User Manual for OWC Mercury Elite Pro Dual 3-Port Hub

Quick Guide

The OWC Mercury Elite Pro Dual 3-Port Hub is a high-performance storage enclosure. To get started, ensure your computer meets the system requirements, install your SATA drives, configure the desired RAID mode using the rear dial, and connect the device to your computer via the USB-C host port. Always unmount drives properly before disconnecting to prevent data loss.

System Requirements

• Operating System: Mac, Windows 7 or later, Linux, iPadOS 13+, Android 10+, ChromeOS.
• Hardware: Any computer, tablet, or phone with a USB or Thunderbolt (USB-C) port.
• Supported Drives: 3.5" or 2.5" SATA HDDs/SSDs.

Front and Rear View

Front Panel: Features Drive A and Drive B status LEDs (blink green for activity, red for errors) and a Power LED (solid white for power, solid blue for active system connection).

Rear Panel: Includes the RAID selector dial, RAID Set button, USB 3.2 Gen 2 Type-C Host Port, USB 3.2 Gen 2 Type-C Hub port, USB 3.2 Gen 2 Type-A Hub ports, Kensington Security slot, and DC IN power port.

Assembly

1. Place the device on a static-free surface.
2. Remove the two screws from the back of the enclosure and slide out the inner chassis.
3. Place your SATA drive(s) into the housing with the label facing upwards.
4. Affix the drive to the inner chassis using the appropriate screw holes (red circles for 3.5" drives, yellow circle for 2.5" drives).
5. Slide the chassis back into the enclosure and secure it with the screws removed in step 1.

Hardware RAID Configuration

The device supports RAID 0, RAID 1, Span, and Independent modes. Note: Changing the RAID mode will result in data loss if drives contain data.

1. Connect the device to power and your computer.
2. Use a paper-clip or flat-head screwdriver to rotate the RAID dial to the desired mode.
3. Press and hold the RAID Set button for 3-5 seconds until the new volume(s) appear on your computer.
4. Format the new volume(s) using your operating system's disk management tools.

Device Management

• Drive Failure: If a drive fails, the corresponding LED will light up solid red.
• Replacing Drives: In RAID 1, a failed drive can be replaced to rebuild the array. In RAID 0, Span, or Independent modes, data on the failed drive is lost.
• Unmounting: Always eject or unmount the disk(s) from your OS before powering off or disconnecting the device to ensure data integrity.

Troubleshooting

• If the device does not power on, verify the power cable connection and ensure the power strip is switched on.
• If a drive LED is solid red, the drive may have failed, be missing, or not be connected properly.
• If RAID mode changes are not working, ensure the drives are mounted; unmounting them puts them in a powered-down state that prevents configuration changes.
