Antaira LMX-0602-V2 6-Port Fast Ethernet Managed Industrial Network Switches with 2x 100FX SC Multi-mode Fibre and Extended Temperature Options

Many SCADA and control networks still run at 100 Mbps, and what they need from a switch is not more bandwidth but a dependable fibre path between cabinets that may be kilometres apart. The Antaira LMX-0602-V2 series provides that with two fixed 100Base-FX fibre ports and four managed Fast Ethernet copper ports, in an IP30 metal DIN rail case, so no transceivers have to be chosen or stocked.

Every model shares the same Version 2 hardware. The four 10/100Base-TX RJ45 ports support auto MDI/MDI-X, and the two 100Base-FX ports use SC connectors. Switching is store-and-forward on a 1.2 Gbps fabric with an 8K MAC table and 9.6 KB jumbo frames. The Layer 2+ firmware covers IEEE 802.1Q VLANs, QoS, IGMP snooping for up to 1024 groups, LACP, IPv4/IPv6, DHCP Option 66/67/82, Modbus TCP and 802.1X, and adds static routes between VLANs. The two fibre ports form an ITU-T G.8032 ERPS ring that recovers in under 50 ms, with STP, RSTP and MSTP supported. Redundant 12 to 48 V DC inputs, a power lost relay alarm and a 7.5 W draw complete the design.

The four models split by fibre and temperature. The LMX-0602-M-V2 has multi-mode SC fibre to 2 km, rated -10 °C to 70 °C, and the LMX-0602-M-T-V2 is its extended temperature build, rated -40 °C to 75 °C. The LMX-0602-S3-V2 has single-mode SC fibre to 30 km, rated -10 °C to 70 °C, and the LMX-0602-S3-T-V2 is its extended temperature build for unheated outstations. Multi-mode suits links across a site; single-mode suits runs between sites.

Antaira names power and utility, water and wastewater, oil, gas and mining, factory automation, security surveillance and ITS as typical applications for the LMX-0602-V2 series, with high EFT and ESD protection and reverse polarity protection built in. Each case is tested for shock to IEC 60068-2-27, vibration to IEC 60068-2-6 and free fall to IEC 60068-2-32, with storage from -40 °C to 85 °C and 5% to 95% non-condensing humidity. Each switch is managed through the web console, Telnet, SSH or CLI, with an RS232 console port on RJ45. The series is UL 61010-1 certified, carries FCC and CE marks and comes with Antaira’s 5-year warranty, and we can pre-configure ring settings, VLANs and IP addressing before it ships.
