Antaira LMX-2004G-SFP-T 20-Port Gigabit Managed Industrial Ethernet Switch with 4x SFP and -40 to 75 °C

The LMX-2004G-SFP-T is the extended temperature build of the Antaira LMX-2004G-SFP series: a 20-port Light Layer 3 managed industrial switch with 16 gigabit RJ45 ports and four SFP slots, rated -40 °C to 75 °C for unheated outdoor and roadside cabinets.

  • Extended -40 °C to 75 °C Rating: Rated -40 °C to 75 °C for unheated outdoor, utility and roadside cabinets, with storage from -40 °C to 85 °C.
  • 16 Gigabit RJ45 Ports: Sixteen 10/100/1000Tx RJ45 ports with auto MDI/MDI-X on a 40 Gbps fabric for cameras, controllers and HMIs.
  • Four 100/1000 SFP Slots: Four dual-rate SFP slots take single-mode or multi-mode transceivers, enough to close a ring and run two fibre spurs.
  • Light Layer 3 with G.8032 ERPS: Static routes and DHCP option 82 sit alongside G.8032 ERPS ring recovery in under 50 ms and STP, RSTP and MSTP.
  • IEC 61850-3 and Redundant DC Input: Antaira lists IEC 61850-3 Edition 2.0, UL 61010-1 and NEMA TS2, with redundant 12 to 48 V DC inputs.

LMX-2004G-SFP-T Overview

Unheated outdoor cabinets in power and utility, water treatment and ITS networks often have to close a fibre ring and send fibre spurs onward from the same switch. The LMX-2004G-SFP-T is the extended temperature build of the Antaira LMX-2004G-SFP series: a 20-port managed industrial Ethernet switch rated -40 °C to 75 °C.

Sixteen 10/100/1000Tx RJ45 ports auto-negotiate speed and duplex with auto MDI/MDI-X, and four 100/1000 SFP slots take fibre transceivers, so the mode and reach follow the module chosen. Two slots can close a ring while the other two carry spurs to remote cabinets. Switching is store-and-forward on a 40 Gbps fabric with an 8K MAC table and 9.6K jumbo frames, and ITU-T G.8032 ERPS restores a broken ring in under 50 ms. An RS232 console in RJ45 and USB 2.0 configuration backup help on site.

Light Layer 3 on the LMX-2004G-SFP-T means static routes and DHCP option 82, so it can pass traffic between subnets and relay addressing requests without a separate router. The firmware also covers VLAN with 4095 groups, QoS with DSCP, IGMP and MLD snooping, LACP, LLDP, sFlow, RMON and Modbus TCP for SCADA polling, with 802.1X, SNMP v3, HTTPS and SSHv2 securing access. Power arrives on redundant 12 to 48 V DC inputs through removable terminal blocks, and the switch draws 18.4 W with overload current and reverse polarity protection. We can pre-configure IP addressing, VLANs and ring settings before it ships.

The LMX-2004G-SFP-T operates from -40 °C to 75 °C and stores from -40 °C to 85 °C, so it suits unheated outdoor enclosures without a cabinet heater. It sits in an IP30 metal housing for DIN rail or wall mounting, with IEC 60068-2-27 shock and IEC 60068-2-6 vibration listed. Antaira lists FCC, CE, UL 61010-1, NEMA TS2 and IEC 61850-3 Edition 2.0 for substations, and the switch is RoHS compliant with Antaira’s 5-year warranty. The LMX-2004G-SFP is the standard temperature build rated -10 °C to 70 °C, and the LMP-2004G-SFP adds 802.3at PoE+ to the 16 copper ports with a 240 W budget.
