Antaira LMP-2004G-SFP 20-Port Gigabit Managed DIN Rail Switches with 16x PoE+ (240W), 4x SFP and Extended Temperature Options
The Antaira LMP-2004G-SFP series is a family of Light Layer 3 managed industrial PoE+ switches with sixteen 30 W 802.3at/af RJ45 ports on a 240 W budget, four 100/1000 SFP slots, G.8032 ERPS ring recovery under 50 ms and redundant 48 to 55 V DC inputs, with IEC 61850-3 and NEMA TS2 approvals. The series suits power and utility, water treatment, factory automation, ITS and surveillance networks.
- Sixteen PoE+ Plus Four SFP: Sixteen 30 W 802.3at/af RJ45 ports on a 240 W budget and four 100/1000 SFP slots for ring links and branches.
- Light Layer 3 Functions: Static routes and DHCP Options 66, 67 and 82 alongside VLAN, QoS, IGMP, LACP and Modbus TCP management.
- G.8032 Ring Under 50 ms: ITU-T G.8032 ERPS restores a broken ring in under 50 ms, with STP, RSTP and MSTP for other topologies.
- Redundant 48 to 55 V DC: Dual DC inputs with overload and reverse polarity protection, an 18.4 W system draw and a relay contact for alarms.
- IEC 61850-3 and NEMA TS2: IEC 61850-3 Edition 2.0, NEMA TS2 and UL 61010-1 approvals in a fanless IP30 metal DIN-rail case.

LMP-2004G-SFP Description
A fibre ring takes two ports on every switch in it, so a cabinet that also needs a fibre branch to a remote building or a second uplink soon runs out of slots. The Antaira LMP-2004G-SFP series gives a 16-port PoE+ cabinet four fibre slots, enough for the ring and two more links, in a 20-port Light Layer 3 managed industrial PoE+ switch for the DIN rail.
Every LMP-2004G-SFP has sixteen 10/100/1000 RJ45 ports with IEEE 802.3at/af PoE+ at up to 30 W each, sharing a 240 W budget, and four 100/1000 SFP slots for single-mode or multi-mode modules. Store-and-forward switching runs on a 40 Gbps fabric with an 8K MAC table and 9.6K jumbo frames. The firmware covers 802.1Q VLANs, QoS, IGMP v1/v2 snooping, LACP, Modbus TCP, IPv4/IPv6 and DHCP Options 66, 67 and 82, adds static routes, and uses ITU-T G.8032 ERPS to restore the ring in under 50 ms. 802.1X, SNMPv3, HTTPS, SSH and port lock secure access, and an RS232 console and USB backup make unit swaps quick.
The series comes in two temperature grades. The LMP-2004G-SFP is the standard build, rated -10 °C to 70 °C for heated or indoor cabinets. The LMP-2004G-SFP-T is the extended temperature build, rated -40 °C to 75 °C for unheated outdoor enclosures. Within the Antaira range, the LMP-1802G-SFP series keeps the 16 PoE+ ports with two SFP slots, the LMP-2012G-SFP series trades copper for twelve SFP slots, and the LMX-2004G-SFP series offers the same layout without PoE.
Power comes in on redundant 48 to 55 V DC inputs with overload current and reverse polarity protection, the switch draws 18.4 W, and a relay contact reports power or port faults. Both LMP-2004G-SFP models run fanless in an IP30 metal case for DIN-rail or wall mounting and carry Antaira’s 5-year warranty. Antaira lists FCC, CE, UL 61010-1 and NEMA TS2 approvals, with IEC 61850-3 Edition 2.0 for substations, and names power and utility, water treatment, oil and gas, factory automation, ITS and security surveillance as target networks. The four fibre slots make the series a good fit for ring-connected cabinets that also feed a remote building or need a second uplink.

Official Antaira UK Distributor
Things Embedded is an official Antaira UK distributor, supplying the LMP-2004G-SFP series for UK utility, water, factory automation, ITS and surveillance programmes. Within the Antaira range, the LMP-1802G-SFP keeps the 16 PoE+ ports with two SFP slots where a single ring is enough, and the LMP-2012G-SFP moves to eight PoE+ ports and twelve SFP slots for fibre-heavy cabinets.
The LMP-2004G-SFP series sits among our PoE switches for industrial sites, our managed switches for industrial networks and our industrial Ethernet switches. Where a 16-device PoE cabinet sits in a fibre ring and needs spare fibre ports, this is the Antaira series to specify. We supply and specify it, and can pre-configure IP addressing, VLANs and ring settings to suit the site.
