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 ar
e 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 2-9 for an illustration of cable r
outing 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.
