This unmanaged industrial ETHERNET switch (852-1102) has 8 Gigabit ETHERNET ports for easily setting up small- to medium-sized networks. Its slim design paired with a DIN-rail adapter simplifies installation in the control cabinet and provides high vibration and shock resistance. Additionally, automatic transmission rate detection (auto-negotiation) and automatic identification of the transmit and receive lines (Auto MDI-X) allow simple plug-and-play operation, saving time and money during commissioning. Status LEDs, a redundant power supply and an alarm contact (configurable via DIP switch) increase the switch's redundancy and diagnostic capabilities, providing higher operational uptime. Features: Redundant DC power supply Large supply voltage range: 9 … 57 V DIP switch to set alarm functions Full compliance with IEEE 802.3, 802.3u and 802.3ab standards Non-blocking, store-and-forward switching Auto-negotiation at all 10/100/1000BASE-T ports Auto-MDI/MDIX (crossover) at all 10/100/1000BASE-T ports Integrated address look-up table, supports up to 8000 absolute MAC addresses Overvoltage protection Prioritization of ETHERNET data packets (PROFINET protocol, EtherType=0x8892) per IEEE802.1p
