LAN interface
The terminal has two Ethernet LAN ports with Power over Ethernet (PoE). The PoE standard for
the Ethernet ports is IEEE 802.3af, and the connectors are RJ-45 connectors.
Power over Ethernet (PoE)
The LAN connectors have PoE, which means they can be used to supply power to connected
equipment, e.g. IP handsets. One power supply powers both interfaces with a floating 48 V DC
supply (44 - 57 V DC). Therefore, the interfaces are not galvanically separated from each other.
Both Tx signals are DC connected to the Positive PoE Voltage and both Rx signals to the
Negative PoE Voltage.
The total output power from the interfaces is 32 W. Both interfaces can support devices of
power class 1, 2 and 3 (4, 7 and 15.4 Watt), as long as the total power consumption does not
exceed the above limits.
In case of power hold-up (failure on input power), PoE will be turned off.
Pinout
The figure and table below show the connector outline and pin assignments.
Equipment connected to the LAN (PoE) connectors must comply with the PoE
standard IEEE 802.3af.
Pin number Pin function
1 TxD+ input (positive PoE)
2 TxD-input (positive PoE)
3 RxD+ output (negative PoE)
4 Not connected
5 Not connected
6 RxD- output (negative PoE)
7 Not connected
8 Not connected
