2.2. 2.5" HDD/SSD Installation

1. Remove the blue clasps from the sides of the drive tray.
2. Place the 2.5" HDD/SSD into the drive tray.
3. Use the provided screws to secure the 2.5" HDD/SSD to the drive tray through the corresponding holes.
4. Slide the loaded drive tray into an available bay in the enclosure until it clicks securely into place.

2.3. Raccordement du boîtier

1. Ensure all hard drives are securely installed in their bays.
2. Connect the power adapter to the enclosure's DC 12V port and then to a power outlet.
3. Connect the USB A/C 3.0 cable from the enclosure's USB 3.0 port to an available USB port on your computer.
4. Turn on the enclosure using the ON/OFF switch located at the rear.

3. Modes de fonctionnement (configuration RAID)

This enclosure supports four RAID modes: Normal, JBOD, RAID 0, and RAID 1. The product consists of two 2-bay RAID units combined into a single 4-bay unit, allowing for independent RAID configurations for HDD 1/2 and HDD 3/4. Note: Designing RAID may result in data loss. Always back up important data before changing RAID modes.

To change RAID modes, use the DIP switches located at the rear of the enclosure. After setting the switches, press and hold the "Reset" button for 5 seconds to apply the new RAID array configuration. For MAC OS, RAID software is not provided.

RAID Mode Settings:

• Mode normal :

  (Switch 1 & 2 are down) Each hard disk functions independently. Data is transferred individually to each drive. This mode offers no performance or redundancy benefits.
• JBOD Mode (Spanning):

  (Switch 1 down & Switch 2 up) Joins both hard drives' capacities to provide a single large volume. There is no performance improvement or data redundancy in this mode.

• RAID 0 Mode (Stripping):

  (Switch 1 up & Switch 2 down) Provides the best performance by combining both drives for read/write operations. Data is striped across both drives, increasing speed but offering no redundancy. If one drive fails, all data is lost.

• RAID 1 Mode (Mirroring):

  (Switch 1 & 2 are up) Provides RAID 1 protection against HDD failure. Data is mirrored across both drives, meaning both drives contain identical data. This offers redundancy but reduces usable capacity by half. If one drive fails, data can be recovered from the other.

Transfert de données :

The enclosure is equipped with a JMS561 chip and a USB 3.0 output interface, supporting data transfer speeds of up to 5Gbps under UASP control. This allows for efficient transfer of large files.

4. Maintenance and Features

Circuit de refroidissement:

The 4-bay hard drive enclosure features an aluminum-alloy construction and a built-in cooling fan to maximize data security by dissipating heat. Note: The fan noise is approximately 40-50 decibels. If you are highly sensitive to noise, this product may not be recommended for quiet environments.

Conception antidérapante :

The enclosure is equipped with silicone anti-skid pads to prevent accidental movement and protect the unit from damage.

Indicateurs LED :

• Bleu: Always on means standby mode.
• Rouge: Flashing means reading and writing data.
• Violet: Indique un problème de disque dur.

5. Dépannage et compatibilité

Compatibilité:

The CENMATE 4-Bay RAID Enclosure is plug-and-play compatible with Windows 7 and above, Mac OS 9.1 and above, and Linux operating systems.

Problèmes courants :

• Lecteurs non reconnus : Ensure all drives are properly seated in their bays. Verify the USB cable is securely connected to both the enclosure and the computer. Check the power adapter connection. If changing RAID modes, ensure you have pressed and held the "Reset" button for 5 seconds after setting the DIP switches.
• Data Loss After RAID Change: As noted, changing RAID modes can lead to data loss. Always back up your data before reconfiguring RAID.
• Bruit du ventilateur: The built-in fan operates at 40-50 decibels. This is normal operation. If the noise is excessive or unusual, ensure the enclosure is placed on a stable surface and that the fan vents are not obstructed.
• Vitesses de transfert lentes : Ensure you are using a USB 3.0 port on your computer for optimal speeds. Older USB 2.0 ports will result in significantly slower transfers.
