Figure 12. Jumper Configurations

If you need to change any of the factory-default settings, you must first power-cycle
the drive by turning it off and then on again, or a SCSI Bus Reset command must be
received for the new switch settings to take effect.
If the default address setting ID = 0 is correct for your system and you do not want
to change any other options, go to "Mounting the Drive" on page 27.
Otherwise, refer to Figure 9 on page 22 and the appropriate following section, make
the changes and then go to "Mounting the Drive."
The three jumper locations for ID = 0, ID = 1 and ID = 2 correspond to the SCSI
device address identification bits 0 (LSB) through 2 (MSB), respectively.
The default setting is SCSI device address = 0.
Be sure that no other device on the SCSI bus has the same SCSI address.
