Antaira LMP-0804G-SFP 8-Port Gigabit Managed DIN Rail Switches with 4x PoE+, 4x SFP and Extended Temperature Options

Four fiber ports let one switch join a ring and still run spurs to remote cabinets on fiber, while four PoE+ ports power devices on site. The Antaira LMP-0804G-SFP series is built around that split, with four gigabit PoE+ ports, four dual-rate SFP slots that take single-mode or multi-mode modules, and Layer 2 management in a DIN-rail case.

Every LMP-0804G-SFP switch shares the same design. Each switch has four 10/100/1000Base-TX RJ45 ports with IEEE 802.3af/at PoE+ and four 100/1000 dual-rate SFP slots that take single-mode or multi-mode modules, on a 16 Gbps store-and-forward fabric with an 8K MAC table. Management is Layer 2 with IEEE 802.1Q VLANs, IEEE 802.1p QoS, IGMP v1/v2 multicast filtering, LACP, SNMP v1/v2c/v3, RMON and DHCP Option 66/67/82. ITU-T G.8032 ERPS restores a broken ring in under 50 ms, alongside STP, RSTP and MSTP, and Modbus TCP supports SCADA monitoring. Set-up is by web console, Telnet or CLI, with IEEE 802.1X, HTTPS and SSH/SSL for secure access. MAC-based port lock blocks unauthorised access, a PoE Ping Alarm can power-cycle PoE ports, and a USB 2.0 port backs up the configuration. Power arrives on 48 V to 55 V DC redundant inputs through a removable 6-pin terminal block. Each PoE+ port delivers 25 W from a 48 V DC supply and the full 30 W from 51 V to 55 V DC. Overload current, reverse polarity, EFT and ESD protection are built in, and exceptions can trigger an e-mail alert or the relay output.

The series offers two temperature builds. The LMP-0804G-SFP is the standard build, rated -10 °C to 70 °C for heated cabinets and indoor plant. The LMP-0804G-SFP-T is the extended temperature build, rated -40 °C to 75 °C for unheated outdoor enclosures. For eight PoE+ ports and no fiber the LMP-0800G series is the nearest range, and the LMX-0804G-SFP series is the version without PoE.

Antaira names power and utility, water and wastewater, oil, gas and mining, factory automation, security surveillance and ITS among the applications for the LMP-0804G-SFP series. Standard builds run from -10 °C to 70 °C and -T builds from -40 °C to 75 °C, so the same switch can serve an indoor panel and an unheated roadside or utility enclosure. Every model has an IP30 metal housing for DIN-rail or optional wall mounting, is designed to IEC 60068-2-27 shock and IEC 60068-2-6 vibration, and Antaira lists FCC, CE and UL 61010-1 certifications with RoHS compliance. Every model carries Antaira’s 5-year warranty. We supply the LMP-0804G-SFP series and can pre-configure IP addressing, VLANs and ring settings before the switches ship.
