Antaira LNX-2012GN-SFP 20-Port Managed Ethernet Switch with 8 Gigabit Ports and 12 SFP Slots

Quality and performance are why engineers and networking specialists count on Antaira Technologies for their Ethernet needs.  The LNX-2012GN-SFP 20-port managed Ethernet switch is no exception.  With a high-density port count offering both Ethernet and fiber, it was designed to handle demanding communications for applications like factory automation, intelligent transportation, camera surveillance, and utility substations.

The 20 ports consist of 8 RJ45 Gigabit (10/100/1000TX) ports and 12 SFP (10/1000 FX) slots for fiber optic connections.  Built-in Layer 2 management software enhances performance, reliability, and security.  It features network functions like QoS, CoS, SMTP, IGMP snooping, SNMP, STP, RSTP, MSTP, IEEE 1588v2 clock synchronization, jumbo frames, VLAN, IEE802.1x,  IPv4/IPv6, RMON, MIB II, port mirroring, event Syslog, alarming, DNS, NTP/SNTP, HTTPS, SSH/SSL, TFTP and a whole lot more.

The LNX-2012GN-SFP industrial switch was engineered to withstand wide temperature ranges, unreliable power, humidity, and dust.  It meets electrical and safety certifications required by the FCC, CE, IEC, and IEEE.  You get dual-redundant 48 VDC inputs with built-in protection from reverse polarity, voltage spikes, and current surges.  The LNX-2012GN-SFP Ethernet switch comes with documentation, DC power cable, serial console cable, DIN-rail and wall mount brackets, and a 5-year warranty.
