5.1 Use POE or external Power Adapter
PA2S called as ‘the device’ hereafter, 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 should be used. If the
device is connected to both POE switch and external power adapter, PA2S will get power
supply from POE switch in priority, and change to external power adapter once the POE power
supply fails.
Please use the power adapter and the POE switch met the specifications to ensure the device
work properly.
