Installation (and Quick Start)
Installing a Desktop Drive
29
Connecting a SCSI Cable
The desktop LTO-1 and LTO-2 drives have two 68-pin, shielded SCSI interface connectors (ANSI
Alternative 2) on the rear panel (see Figure 14 on page 28). These connectors consist of two rows of
ribbon contacts spaced 2.16 mm (0.085 in) apart. Either connector can be used as a SCSI IN or
SCSI OUT connection. This means you can use either connector to attach the drive to a host com-
puter or to another SCSI device.
1.
Turn off all power to the drive and the computer.
2.
Attach the SCSI interface cable to one of the 68-pin SCSI interface connectors on the back of
the drive (see Figure 14 on page 28).
Checking the SCSI Termination
If the desktop LTO-1 or LTO-2 drive is the last or only device in a SCSI chain, install a terminating
plug on the unused SCSI connector. See Figure 15 on page 29 for two SCSI termination examples.
You can purchase appropriate terminating plugs on the Internet at http://shop.certance.com (U.S.
only).
