HP StoreEver Ultrium Tape Drives - Manual (Page 26)

Attach power and SCSI cables
To support the high 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 server or HBA documentation 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 SCSI connector of the drive, as shown in Figure 8 .
3. Attach a spare 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 drive is the last device on the SCSI chain, make sure that the SCSI cable is terminated correctly.
Daisy-chaining two devices is not recommended. If you do so, do not mix 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 types.”
