tape drive to the same bus as a RAID controller. For optimum
performance, we recommend that your DAT drive is installed on a
dedicated SCSI bus. If it is not, do not connect it to the same bus as
your disk drive.

Perform a normal system shutdown and turn off the server and any
connected peripherals.
3.
Attach the VHD connection on the SCSI cable to the server's external
SCSI connector and secure it by tightening the screws.

4.
Attach the HD connection on the SCSI cable to one of the SCSI
connectors on the rear panel of the tape drive and secure it by tightening
the screws.
5.
Connect the LVD terminator to the drive's other SCSI connector and
tighten the screws to secure it.
Why does the tape drive need a terminator?
Terminators are essential, as they provide the correct voltages on the SCSI
bus and prevent unwanted signal reflections from interfering with data
transfers. The rule is:
There must be termination at both physical ends of the bus and only
at the ends.
Normally the HBA forms one end of the SCSI bus and provides termination.
You, therefore, need to ensure that the other end of the bus is terminated.
If the tape drive is at the end of the SCSI bus, the terminator must be
attached to the tape drive.
If you want to attach additional devices to the SCSI bus after the tape drive,
you will need to remove the SCSI terminator and attach the next device to
