Setting the SCSI ID with a SCSI ID Switch
If your enclosure uses a SCSI ID switch (rather than jumpers), connect the switch
to the drives SCSI ID connector (see 3 in Figure 2 on page 14). If any jumpers
are pre-installed, be sure to remove them before connecting the switch. The SCSI
ID switch must be compatible with the drives SCSI ID connector and must make an
electrical connection between the same pins as the jumpers to achieve the same
corresponding SCSI ID.
Setting the SCSI ID Through the LDI Interface
If you are installing the Ultrium 2 Tape Drive into a tape library, you can issue a
command from the library to set the drives SCSI ID through the LDI interface.
Make sure that the SCSI ID is set to 15 (see Figure 5). When configured to accept
its SCSI ID through the LDI interface, the drive does not respond to SCSI
commands until it receives a Set Configuration command through the interface.
Supplying TERMPOWER (SCSI Drive Only)
To supply TERMPOWER to the bus, locate one of the five jumpers shipped with the
Ultrium 2 Tape Drive and place it on the SCSI ID connector as shown in the
following figure. Place the jumper on the pins that are shaded.

Note that you must provide SCSI termination externally to the Ultrium 2 Tape Drive.
