Locate the SCSI address push switch. Select the SCSI address for the drive by
pressing the (+) or (–) button until the desired address (0 through 7) appears in the
window.
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.
The external drive provides two SCSI connectors to allow daisy-chain connections.
(See Figure 16.) Either connector can connect to the host computer or to any other
SCSI device in the daisy chain.
Note. Turn off all power before connecting cables and the terminator.
