supplied screws and screw driver.
Press the front door in to release the latch and open the door. The2.

Inside will be a metal drive cage in front of the drive bays. Along3.
the top of the drive cage are two small tabs. Press them down to
release the cage and remove it.

a drive is installed in the bottom slot. This will help when reinstalling
the metal cage. Hard drives can be removed from the enclosure by
pressing down on the handles, then pulling them out.
Once all of the hard drives are installed, reinstall the metal cage5.
and front door. Make sure the bottom of the cage stays inside of the
track before closing the cover.

enclosure and power up the enclosure.

enclosure is natively supported, so the drivers are already installed.

How to Use
eSATA/USB Connectivity
The enclosure features two separate host interfaces, which can be
physically connected at the same time, however only one will be active
at a time. The enclosure could even be connected to two different
computers, one over eSATA and the other over USB, and then switched
between. The eSATA and USB Link LEDs, located above the Power
button, will indicate which interfaces are connected, while the eSATA
and USB Mode LEDs will indicate which interface is currently active.

55oC), or set manually to run constantly at one speed.
