5.1 Use POE or external Power Adapter
i33V&i33VF, supports two power supply modes, power supply 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 is useful. 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 which meets the
specifications to ensure the device work properly.
