NetPing POE 5 Switch GB322 has five ports: ETH1, ETH2, ETH3, ETH4, ETH5.
The ETH1 (PoE IN) port is located on the front panel of the device and used to apply power to the switch with the
help of PoE injector or othe PSE device.
equipped with an af/at PoE compatibility circuit. The power standard is determined by the switch - standard 3 for
IEEE 802.3af (PD 13W) and standard 4 for IEEE 802.3at (PD 25.5W).
The maximum allowable output current of the external power adapter must not exceed 1.5 A.
You can connect an external supply power unit with the voltage from 34 up to 52V and the power of no more than
80W(to power the switch itself, excluding POE consumers). It is allowed to have the power supply of POE and the
connection of an external power supply unit simultaneously (in this case, the device will be powered from an
external power supply unit).
NetPing POE 5 Switch GB322 can transmit power received from PoE injector or power supply to ports ETH2, ETH3,
ETH4, ETH5.
Attention! The PoE partner identification scheme do not work on ETH2, ETH3, ETH4, ETH5 ports. If the
corresponding switches are set to ON, power is always supplied without identifying whether the partner
supports PoE or not. Power is always supplied to both pairs for transmitting data and unused pairs (options A
and B of the PoE standard). It is impossible to choose one of the variants.
By default, the switch GB332 does not transmit power to ETH2, ETH3, ETH4, ETH5 ports. In order to power one or
several ports you have to set the switches on the back panel of the device to ON. The corresponding switch is
responsible for certain port: 2, 3, 4, 5 for ETH2, ETH3, ETH4, ETH5 ports correspondingly.
The supply voltage range on the ETH1 port is 30-50 V. The ETH1 port is
