(Ethernet Switches for industry)The Industrial Ethernet switch OnAccess746 has 4 1000Mbps optical ports with optional SFP module and 16 10/100Mbps electrical ports, which is designed to meet various industrial application needs, and provides customer with a high-end industrial Ethernet network communication solution. OnAccess746s high availability and reliability, as well as the rich security features, making it ideal for secure data transmission. The OnAccess746 provides powerful management capabilities, can be managed through Web, Command Line Interface (CLI), and Simple Network Management Protocol (SNMP). The OnAccess746 is designed with wide input range dual power supplies for redundancy, and supports DIN rail and panel mounting for installation in industrial environments.Fast Ring Protection (FRP) is a proprietary technology of Shenzhen First Mile Communications Ltd., designed specifically for industrial application, to provide a fast Ethernet ring protection and recovery in no more than 300 milliseconds. From management interface, user can choose any port (normal Ethernet port or trunk port) to form a Ethernet ring for faster recovering and wider bandwidth.Features Fast Ring Protection (FRP), Spanning Tree Protocol (STP), Rapid Spanning Tree Protocol (RSTP), Multiple Spanning Tree Protocol (MSTP), for Ethernet ring protection and quick recovery. 4K VLAN, supports 802.1Q, port based, protocol based VLAN, as well as Generic Attribute Registration Protocol (GARP), GARP VLAN Registration Protocol (GVRP) for flexible network planning and management Dual power input for high reliability Static and dynamic port aggregation for bandwidth management Port rate limit, broadcast storm control, port mirroring, rich Quality of Service (QoS) features for data traffic control and management Access Control Lists (ACL), blackhole MAC address filtering, secure Shell (SSH) v2.0, IEEE 802.1x, Static and dynamic MAC address management, for network security Web management interface, Command Line Interface (CLI), Simple Network Management Protocol (SNMP) v1, v2c, and v3 for enhanced network management.
