3 Installation
3.1 Use PoE or External Power Adapter
X3G
, called as ‘the device’ hereafter, supports two power supply modes, power supply from external
power adapter and X3G supports 802.3af Class 2 Power over Ethernet (PoE) complied switch
PoE power supply saves the space and cost of providing the device additional power outlet. With a
PoE switch, the device can be powered through a single Ethernet cable which is also used for data
transmission. By attaching UPS system to PoE switch, the device can keep working at power outage
just like traditional PSTN telephone which is powered by the telephone line.
For users who do not have PoE equipment, the traditional power adaptor should be used. If the
device is connected to a PoE switch and power adapter at the same time, the power adapter will be
used in priority and will switch to PoE power supply at power failure on the power adapter.
Please use the power adapter supplied and the PoE switch met the specifications to ensure the
device worked properly.
