2.2 Connecting and Powering ToughTech Duo
a. Connect the data cable to the corresponding port on ToughTech
Duo.
b. Provide power to the ToughTech Duo. There are two possible
ways to do this.
Option 1: If the FireWire host on your computer is powered,
ToughTech Duo can use FireWire for power (QR Model only).
Option 2: Plug the included AC adapter into the DC jack on the
rear of the ToughTech Duo. Plug the other end into a grounded
electrical outlet.
c. Plug the other end of the data cable to an available port on your
computer Ensure that the green power LED indicator is active.

5. Setting up the RAID
ToughTech Duo offers two options for RAID configuration as well
as single-disk mode. See section 1.3 for details on the available
options. Stop all data transfers before setting or changing RAID
types or rebuilding a degraded array. Failure to do so can result
in the loss of data. To set up or change the RAID type, disconnect
all data cables and reboot ToughTech Duo. After the unit has
initialized, the LCD will display the drives’ mode and status. You
can then reconnect to the computer.

a RAID set.”
b. Press “Enter” on the front interface twice.
c. The LCD screen will display “MAKE A NEW RAID?”
d. Select “YES.”
