Key Performance Highlights

• The switch recovers ring topology faults in under 20 ms across 250 switches.
• The wide-temperature design keeps full performance from -40 to 75 °C.
• Three fiber uplinks extend network reach up to 5 km without copper limits.
• The 8 K MAC table handles dense device populations on one segment.
• Redundant dual power inputs keep the switch alive during supply failures.
• EtherNet/IP and Modbus TCP support direct integration with PLC and SCADA systems.

Installation Guide

• Mount the unit on a standard 35 mm DIN-rail inside a protected cabinet.
• Wire both DC inputs to separate 12/24/48 VDC sources for redundancy.
• Verify polarity before power-up; the switch protects against reverse connection.
• Connect copper devices to the five RJ45 ports using shielded Cat5e cable.
• Attach OM1 multi-mode fiber patch cords to the three ST fiber ports.
• Access the web UI through the default management IP and set a strong password.
• Enable Turbo Ring on the ring ports to activate sub-20 ms fault recovery.
• Keep ambient temperature within -40 to 75 °C for rated operation.
