Antaira LMP-1204G-SFP-bt 12-Port Gigabit Managed PoE++ Switches with 8x PoE++ (240W), 4x SFP and Extended Temperature Options

A PTZ camera with a heater, a wireless backhaul radio or a lighting controller can draw two or three times what an 802.3at port delivers, and running separate mains to each one defeats the point of PoE. The Antaira LMP-1204G-SFP-bt series answers that with four 90 W 802.3bt ports in a DIN-rail cabinet switch, alongside four PoE+ ports and four fiber slots, under Light Layer 3 management.

Every LMP-1204G-SFP-bt shares the same port layout. Ports 1 to 4 are 10/100/1000 RJ45 with IEEE 802.3bt PoE++ at up to 90 W, ports 5 to 8 deliver IEEE 802.3at/af at up to 30 W, and four 100/1000 dual-rate SFP slots carry single-mode or multi-mode fiber. A 240 W budget is shared across the PoE ports with budget protection, alive check and scheduling. Static routes and DHCP Option 82 sit on top of VLAN, QoS, IGMP and LACP, and ITU-T G.8032 ERPS restores the ring in under 50 ms. Switching runs on a 24 Gbps fabric, and redundant DC inputs have reverse polarity and overload protection with a relay contact for alarms.

The range splits by input, temperature and build. The LMP-1204G-SFP-bt takes 48 to 55 V DC and is rated -10 °C to 65 °C, and the LMP-1204G-SFP-bt-T extends that to -40 °C to 75 °C. The LMP-1204G-SFP-bt-24 and LMP-1204G-SFP-bt-24-T accept 12 to 55 V DC for cabinets without a 48 V rail, with the full budget at higher input voltages. The LMP-1204G-SFP-bt-T-CC is the conformal-coated version of the -T, and the LMP-1204G-SFP-bt-T-BOS-CC is the conformal-coated BOS build of the LMP-1204G-SFP-bt-T. The uncoated BOS builds are listed separately as the LMP-1204G-SFP-bt-T-BOS and LMP-1204G-SFP-bt-24-T-BOS.

Every LMP-1204G-SFP-bt model runs fanless in an IP30 metal case for DIN-rail or wall mounting and carries Antaira’s 5-year warranty. The main models list FCC, CE, UL 61010-1 and UL Class 1 Division 2 approvals with NDAA and TAA compliance, while the coated builds list UL 61010-1 and NEMA TS2. Antaira names surveillance, ITS, power and utility, water treatment, oil and gas and factory automation as the target networks, and the 802.3bt ports make the series a good fit wherever high-draw cameras or radios share a cabinet with fiber uplinks.
