[ENG] [Input+Relay 254R304] 8. PoE Technology

NetPing Input+Relay 254R304 device has two ports ETH1 and ETH2.
ETH1 (PoE IN) port is located on the front panel of the device and used to supply power to the device using a PoE
injector or other PSE device. You can switch on the power of the devide inselvf from PoE via the web-interface
(switched off by default).
It is forbidden to power the device from both 12V adapter and PoE simultaneously.
The supply voltage range for the ETH1 port is 12–50 V. The ETH1 port is equipped wth a scheme of compliance
determination with PoE devices of af/at standards. The class of power is determined with the switch
IEEE 802.3af (PD 13W) and a class 4 for IEEE 802.3at (PD 25.5W).
You can connect an external 12V power supply to the device.
It is forbidden to power the device from both 12V adapter and PoE simultaneously.
PoE is transmitted in through-connection from the ETH1 entry port to ETH2. PoE through-connection to an output
port can also be switched on or off via the device's web interface (switched off by default). The power supply of the
device itself and the through connection are independent from each other.
