Step 3 Connect to an AC electrical outlet that you know is
grounded, and that uses the correct voltage level for
your locale. Supported levels range from 100V
to 240V.
To protect your DMP from electrical surges, we recommend
that you use a surge protector or an uninterruptible power
supply from a reputable manufacturer.

Checking the LEDs
The DMP chassis contains a green LED and a red LED. After
you attach your DMP to its AC power source, you should see
light from both LEDs through the DMP front grille.
The LEDs tell you if your DMP has power and if it has obtained
an IP address.
• A solid green LED indicates that a power source
is available.
• A solid red LED indicates that your DMP is trying to obtain
an IP address. After your DMP has an IP address, it turns
off the red LED.
The LEDs do not blink unless they are exposed to infrared
signal interference.
