2. What's in the Box

• D5-310 device x 1
• Power adapter x 1
• Power cord x 1
• USB Type A to C cable x 1
• A handful of screws x 1 (for 2.5-inch drives)

3. Setup

3.1. Hard Drive Installation

The D5-310 supports up to five 3.5-inch SATA HDDs, 2.5-inch SATA HDDs, and SSDs. The drive bays are designed for tool-free installation for 3.5-inch drives, while 2.5-inch drives require screws.

1. Gently pull the drive tray handle to slide out an empty drive tray.
2. For 3.5-inch HDDs: Place the HDD into the tray. The tray's side clips will secure the drive without screws.
3. For 2.5-inch HDDs/SSDs: Secure the drive to the tray using the provided screws.
4. Slide the loaded drive tray back into the enclosure until it clicks into place.

3.3. RAID Configuration

The D5-310 features hardware RAID, configured using a dedicated knob on the rear panel. Ensure the device is powered off before changing RAID modes.

• RAID 5: Provides data redundancy and improved performance. Requires at least 3 drives.
• RAID 0: Maximizes performance and capacity, but offers no data redundancy. Requires at least 2 drives.
• RAID 1: Mirrors data across two drives for redundancy. Requires 2 drives.
• RAID 10: Combines mirroring and striping for both performance and redundancy. Requires at least 4 drives.
• Single: Each disk operates independently.
• Hot Spare: Supported for RAID 1, 5, or 10 configurations to automatically replace a failed drive.

1. Using a small screwdriver (not included), rotate the RAID knob on the rear panel to select your desired RAID mode.
2. Press the "RESET" button (located near the RAID knob) for 5 seconds to confirm the RAID mode change.
3. Power on the device. The new RAID configuration will be applied.

4. Operation

4.1. Power On/Off

Press the power button on the front panel to turn the D5-310 on. To turn it off, press and hold the power button until the device shuts down.

4.2. Data Transfer

The D5-310 utilizes a USB 3.1 Gen 1 interface, providing data transfer speeds of up to 5Gbps. This allows for rapid file transfers, such as moving a 1GB file in approximately 4 seconds.

4.3. Operating System Compatibility

The D5-310 is fully compatible with Windows, macOS (including the latest versions), and Linux operating systems. No additional drivers are required for basic functionality.

5. Maintenance

• Smart Sleep Mode: The device features a hard drive sleep mode to conserve energy and extend drive lifespan when idle.
• Intelligent Cooling System: Temperature-controlled fans dynamically adjust their speed based on HDD temperature to maintain optimal operating conditions. Ensure fan vents are clear of obstructions.
• Power-On Recovery: The D5-310 is designed to automatically restart after a power failure, ensuring continuous operation.
• RAID Failure Alarm: A built-in buzzer will alert you in case of a disk failure within a RAID array.

6. Troubleshooting

• Device Not Recognized: Ensure all cables (power and USB) are securely connected. Try a different USB port or cable. Verify the device is powered on.
• Drives Not Appearing: After initial setup or changing RAID modes, drives may need to be initialized and formatted through your operating system's disk management utility.
• Slow Transfer Speeds: Ensure you are using a USB 3.1 Gen 1 compatible port on your computer. Check the health of your hard drives.
• RAID Array Issues: If a drive fails in a redundant RAID configuration (RAID 1, 5, 10), the D5-310's hot spare feature (if configured) will automatically begin rebuilding. If no hot spare is present, replace the failed drive and initiate a manual rebuild according to the advanced user guide (available on the TERRAMASTER website).
• Unexpected Shutdowns: Ensure adequate ventilation around the enclosure. Check power connections.
