Step 2. Set the SCSI ID
You can set the SCSI ID in one of two ways:
v By placing jumpers on the SCSI ID connector
v
By using a remote SCSI ID switch that is connected to the SCSI ID connector
The sections that follow describe each method of setting the SCSI ID.
Setting the SCSI ID with jumpers
You can set the SCSI ID on the LTO-2 by installing 2-mm jumpers on the drive’s
SCSI ID connector (see
3
in Figure 1 on page 7). Your tape drive may come set to
a default SCSI configuration, with jumpers already installed. You can change the
SCSI ID by rearranging, adding, or removing jumpers.
To set the SCSI ID:
__ 1. Locate the SCSI ID connector (see
3
in Figure 1 on page 7).
__ 2. Before attaching the SCSI bus cable to the server, decide the SCSI ID number
that you want. Make sure that the ID is not being used by another device.
__ 3. Referring to Figure 2, find the ID number that you chose then place jumpers
on the connector pins as shown (use a pair of needle-nose pliers to connect
the jumpers to the pins that are shaded).
Note: Do not set the SCSI ID to 15. This is reserved for applications where
the drive expects to receive the SCSI ID through a command over its
LDI interface.
Setting the SCSI ID with a SCSI ID switch
For applications that use a SCSI ID switch (like an external enclosure), connect the
switch to the drive’s SCSI ID connector (see
3
in Figure 1 on page 7). If any
jumpers are pre-installed, be sure to remove them before connecting the switch.
The SCSI ID switch must be compatible with the drive’s SCSI ID connector and
must make an electrical connection between the same pins as the jumpers to
achieve the same corresponding SCSI ID.
