PRECAUTIONS FOR THE RAID SYSTEM
The main circuit board of the RAID System is susceptible to static
electricity. Proper grounding is required to prevent electrical damage to
the RAID System unit or other connected devices, including the host
computer. Always place the RAID System unit on a smooth surface and
avoid all dramatic movement, vibration and percussion.
Do NOT allow water to enter the RAID System unit.
Installation of additional equipment in the host computer may be required.
Visit our website to download the latest product information updates.
Do NOT attempt to service this unit yourself. Disassembling the RAID
System unit’s inner parts will expose you to dangerous voltages or other
hazards.
Do NOT block the ventilation. Proper airflow is required to ensure reliable
operation and to prevent overheating.
Do unplug the RAID System unit from the electrical outlet when not in use
to provide an ecological friendly environment.
Use only the power supply cable provided with the RAID System unit.

INTRODUCTION
Thank you for purchasing the DM4 3.5” SATA HDD 4-bay RAID System. The
DM4 3.5” SATA HDD 4-bay RAID System provides massive storage capacity
and advanced RAID configuration options in a desktop storage device. The
RAID Mode Switch allows easy configuration of RAID 0 (Striping), RAID 1
(Mirroring), RAID 5, RAID 5+HotSpare, and RAID 0+1 RAID modes.
Please thoroughly read and follow the instructions provided in this manual.
Failure to do so may result in damage to the RAID System, and any or all of the
connected devices.
Features
Supports current SATA II compliant HDDs, fully backward compatible with
SATA 1.0 and SATA 1.0a compliant HDDs
Connects flexibly via an eSATA, USB 2.0, 1394a or 1394b port
Provides RAID 0 (Striping), RAID 1 (Mirroring), RAID 5, RAID 5+HotSpare,
and RAID 0+1 for effective storage management
Supports automatic rebuild in RAID 1, RAID 5, RAID 5+HotSpare, and RAID
0+1
Configures RAID modes easily using switches, no IT expertise required
Simplifies RAID management, no software installation required
Monitors system status via LED indicators
Prevents over-tightened HDDs with auto-limiting segmented screws
Features a trayless function with the SmartGuiderand user-friendly design
enables effortless HDD hot-swapping
Dissipates heat efficiently with aluminum housing
Maximizes airflow with silent fans and mechanical designs
Supports hot-plug and HDD hot-swap
Supports both online and offline rebuild
Any loss, corruption, or destruction of data is the sole responsibility of the
user of the RAID System. Under no circumstances will the manufacturer be held
liable for the recovery or restoration of any data.
SmartGuideris a trayless device that utilizes the simplicity of a handle and
screws. The integrated handle is attached to the HDD with auto-limiting
segmented screws. Then, the entire setup can be slide into the unit by aligning
the screws with the specially designed guides. This enables flexibility in removal
and insertion of the HDDs with ease.

INSERTING/REPLACING THE HARD DRIVES IN
THE RAID SYSTEM
1. Place the RAID System with its front view facing you. Position one hand on
the front edge and one on the back edge of the top lid. 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.
2. Lift the top lid up to remove and expose the top view (or HDD slots). Take out
the handles from the enclosure itself and locate the HDD screws in the
packaging box.
