This is a professional dual-redundant power supply industrial Ethernet switch designed for broadcast, live sound, industrial automation, and AV system integration.

The device features 16 snap-in (RJ45) Gigabit Ethernet ports and 4 SFP fiber optic ports, supporting high-speed data transmission and long-distance fiber connections (>10 km).

The dual redundant power supply design ensures high availability, utilizing a DC 12V 1A power input for stable and reliable power delivery.

This switch delivers an optimal balance of port density, redundancy reliability, and industrial-grade durability, making it ideal for backbone network deployments in harsh environments.

Product Features

• Dual redundant power supply: Supports dual power inputs (primary/backup) with automatic switching < 5 ms, ensuring zero-interruption operation;
• High-density ports: 16 Gigabit RJ45 snap-in ports (10/100/1000 Mbps auto-negotiation) + 4 SFP fiber slots (supports 100/1000 Mbps multimode/single-mode modules);
• Unmanaged design: Plug-and-play operation compliant with IEEE 802.3 standard, featuring automatic MDI/MDI-X crossover detection for simplified deployment;
• Industrial-grade protection: IP30-rated metal housing with extended operating temperature range (-40°C～75°C), supporting shock/dust resistance;
• Long-distance transmission: SFP ports support fiber links >10 km, RJ45 ports support Cat5e/6 cables >100 m;
• Low power consumption and heat dissipation: Passive cooling design, fanless, <15 W power consumption, suitable for noise-sensitive environments;
• Monitoring Indicators: LED displays for power status, link/activity, and SFP connection for easy field diagnostics.
