Section 2 - Getting Started
Attach the hard drive brackets to the sides of your hard drives with the in-
cluded screws. Ensure the brackets are aligned so that when the hard drive is
inserted, the arrow on the bracket points to the front of the ShareCenter .
Insert up to two 3.5" SATA hard drives into the drive bays.
Note: Make sure to align the drive connector to the SATA connector at the
back edge inside the drive bay of the ShareCenter. Gently push the drive in
until it connects. When a drive is inserted properly, you will feel it "set" into
the connector. Some hard drives that are thin or oddly shaped may need to
be inserted carefully into position. If a drive is not properly set in place, the
hard drive LED will not illuminate after powering on the device.
