INSERTING/REPLACING THE HARD DRIVES IN THE RAID SYSTEM
Place the RAID System with its front view facing you. Position both hands on the front edge.
Simultaneously, push the lid in the direction away from you, front to back, using your thumbs.
A “click” sound would indicate the release of the top lid security clasp.
Lift the top lid up to remove and expose the top view (or DD slots). Take out the handles from
the enclosure itself and locate the DD screws in the packaging box.

ARCTICR C 2T – 2Bay RAID System - User Manual Page | 12
(Fasten the Handles on HDDS)
Place the DD with the metal cover side facing up and ensure that the interface connectors are
oriented toward your left side.

Finally, conduct a test by sliding the handle to ensure the holes glide smoothly on the screw
guides. Repeat the same procedures for the second DD.
The auto-limiting segmented screws are designed to prevent the DDs and/or the
handles from damage due to over-tightening. Furthermore, this design makes the
handle slide easily.

ARCTICR C 2T – 2Bay RAID System - User Manual Page | 15
To insert the DD, hold the handle when it is in the upward position.
When inserting the DD on its reverse side, the SmartGuiderTM System won’t be able to
align and the DD cannot be inserted.
Align the handle with the guide rails and slide the DD into the indicated slot. Firmly push
downward until a “thump” sound is heard. Repeat the same procedures for the second DD.
In most cases, you would need to firmly push the DDs to close until a “thump”
sound is heard.

C NNECTING THE RAID SYSTEM T A C MPUTER
Complete the following steps to connect the RAID System to a host computer.
The RAID System should only be connected to a host computer via one interface.
Connection of the system to a computer via two or more interfaces simultaneously is
not recommended.
Connect the AC/DC power adapter.
eSATA
DC IN
RAID
Insert both ends of the USB 2.0, eSATA, FireWire 400, or FireWire 800 cable(s) into the
corresponding port of the RAID System and the host. Use only ONE cable.
eSATA

Turn the power switch to the “ON” position.
When connected, the Power LED light will be steady green and the DD LED lights will become
white and blink about 15 seconds. If the DDs are inside the RAID System, the DD LED lights
will remain steadily white. If there are no DDs inside the RAID System, the DD LED lights will
turn OFF after blinking.

You are now ready to begin using your RAID System!
Ready to
GO!
Due to compatibility issues, if you use the eSATA interface to do the data transfer, the
Silicon Image eSATA host controller is highly recommended.
Connecting Multiple Devices
Using FireWire 400 or 800, you can connect other computer hardware or digital devices to your
RAID System. This connection is called “Daisy chain.” Items which may be connected might be
such as digital video camera, another D or DVD writer. owever, you must use the same
interface in order for Daisy Chain to work. The computer will not recognize the different
interfaces if they are all used at the same time. In addition, if a mix of connections is used, the
resulting speed will be limited to the lowest one available.
When only one of the FireWire connectors is plugged in, the other FireWire connector
will be viewed as a “daisy chain” port. When only one of the USB or eSATA connectors
is plugged in, the connector will be viewed as its original port, either USB or eSATA respectively.

RAID M DES
A Redundant Array of Independent (or Inexpensive) Disks (RAID) is a system that utilizes
multiple hard drives to share or replicate data among the disks. The benefit, depending on the
selected RAID Mode (combinations of disks), is one or more of the following: increased data
integrity, fault-tolerance, and throughput or capacity when compared to single drives.
Deleting the current partition prior to changing RAID modes is highly recommended.
Using identical DDs with the same capacity and RPM and from the same
manufacturer is highly recommended for best capacity utilization.
