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.”
