Checking SCSI Termination 2
The internal tape drive does not provide SCSI termination. Figure 9
shows two examples of terminating the internal tape drives.
If the drive is the only SCSI device on the bus:
1 Attach it to the next-to-last connector on the SCSI chain.
2 Attach a multi-mode terminator to the last connector in the chain.
This terminator typically is a small, rectangular plastic block that is
marked SCSI Terminator and attaches to the cable.

Connecting a Power Cable to the SCSI Tape Drive 2
To connect a power cable to the internal SCSI tape drive, connect a spare
4-pin power cable from the computer’s internal power supply to the
power connector on the back of the internal SCSI tape drive. Figure 10
shows the location of the power connector on the internal SCSI tape
drive.
The recommended 4-pin power connector for the internal SCSI drives is
an AMP 1-48024-0 housing, with AMP 60617-1 pins or equivalent.
