Preparing the Tape Drive
1 Check the tape drive's SCSI ID setting to ensure that it is set to the number you expect.
2 Locate the SCSI ID selector on the back panel of your tape drive (see figure 3.2) and
Figure 3.2 SCSI ID selector on rear panel of tape drive
Note
To prepare the tape drive for installation, you need to make sure that it has the correct
SCSI ID and termination settings. Each SCSI device requires a unique SCSI ID. You
need to change the tape drive's default SCSI ID setting of 4 only if the computer
already has a device with ID 4. See "Planning the SCSI Bus" on page 1-9 for more
information about SCSI IDs and SCSI bus termination.


If you do not need to change the SCSI ID, note the default SCSI ID of 4 on the
inside front cover of this book and then go to step 3.


To change the tape drive's SCSI ID, continue with the next step.
use a pen or small screwdriver to press the buttons on the top or bottom of the SCSI ID
selector until the correct SCSI ID number is displayed.
Both the computer and the tape drive check the SCSI ID only at power-on. If you
change the tape drive's SCSI ID while the system is running, the new SCSI ID will
not take effect until next time the system and the tape drive are powered on.
