Installation

2.3 Installation

The SiP VoIP and PoE Speaker is a tabletop unit with mounting feet that sit on a flat surface.

2.4 Connections

This following topics provide illustrations and information on connecting the SiP VoIP and PoE Speaker to power supplies, the host, and peripheral devices.

2.4.1 Power Supply

The PoweredUSB specification requires supplying +12V at 1.5A to each voltage designated port. These requirements are met only if the power supply has sufficient wattage for this amount of power.

The Epson PS180 brick and Dell printer power supply are examples of lower-cost alternate power supplies that can be used with this Hub and peripherals requiring less power. Two power plug receptacles are provided on the back of the SiP VoIP and PoE Speaker to facilitate the use of alternate power supplies.

The three-pin connector is normally used for the Dell and Epson Bricks. The four-pin connector is used for a high-current power supply. See Figure 2-9for an illustration of cable routing from the SiP VoIP and PoE Speaker.

CAUTION The P1 and P2 DC input jacks on the back of this Hub are for input only. Do not plug power supplies into both input jacks simultaneously as equipment damage that might void the product warranty could occur.
