Setup
1. Hardware Installation
Follow these steps to install your hard drives into the enclosure:
- Unpack the enclosure and gently pull out the internal hard disk card slot/tray.
- Align your 2.5-inch or 3.5-inch SATA HDD/SSD with the interface on the tray and firmly install it. Secure the drive with the provided screws.
- Before inserting the tray back, adjust the DIP switches on the unit to select your desired RAID mode. The factory default setting is JBOD mode. (Refer to the 'RAID Mode Configuration' section for details on modes).
- Insert the installed hard disk tray back into the enclosure until it clicks into place.
2. Connecting to Power and Computer
- Connect the 12V/4A power adapter to the DC 12V port on the back of the enclosure and plug it into a power outlet.
- Connect one end of the USB-C data cable to the USB-C port on the enclosure and the other end to an available USB port on your computer or compatible device.
Operating Instructions
1. Power On/Off
Press the 'POWER' button on the back of the enclosure to turn it on or off. The indicator lights on the top will illuminate when the device is powered on and drives are active.
2. RAID Mode Configuration
WARNING: Always back up your data before changing RAID modes. Changing RAID modes will erase all data on the drives.
The enclosure supports four RAID modes, which are configured using DIP switches on the back of the hard disk tray. The factory default is JBOD mode.
- RAID 0 (Striping): The recognized capacity is twice the capacity of the smaller hard drive. Both switches are turned to the digital position (e.g., 'ON' for both). Note: If any hard disk fails, all data will be lost.
- RAID 1 (Mirroring): Only recognizes the data stored in one hard disk and backs it up to another hard disk at the same time. Set switch No. 1 to the digital position and switch No. 2 to 'ON'. Note: If any hard disk fails, the data will not be lost.
- JBOD (Just a Bunch Of Disks): Recognized as two separate hard disks. Both switches are set to 'ON'. This is the factory default setting.
- SPAN (Concatenation): Recognized as a single large hard disk, where the size is the sum of the two hard disks. Dial switch 1 to 'ON' and dial switch 2 to numbers (e.g., 'OFF').
3. Intelligent Sleep Mode
The enclosure features an intelligent sleep mode that activates automatically after 10 minutes of inactivity to save power and extend drive lifespan. To disable this feature, please contact Acasis customer service for assistance.
4. Data Transfer
The USB-C interface supports 5Gbps high-speed data transfer, allowing for quick file transfers. Measured speeds can reach up to 400MB/s for 1GB file transfers in approximately 3 seconds.
5. Device Compatibility
The Acasis EC-7352 is designed for plug-and-play operation with various devices without requiring additional drivers. It is compatible with:
- Personal Computers (PC)
- Televisions (TV)
- Gaming Consoles (PS4/PS5)
- Routers
Maintenance
1. Cleaning
To clean the enclosure, use a soft, dry, anti-static cloth. Do not use liquid cleaners or solvents, as they may damage the finish or internal components.
2. Cooling
The enclosure features a built-in silent fan and an aluminum body for efficient heat dissipation. Ensure that the ventilation grilles are not obstructed to maintain optimal cooling performance and prevent overheating of the hard drives.
3. Data Protection
The device incorporates multiple protection features for storage safety, including overcurrent, overheat, voltage isolation, and short circuit protection.
Troubleshooting
- Device not recognized by computer:
- Ensure all cables (power and USB-C) are securely connected.
- Verify the enclosure is powered on.
- Check if the hard drives are properly installed and seated in their trays.
- Confirm the RAID mode DIP switches are set correctly for your intended use. Incorrect RAID settings can prevent recognition or cause data issues.
- Try connecting to a different USB port or computer to rule out port/system issues.
- For new drives, ensure they are initialized and formatted in your operating system's Disk Management (Windows) or Disk Utility (Mac).
- Data loss or corruption after RAID configuration:
- Changing RAID modes will erase all data. Always back up your data before making any changes to RAID settings.
- If data was lost due to a RAID change without backup, data recovery may be difficult or impossible.
- Only one drive recognized in a dual-bay setup:
- In JBOD mode, both drives should appear as separate volumes. If only one appears, check the installation of the second drive and the DIP switch settings.
- Ensure both drives are healthy and properly formatted.
- Enclosure goes to sleep too quickly/doesn't wake up:
- The intelligent sleep mode activates after 10 minutes of inactivity. Accessing the drive should wake it up.
- If you wish to disable the sleep mode, please contact Acasis customer service for specific instructions.
User Tips
- The Acasis EC-7352 is constructed from high-quality aluminum, contributing to its durability and heat dissipation.
- This dual-bay enclosure is versatile, supporting both 2.5-inch and 3.5-inch SATA HDDs/SSDs, making it suitable for various drive types you might already own.
- While the enclosure supports up to 48TB total capacity, it can also function effectively with just a single HDD installed if you don't need both bays immediately.
