CHAPTER 4: Installing Your Tape Drive
Pin assignments for the three possible SCSI connectors are listed in a series of
tables: Multimode Single-Ended (MSE) Single Ended (SE) mode in
Table 4-2 on
page 4-14 , MSE Low Voltage Differential (LVD) mode in Table 4-3 on page 4-16 ,
and High Voltage Differential (HVD) mode in Table 4-4 on page 4-17 . Pin
assignments for the power connector are listed in Table 4-5 on page 4-19 .
1.
Prior to connecting the SDLT drive to the host computer, make sure the drive
and computer are turned OFF.
2. If you are connecting several devices to the SCSI bus, connect only the drive
to the host computer at this time. Confirm that the host computer and drive are
communicating correctly before adding additional devices.
3.
The SCSI bus must be terminated at each end. This drive may need to be
terminated:
!
if the SDLT drive is the only device connected to the SCSI bus, OR
!
if the SDLT drive is one of several devices connected to the SCSI bus,
and it is the last device connected to the SCSI bus.
4. If the answer to step 3 was affirmative, attach a “Y” connector to the drive’s
SCSI connector; then attach the SCSI cable to one leg of the “Y” and attach
the terminator to the other leg. Carefully connect the cables, to avoid bending
or damaging the connector pins.
5.
Attach the power cables to the drive. Check the SCSI cable and termination
connections and ensure that they are attached correctly and seated firmly.

Optional Loader Connector
The 8-pin optional loader connector provides signals to be used when the tape
drive is part of a loader/library configuration.
Figure 4-6 on page 4-14 shows the
location of this connector; pin assignments for the loader connector are listed in
Table 4-6 on page 4-19 .
