SCSI termination: The drive is shipped with SCSI
termination disabled. This setting is appropriate if the drive is
attached in the middle of a SCSI chain with other SCSI
devices. If the autoloader is the only device or the last device
on a SCSI chain, you must install a jumper on these two pins.
Terminator power: The jumper pins closest to the power
connector are used to enable +5-volt terminator power if
needed for terminators or other SCSI devices. The factory
default setting (termination power disabled) is appropriate for
most systems. If you need to enable terminator power, place
a jumper firmly over both pins.
Remote SCSI addressing: Six of the pins on the back of the
drive are used for remote SCSI address selection (for
example, if the autoloader is mounted in an external
housing). The table below indicates where jumpers should be
placed to configure the drive for different SCSI IDs.

Note. A terminator power fuse is located beside the
terminator power jumper. The terminator power fuse is
designed to prevent damage to Autoloader components
in case terminator power is shorted. For example, If
terminator power is enabled and the SCSI cable is
connected upside down, this fuse will blow to prevent
damage to the Autoloader itself. If this occurs, return the
Autoloader to an authorized repair facility.

Note. If you use these jumpers for remote SCSI ID
selection, all three of the SCSI ID dip switches on the top
of the drive must be set to OFF .
