Description
The ORIGO OI3120 Industrial L2 Managed Switch is equipped with 8 x 1000Base-T RJ-45 ports and 12x100/1000Base-X SFP1 ports.
The ORIGO OI3120 is an industrial Layer 2 managed switch designed for building secure and fault-tolerant data transmission networks at sites with strict environmental requirements.
The ORIGO OI3120 switch operates within a wide temperature range from –40 to +75 °C and supports the connection of two independent DC power supplies with redundancy capability, such as the OI75WPSU, OI120WPSU, or OI240WPSU. It is resistant to vibration and electrostatic discharges up to 8 kV. The rugged metal casing with IP40 protection and a reliable fanless ventilation system ensure stable operation in stringent industrial environments.
The OI3120 switch’s features include support for static routing, virtual local area networks (VLANs), quality of service (QoS), multicast management, security functions, and user access control.
To enhance network performance and fault tolerance, the switch supports link aggregation (LACP), connection redundancy through STP/RSTP/MSTP protocols, and LoopBack Detection for preventing network loops. SCP and Fast Ring DIP switches allow to quickly activate broadcast storm control and ERPS function, ensuring minimal recovery time in case of a line failure within the ring.
1To establish a 100 Mbps connection, the interface must be configured to 100Base-FX full-duplex mode.
