D-Link DSM-600 Quick Install Manual page 7

Connect the power adapter to the power
receptor on the back panel. Then plug
the other end of the power adapter into a
wall outlet or power strip. After pressing
the power button, the power LED will
blink as the device is starting. The power
LED will become solid when the device is
ready for use.
Note: When you first power on and access the Web-Interface, the DSM-600
will offer to format your hard drive if it is unformatted. This process may take
several minutes depending on the size of your hard drive. During this process,
the power LED will blink. Do not power the unit off during the formatting process.
Once the power LED is solid, you may then access the web based configuration
of the DSM-600.
