Features > Ŝ! Worldwide fastest Redundant Ethernet Ring (Recovery time < 10ms over 250 units connection) > Ŝ! Supports Ring Coupling, Dual Homing, iA-Ring > The EH6508G-F Series is a managed redundant Ring Ethernet switch with 6x10/100TX and 2x 1000LX. The EH6508G-F can protect your mission-critical applications from network interruptions or temporary malfunctions with its maximum 10ms ultra fast recovery time. It also supports network management functions, such as SNMP, RMON and Port/Tag-based VLAN security. Therefore, it makes EH6508G-F Series the best choice for highly-managed and Fiber Ethernet application. Ŝ! Supports SNMPv1 / v2 / v3 & RMON & Port base / 802.1Q VLAN Network Management > Ŝ! Event notification by Email, SNMP trap and Relay Output > Ŝ! Web-based, Telnet, Console, CLI configuration > Ŝ! Redundant DC power inputs (terminal block & DC-Jack) Worldwide Fastest Recovery Time: <10ms > Ŝ! Windows utility(Ether manager) for network manage-ment > The EH6508G-F Series supports the fastest 10ms redundant recovery time which make a non-stop Ethernet connection. If your primary communication path is disconnected, Redundant Ring Technology would provide a redundant path in the network. Its maximum 10ms ultra fast recovery time allows the EH6508G-F Series Ethernet Switch to supply a solid foundation of highly fault-tolerant and easily-managed network. Ŝ! Overload current protection > Ŝ! Reverse polarity protection Network Management and Remotely Configured > The EH6508G-F Series can be configured smartly by web browser, Telnet, CLI, and windows utility. Network administrators can define sending event notification by E-mail, SNMP trap, or relay output, as well as segment ports into different VLANs, or filter multicast traffic by IGMP Snooping. To enhance the security, port access can be limited to pre-defined IP address table. Network determinism is answered by QoS for traffic prioritization. Redundant Power Input > The redundant DC power inputs guarantee a non-stop operation. The backup power input will take over immediately when the primary DC power input fails. Relay Output Alarm by Port Break or Power Failure > The EH6508G-F Series provides relay outputs that can be set up to indicate events with different importance to notify or warn engineers in the field, so the engineer can use the appropriate emergency mainte- nance procedures to respond quickly to higher priority messages.
