Element Function
ETH2..5 4xETH 10/100/1000 BASE-TX PoE in
There are four Ethernet 10/100/1000-BASE-TX PoE out on the back panel of the device. There four connectors are of
the IEEE 802.3af / 802.3at standard without the function of without the function of determining a compatible POE
device Power supply to the PoE out ports is manually configured using switches on the back panel.
Power supply
The device is delivered without a power supply in a delivery package. The device can be powered from POE of the
Ethernet network or you can connect an external power supply unit with the voltage fro 34V 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).
To connect an external power supply, use the DJK-02A connector with a 2.1 mm pin. The power connector polarity:
pin "+" coating "GND".
As an external power supply unit for the switch we recommend you to use Power adapter 48V 1.5A .
The maximum allowable output current of the external power adapter must not excede 1.5A
If it is necessary to operate the device as a POE injector for other devices in the network supporting the IEEE
802.3af/at standard, use a 48 V power supply! The power of the power supply unit must be sufficient to provide
the total power consumption of the switch itself and all POE consumers which are connected to it.
