Antaira LMX-1604G-4XS 16-Port 10G Layer 3 Managed Switches with 4x 10G SFP+ and Extended Temperature Options

Routing and 10G fiber usually live in a rack in an equipment room, while the cabinets out on site make do with Layer 2 switches and gigabit uplinks. As networks grow to more subnets and more cameras, that split can force traffic back and forth across the site. The Antaira LMX-1604G-4XS series is a family of Layer 3 managed industrial switches that puts routing and 10G SFP+ uplinks on a DIN rail, inside the cabinet.

Each LMX-1604G-4XS has 12 10/100/1000BASE-T RJ45 ports and four 1G/2.5G/10G SFP+ slots that take single-mode or multi-mode transceivers, switching store-and-forward on a 104 Gbps fabric with a 32K MAC table and a 32 Mbit packet buffer. Layer 3 routing covers static routes, OSPFv2/v3, RIPv2/RIPng and VRRPv2/v3, with ARP, NAT and DHCP option 82, so the switch can route between VLANs and subnets and share a gateway with a second unit. The firmware also covers VLAN, QoS with DSCP, IGMP and MLD snooping, LACP, LLDP, sFlow, RMON, DDMI and Modbus TCP, with RADIUS, TACACS+, 802.1X, ACLs, IP source guard, DHCP snooping, ARP inspection, SNMP v3, HTTPS and SSHv2 securing access. ITU-T G.8032 ERPS restores a broken ring in under 50 ms, with STP, RSTP and MSTP for other layouts.

The series offers two temperature grades. The LMX-1604G-4XS is the standard build, rated -10 °C to 65 °C for heated cabinets and equipment rooms, and the LMX-1604G-4XS-T is the extended temperature build, rated -40 °C to 75 °C for unheated enclosures. Both draw 24 W from redundant 12 to 48 V DC inputs, with every connection on the front panel. Both builds run the same firmware, so one configuration can be saved and restored over USB across a mixed site, and dual image protection keeps a fallback copy of the firmware if an upgrade is interrupted.

Antaira names power and utility, water and wastewater, oil, gas and mining, factory automation, security surveillance and ITS as applications for the LMX-1604G-4XS series, on SCADA and industrial control networks. The fanless IP30 metal housing mounts on a DIN rail or wall, with overload, reverse polarity and high EFT and ESD protection and a 24 V DC, 1 A relay. Antaira lists CE, FCC, RoHS and TAA and NDAA compliance, quotes an MTBF of 406,943 hours and covers the series with its 5-year warranty.
