5.1 PoE and the use of external power adapters
The devices support two power supply modes from external power adapter or 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 once it fails.
Please use the power adapter supplied by Fanvil and the PoE switch met the specifications to ensure the
device to work properly.
