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 sup12V 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
for 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.
