HP StorageWorks Ultrium Full-Height SCSI Tape Drives User Guide (EH853-90905, August 2007)

Attac h power and
SCSI cables
To support the h
igh performance of the tape drive it is important that you connect to a recommended
SCSI bus and use a suitably-rated SCSI cable, see Why is the SCSI bus type important?.
Electrical specifications are as follows.

1. Check your se
rver or HBA d ocumentation to ensure that the SCSI bus and cabling supports the
tape drive’s
bus speeds: Ultra320 for Ultrium 1840 and 960 tape drives, Ultra160 for Ultrium
460 tape drives.
2. Attach the SCSI ribbon cable supplied with the tape drive to the SCSI host bus adapter and connect
it to the SCS
I connector of the d rive, as shown in Figure 8.
3. Attach a sp
are power cable from the server’s internal power supply to the power connector, as
shown in Figure 8.
4. Attach a spare connector on the server’s built-in SCSI bus or HBA’s SCSI ribbon cable to the SCSI
connector
of the drive, as shown in Figure 8.
5. If the dri
ve is the last device on the SCSI chain, make sure that the SCSI cable is terminated c orrectly.
Daisy-chaining two devices is not recommended. If you do so, do not m ix drive families (only
daisy-chain with other Ultrium tape drives) and do not daisy chain any Ultra320 devices. See also
Table 2, “
Supported SCSI bus t ypes.”
