Hardware Installation
WARNING! Hard drives and storage enclosures require careful handling, especially
when being transported. If you are not careful with your hard disk, lost data may
result. Always handle your hard drive and storage device with caution. Be sure that
you are properly grounded by wearing an anti-static strap when handling computer
components or discharge yourself of any static electricity build-up by touching a large
grounded metal surface (such as the computer case) for several seconds.
1. Install your 3.5” Hard Drives.
a) Using an included Drive Door Key, turn the Drive Lock for your desired drive
door, clockwise to the OPEN position.
b) Pull the Door Latch forward and let the drive door swing outwards to reveal the
drive bay.

c) Gentley slide your desired 3.5” Hard Drive into the drive bay with the label
facing up until you feel resistence, and the drive door begins to close over
the drive.
d) While holding the drive latch open, swing the drive door closed. Once the drive
door is completely closed, release the drive latch.

e) (optional) Using an included Drive Door Key, turn the Drive Lock counter
clockwise to the LOCK position.
Note: If you are installing more than one drive repeat these steps on the remaining
drive door.
2. Using the included power adapter, connect the Power Adapter Port on the
S352BU33RER to an available power outlet.
3. Connect the S352BU33RER to your computer system using the included USB 3.0
cable or the eSATA cable depending on your desired host connection.
4. Set your desired RAID conguration and/or power on the device.
WARNING! In order to prepare your drives for RAID operation, this enclosure will
congure newly installed drives into your desired RAID conguration. Please be
aware that any data currently on the drives may be lost during this process. It is
recommended that you back up all data prior to setting your RAID conguration.
a) Ensure the S352BU33RER is powered o.
b) Adjust the RAID Control Switch to your desired RAID conguration. (See list of
RAID congurations)
c) Press and hold the RAID Mode Button while turning on the S352BU33RER on by
pressing the Power Button.
Note: RAID conguration is only required for initial conguraiton or if you would like to
change your RAID conguration.

Available RAID Congurations
The S352BU33RER enclosure supports 4 dierent RAID congurations. RAID is a
storage technology that combines multiple hard drives into a single unit for secure
data redundancy, increased volume size and/or improved performance.
Descriptions and benets for each available RAID conguration are listed below:
Normal - JBOD
In JBOD, no RAID conguration is set and both drives appear as individual disks.
Note: For both drives to be detected while connected via eSATA the host controller must
support SATA Port Multiplier.
BIG/Spanning – Combine
In BIG, both drives appear together as a larger individual disk the size of both drives
combined. This conguration enables you to create a larger volume than would be
available using a single drive without the performance increase oered with RAID 0.
RAID1 – Mirroring
In RAID1 both drives appear as a single disk and data is written identically to both. This
level protects your data from individual drive failure as a backup of all data is written
instantly.
RAID0 – Striping
In RAID0 both drives appear together as a larger single disk the size of both drives
combined. This level can improve your performance as read and write operations are
performed in parallel on separate disks.
LED Indicators
The hard drive enclosure oers LED indicators for each drive so you can monitor drive
activity and the health of your RAID array. The LED will ash while the hard drive is
being accessed. Do not remove the enclosure from the host computer while the LED is
ashing, as it could damage the drive or the enclosure, resulting in data loss.
