Configurations
2.3.1 AC/DC Power
The stand alone AC power supply, which is attached to the unit, is a wall-type
transformer. It should be plugged into a standard AC wall outlet that offers a
ground line. No power ON switch is provided, as the modem powers up upon plug
in.
The 48VDC power version can be configured as +48VDC or -48VDC by connecting
the earth ground (center connector) to either -V or +V, respectively (see Figure 2-3).
A power ON switch is provided.
