with your drives, you may lose data as a result. Make sure
that you’re properly grounded when handling a Drive or
Adapter.

Installation Holes that match the height of the Drive. If the
Standos and Installation Screws are already installed in
the correct position, proceed to step 6.

in place while using a Phillips Head Screwdriver to remove
the Screw on the back of the Adapter. Then use the Phillips
Head Screwdriver to remove the Screw on the front of the
Adapter.

corresponding M.2 Connector on the Adapter and press
the Drive down toward the adapter until the Drive is in
place.
Note: The M.2 Connector on the Drive is keyed so that it

matches the length of your drive.
7. Replace the Stando Installation Screw that you removed
in step 2 and tighten it in place.
8. Insert the Drive Mount Screw through the Drive Slot and
into the Stando. Use the Phillips Head Screwdriver to
tighten the Drive Mount Screw, securing the Drive in place.
9. Repeat Steps 5 - 7 to install the second Drive into the
Adapter.
Installing the Low-Prole Bracket
The Adapter can be mounted in both low-prole and full-
prole computer systems. By default, the full-prole bracket
comes pre-installed in the Adapter.

Screws from the Adapter.
2. Remove the Full-Prole Bracket from the Adapter.
3. Align the Screw Holes on the Low-Prole Bracket with the
