SCSI and Power Connectors
Figure 4-6 on page 4-13 shows the pin orientation for the 68-pin SCSI connector and 4-pin power
connector located on the back of the internal tape drive.
The tables list pin assignments for the two possible SCSI connectors: Multi-mode Single-Ended
(MSE)/Single Ended (SE) mode in
Table 4-3 on page 4-13 , and MSE Low Voltage Differential (LVD)
mode in Table 4-4 on page 4-15 . Pin assignments for the power connector are listed in Table 4-5 on
page 4-16 .
1. Before connecting the SDLT 600 tape drive to the host computer, be certain the tape drive and
computer are powered off.
2. Ensure that your SCSI cables and terminators are SPI-3 (or SPI-4) compatible. SPI refers to SCSI
Parallel Interface; you can learn more about this standard at the web site http://www.t10.org .
3. If you are connecting several devices to the SCSI bus, connect only the tape drive to the host
computer at this time. Confirm that the host computer and tape drive are communicating correctly
before adding additional devices.
4. The SCSI bus must be terminated at each end. You may need to terminate this tape drive if one of
the following conditions exist:
 The SDLT 600 tape drive is the only device connected to the SCSI bus.
 The SDLT 600 tape drive is one of several devices connected to the SCSI bus, and it is the last
device connected to the SCSI bus.
5. If either condition exists in step 4 , attach a “Y” adaptor cable to the tape 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.
N OTE : You must supply the “Y” adaptor cable to connect both the SCSI
connector and the terminator to the tape drive.
6. Attach the power cables to the tape 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 4-13 shows the location of this connector; Table 4-6 on
page 4-16 lists the pin assignments for the loader connector.
