1. Insert the hard drives into the bays.
2. Connect the appropriate data cable (USB A/C 3.0 or eSATA) from the enclosure to your computer.
3. Connect the power adapter to the enclosure and plug it into a power outlet.
4. Turn on the enclosure. It is plug-and-play compatible with Windows 7 and above, Mac 9.1 and above, and Linux operating systems.

6. Operating

6.1. RAID Modes Configuration

The enclosure supports 8 RAID modes: RAID 0, 1, 3, 5, 10, CLONE, LARGE, and NORMAL. These modes are configured using DIP switches located on the device.

Figure 6.1: Visual guide for setting the 8 RAID modes using the DIP switches (1-4) on the enclosure.

Figure 6.2: Overview of the 8 RAID modes, showing the corresponding DIP switch settings for each mode.

Important: When changing RAID modes, you must first return the setting to NORMAL mode. Changing RAID modes may result in data loss. MAC OS does not support RAID software for this device.

RAID Mode Setting Procedure:

1. Ensure the USB cable is connected to your computer.
2. Power off the enclosure.
3. Set the DIP switches to NORMAL mode (all switches down).
4. Hold the reset button (located near the DIP switches) BEFORE you flick the ON switch. Continue holding the reset button for approximately 10 seconds after turning the power on.
5. Power off the enclosure again.
6. Set the DIP switches to your desired RAID mode according to the diagrams above.
7. Repeat steps 1 to 4 to apply the new RAID configuration.

6.2. Data Transfer

The enclosure supports data transfer speeds of up to 6Gbps, facilitated by the JMS567+JMB393 chip and USB 3.0/eSATA interfaces under UASP control.

7. Maintenance

To ensure the longevity and optimal performance of your CENMATE enclosure:

• Keep the device clean and free from dust. Use a soft, dry cloth for cleaning.
• Ensure adequate ventilation around the enclosure. Do not place it in enclosed spaces that could restrict airflow.
• The built-in fan helps maintain optimal operating temperatures. Ensure the fan is not obstructed.
• The fan noise is typically around 40-50 decibels. This is normal operation.

8. Troubleshooting

• Device Disappears Randomly: Ensure the USB cable is securely connected and the power supply is stable. Try connecting to a different USB port or using a different cable. Restarting the unit may temporarily resolve the issue.
• Fan Not Working: The fan requires a USB or eSATA cable to be connected to function. Ensure a data cable is properly connected to your computer.
• Hard Drive Not Recognized / Purple LED: Check if the hard drive is properly seated in its bay. Ensure the tray protrusions do not conflict with the hard drive; if they do, follow the instructions in Section 5.1 to modify the tray or use screws for installation. Try the hard drive in a different bay or test it directly with a computer if possible.
• Data Loss After RAID Configuration: Always back up your data before changing RAID modes. When replacing RAID, you must return to NORMAL mode first and then set the desired RAID mode, following the specific procedure outlined in Section 6.1.
• Slow Data Transfer: Ensure you are using a USB 3.0 or eSATA port on your computer. Verify that the cables are not damaged.
