Antaira LMX-2004G-SFP(-T) 20-Port Gigabit Managed Ethernet Switch with 4 SFP Slots

For projects that push the capacities of communication equipment, Antaira Technologies answers with the LMX-2004G managed industrial Ethernet switch. Available in two wide operating temperature ranges, it exceeds the throughput requirements of most applications while enduring the harshest environments. Add it to your network or replace older components to increase bandwidth and reduce cost.

This switch is loaded with Layer 2 and Layer 3 protocols to support network determinism, management, and security. It features RSTP/MSTP, Ethernet Ring Protection Switching (ERPS), QoS, IGMP, VLAN, RMON, Modbus TCP, HTTPS, SSL, alarming, fault handling, and backup.  It may be configured using a serial console interface, Command Line Interface (CLI) commands, Telnet, SSH, user-friendly Web GUI, or Simple Network Management Protocols (SNMP).

Performance and durability are basic elements of the LNX-2004G-SFP. Sixteen Gigabit RJ45 Ethernet ports and four fiber-optic SFP slots offer unlimited communication possibilities. It will connect a variety of data-intensive devices and handle large traffic loads without showing signs of buckling.  A power failure detection relay, dual-redundant power inputs, and surge protection enhance reliability.  It will remain operational even against the most unstable power source.  A fanless, metal housing resists dust, humidity, and temperature extremes from -40° to 75°C. The universal DIN-rail mounting bracket makes installation into a control panel or machine a breeze.  Backed by a 5-year warranty, the LNX-2004G-SFP can be trusted for critical operations.
