1. Introduction
All Antaira industrial managed switches come with a pre-installed “user-friendly” web console
interface, which allows users to easily configure and manage the units, whether one is using a
serial console and command line interface(CLI) commands like Telnet, SSH, HTTP (Web GUI) or
simple network management protocols (SNMP).
1.1 Product Overview
Antaira Technologies’ LMX-1204G-SFP series is a 12-port industrial Gigabit managed Ethernet
switch embedded with 8*10/100/1000Tx Ethernet ports and 4*100/1000 dual rate SFP slots for
fiber connections. The LMX-1204G-SFP is a fully manageable Layer 2 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, RMON, Modbus TCP, and
802.1X/HTTPS/SSH/SSL increase determinism and improve network management for remote
SCADA systems or control networks.
The LMX-1204G-SFP series is IP30 rated and DIN-rail mountable. There are also two wide
operating temperature models for either a standard temperature range (STD: -10°C to 70°C) or an
extended temperature range (EOT: -40°C to 75°C). It also provides high EFT and ESD protection
for industrial networking applications, such as, power/utility, water wastewater, oil/gas/mining,
factory automation, security surveillance, ITS and any other outdoor or harsh environment.
