8+4G/9+3G Port Layer 3 Managed EN50155 Industry Ethernet Switch
Product Overview

The Aquam8512A series switches, specially designed for rail industries, support up to 8 Fast Ethernet interfaces and 4 Gigabit uplink interfaces, support panel mounting, support a  wide range of operation temperature(-40℃ to 75℃), and meets the EN50155, EN50121 and other rail transit industry standard. The switches support IP67  protection class to meet the requirements of dustproof and waterproof performance, and support M12 interface form to ensure the tightness and the   firmness of the connection port, which especially suitable for application   that are subject to high vibration and shock. 
The Aquam8512A series switches support PoE function, support Isolated power   supply of a wide range (Power input range is up to 24VDC-110VDC), provide 9   fast Ethernet M12 ports with 9 IEEE 802.3at PoE+ (compatible with IEEE802.3af) ports, and can be used to power up to 9 IEEE 802.3at compliant   powered devices (PDs), eliminating the need for additional wiring. The switches are classified as power source equipment (PSE) and provide maximum PoE power up to 30 watts per port and a total of 60 watts for the whole PoE port. 
The Aquam8512A series switches support Layer 3 routing protocols such as OSPF v2.0, and supports IGMP protocol and PIM protocol to implement multicast   routing, support DHCP protocols for automatic IP address assignment, and support DRP, DT Ring and RSTP ring network redundancy protocol for flexible networking in order to meet the market demand of railway.The switches can be widely used in PIS, CCTV, video monitoring system and train control system, also apply to any other industrial applications of harsh vibration and shock, and high EMC compatibility.
