Checking SCSI Termination
The internal tape drives do not provide SCSI termination. For this reason, they should not be the last
device on a SCSI chain. Figure 9 on page 30 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 connect a power cable to the internal tape drive:
1. Connect a spare 4-pin power cable from the computer’s internal power supply to the power
connector on the back of the internal tape drive. Figure 10 on page 31 shows the location of
the power connector on the internal tape drive.
The recommended 4-pin power connector for the internal drives is an AMP 1-48024-0 housing, with
AMP 60617-1 pins or equivalent.
