Installation (and Quick Start)
Installing an Internal LTO-1 or LTO-2 Drive
20
Connecting a SCSI Cable
The internal LTO-1 and LTO-2 drives have an Ultra2 SCSI interface, terminated by either a 68-pin
HVD or LVD SCSI connector. Use the following procedure to connect a SCSI cable to this connector.
1.
Turn off all power to the drive and the computer.
2.
Attach the SCSI interface cable to the 68-pin SCSI interface connector on the back of the drive
(see Figure 6 on page 20).

Checking the SCSI Termination
By default, the Internal LTO-1 and LTO-2 drives do not provide SCSI termination. If you use this
default setting, you must place a SCSI bus terminator or a SCSI device with termination enabled at
the end of the SCSI chain. Two examples of SCSI termination are shown in Figure 7 on page 21.
The Internal LTO-1 and LTO-2 drives will provide terminator power if a jumper is placed on the termi-
nation power jumper pins (see “Terminator Power” on page 18).
CAUTION: Install an HVD drive only in an HVD environment and an LVD drive only in an LVD
environment. Look at the label above the drive’s SCSI connector to determine if the drive is an
HVD or an LVD model (see Figure 2 on page 16). Plugging an HVD drive into an LVD bus, or
vice versa, makes the entire bus non-functional and may permanently damage the drive or other
SCSI devices on the bus.
