Antaira Technologies’ LMX-2812G-4X8S is a 28-port industrial gigabit managed Ethernet switch featuring 16 Gigabit Ethernet ports, 4 1Gigabit/2.5Gigabit/10Gigabit SFP+ Slots, and 8 Gigabit SFP Slots. This makes the product ideal for applications that demand high density of port connectivity, wide bandwidth and long-distance communication.
The LMX-2812G-4X8S is a fully manageable Light Layer 3 Ethernet switch that is pre-loaded with a user-friendly web management console design. It supports the ring network redundancy function using the market’s open standard ITU-T G.8032 ERPS (Ethernet Ring Protection Switch) protocol that has a <50ms network recovery time. The advanced network filtering and security functions, such as IGMP, VLAN, QoS, SNMP, port lock, RMON, Modbus TCP, and 802.1X/HTTPS/SSH/SSL increase determinism and improve network management for remote SCADA systems or control networks.
The LMX-2812G-4X8S is packaged in an IP40 rated rugged 1U rack-mount metal case. An extended temperature option (LMX-2812G-4X8S-T) of -40 to 75°C makes it the best solution for any harsh and extreme ambient weather environment applications, such as power/utility, transportation, water wastewater treatment plant, oil/gas, and security surveillance system industries. Backed by Antaira’s 5-year warranty, you know your equipment investment will last.
LMX-2812G-4X8S, Standard operating temperature, -10° to 65°C
LMX-2812G-4X8S-T, Extended operating temperature, -40° to 75°C
