Description
The ORIGO OS3254M is a managed L3 switch with 24x1000Base-T RJ-45 ports, 24x100/1000Mbps SFP slots, and 6x10G SFP+ uplinks.
The OS3254M switch is designed for deployment in enterprise and ISP networks, delivering a high-performance and resilient distribution-layer solution with 10G connectivity and a high density of both copper and fiber Gigabit interfaces.
The OS3254M is equipped with three fan modules with automatic speed control and two hot-swappable AC power modules. Built-in 6kV surge protection meets industry surge standards, guarding the switch and connected devices from damage and network instability caused by ESD and lightning-induced surges. This design guarantees continuous availability and fault tolerance in mission-critical environments.
The switch combines powerful L3 routing capabilities (RIP, IS-IS, OSPF, BGP, PIM) with advanced security, QoS, and flexible VLAN features. Designed for reliable performance, the switch supports link aggregation (LACP, MLAG), redundancy protocols (STP/RSTP/MSTP), and ERPS technology for fast recovery in case of link failure within a ring topology. Built-in OAM tools provide comprehensive monitoring and troubleshooting, making network management simple and efficient.
