Step 6: Attach power and SCSI cables
To support the high performance of the tape drive it is important to use a suitably-rated SCSI
cable. We recommend that you use the ribbon cable supplied with the tape drive. This
supports up to Ultra 4 (320) bus speeds.
1
Attach a spare power cable from the server's internal power supply to the power connector,
as shown in Figure 7, item 1.
Attach the SCSI ribbon cable supplied with the tape drive to the SCSI host bus adapter or
controller.
2
Attach a spare connector on the server or HBA's SCSI ribbon cable to the SCSI connector of
the drive, as shown in Figure 7, item 2.
3
If the drive is the last device on the SCSI chain, make sure that the SCSI cable is terminated
correctly.
Where should the SCSI terminator be?
Termination must be present at two and ONLY two positions on the SCSI bus—at the
beginning of the SCSI bus and at the end of the SCSI bus. Termination is normally enabled
by default on the HBA and most internal SCSI cables have a terminator attached. This will
usually be a small, rectangular block of plastic attached to the cable end and marked 'SCSI
Terminator'.
Therefore, assuming the HBA is the first device on the bus, you should check that the second
terminator is placed after the last device, as shown in Figure 7, item 2.
