach the HD connection o n the SCSI cable to
the SCSI-IN connector; the enclosure provides active termination.
• Attach the HD connection on the SCSI cable to the SCSI-IN connector and use the SCSI-OUT
