5.1 PoE and the use of external power adapters

H2P telephones support two power supply modes, from an external power adapter or a Power-over-Ethernet
(PoE) compliant switch. The H2 telephone does not support PoE function.
The PoE power supply saves the space and cost of providing the device with an 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 a UPS system to the PoE switch, the device can keep working during power
outages just like a 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 as the
priority source, and the device will switch to the PoE power supply once the power adaptor source fails.
Use standard power adapters and a PoE switch conforming to specifications to ensure the proper operation
of the equipment.
