Chapter 4: Hardware interfacesLAN interface 534444Hardware interfaces4.7 LAN interface4.7.1 OverviewThe terminal has four Ethernet LAN ports with Power over Ethernet (PoE). TheEthernet ports are standard IEEE 802.3 af ports using RJ-45 connectors.4.7.2 Power over Ethernet (PoE)One power supply powers all four interfaces with a floating 48 V DC supply(44 - 57 V DC). Therefore, the interfaces are not galvanically separated fromeach other. All Tx signals are DC connected to the Positive PoE Voltage and allRx signals to the Negative PoE Voltage.The total output power from all 4 interfaces is set to 61.2 Watt, so all interfacescan support devices of power class 1, 2 and 3 (4, 7 and 15.4 Watt).In case of power hold-up (failure on input power), PoE will be turned off.
