Disconnect Button
The Disconnect button is located on the back panel of the DNS-120. This button will
safely disconnect all attached USB drives on the DNS-120.
To safely remove a USB drive from the DNS-120, press the Disconnect button on the
back panel until the USB LED blinks red. After the USB LED turns off, it is safe to
remove all USB drives from the DNS-120.
Note: If a USB drive remains attached to the DNS-120 after being disconnected, it will
no longer be accessible. That USB drive must be reconnected in order to be available
for access again.
To ensure that risk of data loss is minimized, it is important to make sure that no
users are currently accessing files on the DNS-120 while disconnecting USB drives is
in progress.

and release. The Ethernet LED will turn off momentarily, and then light green.
Wait approximately 30 seconds for the DNS-120 to complete the reset cycle before you
begin using it again.
