5. Setup and Installation

5.1. SSD Installation

1. Gently slide open the enclosure cover to reveal the SSD slots.
2. Insert your M.2 NVMe SSDs (up to two) into the designated slots (SSD1 and SSD2). Ensure the SSDs are M-Key and compatible with 2230/2242/2260/2280mm sizes.
3. Secure the SSDs using the provided rubber plugs.
4. Apply the silicone and aluminum thermal pads to the SSDs and chipset as indicated in the diagram for optimal heat dissipation.
5. Carefully close the enclosure cover.

5.2. RAID Mode Configuration

The enclosure supports four RAID modes: RAID 0, RAID 1, PM, and JBOD. You can select the desired mode using the DIP switches located inside the enclosure. Always back up your data before changing RAID modes, as this process will erase all data on the SSDs.

1. With the enclosure disconnected from power and your computer, open the enclosure cover.
2. Locate the DIP switches (labeled 1 and 2) near the SSD slots.
3. Set the DIP switches according to the desired RAID mode as shown in the diagram below:
• RAID 0 (Striping): Switches 1 and 2 set to ON (Left ↑ Right ↑). Offers maximum speed and combined capacity, but no data redundancy.
• RAID 1 (Mirroring): Switch 1 ON, Switch 2 OFF (Left ↑ Right ↓). Provides data redundancy by mirroring data across both SSDs, capacity is limited to the smaller SSD.
• JBOD/LARGE: Switch 1 OFF, Switch 2 ON (Left ↓ Right ↑). Combines the capacity of both SSDs into a single logical volume without striping or mirroring.
• PM/NORMAL: Switches 1 and 2 set to OFF (Left ↓ Right ↓). Treats each SSD as an independent drive.
4. Close the enclosure cover.
5. Connect the power adapter to the enclosure.
6. To activate the new RAID mode: With the device turned off, press and hold the Reset button. While holding Reset, press the Power button once. Continue to hold the Reset button for approximately 3-5 seconds until the corresponding RAID indicator light illuminates. Then release the Reset button.
7. Connect the enclosure to your computer using the provided USB-C cable.
8. Initialize and format the new volume through your operating system's disk management utility.

6. Operating Instructions

6.1. Connecting to Your Device

1. Ensure the enclosure is powered on via the independent 5V 3A power adapter.
2. Connect the enclosure to your computer or compatible device using the appropriate USB-C to USB-C (20Gbps) or USB-A to USB-C (10Gbps) data cable.
3. The enclosure is plug-and-play; your operating system should automatically detect the device.

6.2. LED Indicator Status

The front panel features LED indicators to show the working status:

• Power LED: Indicates power status.
• SSD1/SSD2 LEDs:
• White (Solid): SSD is in standby mode.
• White (Flashing): SSD is actively reading or writing data.
• Red: Indicates a hard drive failure (e.g., in RAID 1 if one drive fails).
• RAID Mode Indicator (Blue LED): Illuminates to confirm the selected RAID mode after configuration.

6.3. Hot Swapping

The enclosure supports hot-swapping of SSDs in PM (Normal) or JBOD modes, allowing you to insert or remove drives without powering down the enclosure or your computer. For RAID 0 and RAID 1, it is recommended to power down the enclosure before making any changes to the SSDs.

7. Maintenance

• Cleaning: Use a soft, dry cloth to clean the exterior of the enclosure. Avoid using liquid cleaners or solvents.
• Heat Management: NVMe SSDs can generate significant heat, especially during intensive operations. While the enclosure is designed for excellent heat dissipation, ensure it is placed in a well-ventilated area. If prolonged high temperatures are observed, consider using external cooling solutions like a USB fan.
• Cable Management: Ensure all cables are securely connected and not under strain.
• Firmware Updates: Periodically check the MAIWO official website for any available firmware updates for your enclosure model to ensure optimal performance and compatibility.

8. Troubleshooting

• Enclosure not detected by computer:
  • Ensure the power adapter is securely connected and the enclosure is powered on.
  • Try a different USB port on your computer.
  • Test with a different USB data cable.
  • Verify that the SSDs are correctly seated in their slots.
• RAID mode not setting correctly:
  • Ensure the enclosure is powered off before setting the DIP switches.
  • Follow the RAID mode configuration steps precisely, especially the reset procedure (hold Reset, press Power, continue holding Reset for 3-5 seconds).
  • Confirm the DIP switches are firmly in the correct ON/OFF positions for your desired mode.
  • If issues persist, contact MAIWO customer service for assistance.
• Slow transfer speeds:
  • Ensure you are using the 20Gbps USB-C to USB-C cable and connecting to a compatible USB 3.2 Gen2x2 port on your computer.
  • Verify that your SSDs are high-performance NVMe drives.
  • Monitor the enclosure's temperature; excessive heat can lead to thermal throttling and reduced performance. Ensure adequate ventilation.
  • Check your computer's drivers for USB controllers.
• SSD LED shows red:
  • A red LED typically indicates a drive failure, especially in RAID 1. If this occurs, the enclosure may attempt to rebuild the array if a new drive is inserted.
  • If you are in RAID 1 and one drive shows red, you can often still access data from the healthy drive. Replace the faulty drive and allow the array to rebuild.
