5.1 Use POE or external Power Adapter
i12 supports two power supply methods, external power adapter and Ethernet (POE) switch power
supply mechanism
The POE power supply mode saves space and the cost of additional power sockets. i12 is connected
to the POE switch through a network cable to play the role of power supply and data transmission. By
connecting to the POE switch of the UPS system, the i12 can continue to work even if the power is cut
off, just like a traditional PSTN phone powered by a telephone line.
Users who do not have POE equipment can also use traditional power adapters. If the i12 is
connected to the POE switch and the power adapter at the same time, the POE power supply is
preferred. If the POE power supply fails, it will be switched to the power adapter.
In order to ensure the normal operation of the equipment, please use the power adapter specified by
Fanvil and the POE switch that meets the equipment standard.
