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.

6 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.
