How to Use
1. Open the front cover of the M.2 SSD, the M.2 M-Key socket is visible,
insert the M.2 hard disk and insert the fixing rubber plug.
2. For 3.5/2.5" HDD installation, just insert it directly into the docking
station. When using 3.5" HDD, you must connect a DC12V power supply.
In general, the power adapter is not necessary when using a 2.5"
SSD/HDD (if the USB Host power supply is insufficient, you need to
connect a DC power supply).
