Install a drive
Warning! Drives should be handled carefully, especially when they’re transported.
If you’re not careful with your drives, you may lose data as a result. Always handle
storage devices with caution. Make sure that you’re properly grounded by wearing an
anti-static strap when you install any computer component. If an anti-static strap isn’t
available, touch a large, grounded metal surface for several seconds to discharge any
built-up static electricity.
1. Use a Phillips screwdriver to remove the four screws in the back panel of the dualbay enclosure.
Note: If you’re using the dual-bay enclosure for the rst time, you don’t need to remove
any screws because the dual-bay enclosure ships without the screws installed.
2. Slide the back panel away from the dual-bay enclosure to reveal the drive tray.
3. Place the drive tray on its side with the green Set RAID button facing upwards.
4. Gently slide a 3.5 in. HDD, SSD, or SSHD into one of the drive trays so that the SATA
connector on the drive lines up with the corresponding connector on the drive
tray. The connector on your drive is keyed so that it only ts in the drive tray one
way.
5. To secure the drive in place, use a Phillips screwdriver to insert two of the provided
screws into each side of the drive tray the drive is in, and tighten the screws in
place.
6. To install a second drive, repeat steps 4 and 5.
7. Set a RAID mode. For more information about how to do this, see the “Set a RAID
mode” section.
8. Slide the drive tray back into the dual-bay enclosure.
9. Use a Phillips screwdriver to insert the four screws into the back panel, and tighten
the screws in place.
10. Connect the universal power adapter to the Power adapter port on the dual-bay
enclosure and a power outlet.
11. Connect one of the provided USB cables to the USB 3.1 port on the dual-bay
enclosure and a USB port on your computer.
