Antaira LMX-0804G-SFP 8-Port Managed Ethernet Switch with 4 Gigabit Ports and 4 SFPs

Engineers and network professionals count on Antaira’s Ethernet switches for two reasons -- performance and reliability. For critical automation and industrial operations, Antaira delivers with heavy-duty communication solutions that simply work – all the time, under all conditions.

The reliable LMX-0804G-SFP Ethernet switch meets the highest industrial standards.  It offers 8 Ethernet ports – 4 Gigabit ports (10/100/1000TX) and 4 SFP ports. Built-in Layer 2 management software enhances performance, reliability and security.  It features redundancy like Ethernet Ring Protection Switching (ERPS) protocol.  Common management functions include QoS, CoS, SNMP, IGMP, VLAN, IEE802.1Q, remote monitoring, alarming, event handling and backup.  Learn more about the LMX-0804G-SFP by downloading the user manual under the Downloads tab.

An industrial switch must endure temperature extremes, dirty power, humidity and dust.  Naturally, the LMX-0804G-SFP does.  It meets electrical and safety certifications required by the FCC, CE, IEC and IEEE.  You get redundant 48V input and built-in protection from voltage surges and current spikes. The metal case may be mounted to a wall or DIN-rail.  Select from two wide operating temperatures -- standard or extended for heat and cold extremes.
