Olycom Serial over Ethernet PoE Fiber Switch
Key Features
1. Serial to Ethernet Integration in One Device
Built-in RS-232 / RS-422 / RS-485 interfaces allow legacy PLCs, meters, sensors, and controllers to communicate directly over IP networks, eliminating the need for external serial device servers.
2. Gigabit PoE for Edge Devices
Eight 10/100/1000Mbps RJ45 ports deliver both data and power to IP cameras, industrial terminals, and controllers, with intelligent PoE detection and a high total power budget suitable for dense field installations.
3. Fiber Uplinks for Long-Distance & Noise-Free Transmission
Dual Gigabit SFP slots provide flexible fiber connectivity, extending network reach and ensuring stable communication in electrically noisy industrial environments.
4. Industrial L2+ Managed Networking
Advanced Layer 2+ features such as VLAN, QoS, Link Aggregation, STP/RSTP/MSTP, and ERPSv2 enable resilient ring and redundant network topologies with fast recovery.
5. Secure & Scalable Management
Comprehensive security including 802.1X authentication, RADIUS, ACLs, HTTPS, SSH, and SNMPv3 ensures safe operation in OT and IT converged networks. Multiple management options via Web GUI, CLI, SNMP, and Cloud/MQTT simplify deployment and maintenance.
6. Rugged, Fanless Industrial Design
Compact IP40 aluminum enclosure, fanless cooling, and DIN-rail or wall mounting allow silent, maintenance-free operation in control cabinets and outdoor enclosures.
7. Reliable Power Architecture
Dual 48–56V DC redundant power inputs with alarm relay output protect against power failures and wiring errors, ensuring continuous operation in mission-critical applications.

NOTE:
1. RSTP switches to the ON position, which indicates RSTP is in disabled status.
2. VLAN switches to the ON position, indicating VLAN is enabled. All LAN ports can only communicate with the SFP uplinks when this option is enabled.
3. To take effect the DIP Switch function while the ethernet switch is in operation, there is a need to reboot the Ethernet switch after tuning the DIP switch.
