LAN interface
Overview
The terminal has two Ethernet LAN ports with Power over Ethernet (PoE). The Ethernet ports are
standard IEEE 802.3 af ports using RJ-45 connectors.
Power over Ethernet (PoE)
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.
