3. From the back of the rack, attach the library to the rails by inserting an M3
(the two smaller screws) screw into each of the small flanges. Tighten the
screws using a #2 Phillips screwdriver.
CONNECTING TO SCSI
The library communicates with the host through the SCSI interface of the tape
drive(s) via the ADI serial interface. See Figure 1-2 on page 5 for the location of
the tape drive SCSI connectors.
The SCSI interface as seen by the host is the SCSI interface of the tape drive.
The library appears as LUN (Logical Unit Number) 1 on the same SCSI ID as
the tape drive.
 See the tape drive’s Product Manual for tape drive information

This section provides guidelines for connecting the tape drive(s) in the library
to a host system via SCSI. Up to 16 devices can be connected to a wide LVD
SCSI bus.
Note: To ensure optimum tape drive performance, connect the tape drive(s) to
an Ultra3 (Ultra160) SCSI host bus adapter.

! Important
Both LTO-2 and LTO-3 SCSI tape drives are Ultra 160 SCSI
devices and require a minimum Ultra 160 non-RAID SCSI host
bus adapter card, Ultra 160 rated SCSI cabling, and an Ultra 3
Active SCSI terminator.
Caution
Do not connect the tape drive(s) to a high-voltage differential (HVD) SCSI bus.
Doing so may damage the library, tape drive, or other devices on the bus.
