4. Setup and Installation
4.1. 3.5-inch Hard Drive Installation
- Pull the blue latch on both sides of the tray.
- Gently place the 3.5-inch hard drive into the tray, aligning the pins with the side holes.

Figure 4.1: Installation steps for a 3.5-inch HDD.
4.2. 2.5-inch Hard Drive/SSD Installation
- Remove the blue latch on the side using a screwdriver.
- Use the provided screws to secure the 2.5-inch HDD/SSD into the corresponding holes in the tray.

5. Operating Instructions
5.1. Connecting to Your Computer
- Ensure all drives are securely installed in their respective bays.
- Connect the power adapter to the enclosure and plug it into a power outlet.
- Use the provided USB-A or USB-C cable to connect the enclosure to your computer's USB port.
- Turn on the main power switch located on the rear panel of the enclosure.
- The enclosure is plug-and-play. Your operating system should detect the drives automatically. You may need to initialize and format new drives through your operating system's disk management utility before use.
5.2. Compatibility
The CENMATE enclosure is compatible with:
- Operating Systems: Windows 7 and above, Mac OS 9.1 and above, Linux, Chrome OS.
- Interfaces: USB 3.0, USB 3.1, USB 3.2, Thunderbolt 3, Thunderbolt 4.

6. Maintenance
6.1. Cooling Fan
The enclosure features a built-in 2-inch cooling fan designed to continuously cool the drives and protect data security. The fan operates at approximately 40-50 decibels. If you are sensitive to noise, this product may not be ideal for quiet environments. Sleep mode installation files are available to adjust the product's sleep duration according to your needs, which can help manage fan noise during idle periods.

6.2. General Care
- Keep the enclosure in a clean, dry environment, away from direct sunlight and extreme temperatures.
- Avoid blocking the ventilation openings to ensure proper airflow for the cooling fan.
- Clean the exterior with a soft, dry cloth. Do not use liquid cleaners or solvents.
7. Troubleshooting
7.1. LED Indicators
The front panel features LED indicators for each drive bay to help monitor status:
- M.2-1 (Violet LED): Solid blue when connected, blinks for read/write activity.
- M.2-2 (Red LED): Solid red when connected, blinks for read/write activity.
- M.2-3 (Red LED): Solid red when connected, blinks for read/write activity.
- HDD1 (Blue LED): Solid blue when connected.
- HDD2 (Blue LED): Solid blue when connected.

7.2. Common Issues
- Drives Not Detected:
- Ensure all cables (USB and power) are securely connected.
- Verify that the main power switch on the enclosure is turned on.
- Check if new drives are initialized and formatted in your operating system's disk management utility.
- Confirm M.2 SSD compatibility (NVMe M-Key or M&B-Key only, not SATA B-Key).
- Slow Data Transfer Speeds:
- Ensure you are connected to a USB 3.2 Gen 2 (10Gbps) port on your computer. Older USB ports will result in lower speeds.
- Verify the quality of the USB cable. Use the provided cables or certified USB 3.2 Gen 2 cables.
- Actual speeds are limited by the slowest component (drive, cable, port). M.2 SSDs may not reach their maximum theoretical speeds if the enclosure's controller or host interface is a bottleneck.
- Fan Noise:
- The fan operates continuously for cooling and may produce audible noise (40-50 dB).
- Consider using the provided sleep mode installation files to configure the enclosure to enter sleep mode during idle periods, which can reduce noise.
