2 Connect the SCSI cable with the adapter to the internal tape drive’s
68-pin SCSI connector.
Checking SCSI Termination 2
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
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.

Note: Be sure the upper 8 data bytes of the 68-pin cable are
properly terminated.
