Antaira LMX-1802G-SFP Industrial 18-Port Managed Ethernet Switch with 16 Gigabit Ports and 2 SFP Slots

Reliability and performance are key components for devices connecting industrial networks. That’s why engineers and IT professionals count on Antaira Technologies for their communication needs.  The LMX-1802G-SFP managed Ethernet switch is ideal for critical applications that need to move and manage mass amounts of data.  It features 16 Gigabit ports and dual SFP slots for long-distance fiber-optic connections.  You’ll find this switch to be ideal for automation, intelligent transportation, security, and energy industries.

This switch is rich with Layer 2 network management functions.  It includes a user-friendly web interface for quick configuration and deployment.  It features open-standard Ethernet Ring Protection Switching (ERPS) to ensure network recovery in less than 50 milliseconds.  It implements QoS, SNMP, IGMP, VLAN, IEE802.1Q, alarming, fault handling, and backup.  

The reliability of the LMX-1802G-SFP is as good as its ability to transport enormous volumes of traffic.  It was engineered to endure harsh factory floor and outdoor conditions.  Select from a standard operating temperature of -10°C to 70°C or choose the optional extended temperature for extremely hot and cold locations. Clean power is always a worry in heavy industrial plants, and that is why this switch includes primary and secondary 48V power inputs and protection from voltage and current surges.  The switch is complete with safety and electrical certification and a 5-year warranty.
