PM 1001484 000 08 Device handbook SINEAX DM5000 36/966.4.3 Connection of the IEC61850 interfaceThe RJ45 sockets X1 and X2 serve for direct connecting Ethernet cables. Both ports are equivalent andinternally connected via a switch. Interface: RJ45 sockets, Ethernet 100BaseTX Mode: 10/100 MBit/s, full / half duplex, Auto-negotiation Protocols: IEC61850, NTPFunctionality of the LED's• LED green: On if a network connection (link) exists, flashes during communication6.4.4 Connection of the PROFINET interfaceThe RJ45 sockets X1 and X2 serve for direct connecting Ethernet cables. Both ports are equivalent andinternally connected via a switch.Note: The interface may only be connected to a local Profinet network, which is designed as SELV circuitaccording to IEC 60950-1.
