Antaira LMP-1604G-4XS-bt 16-Port 10G Layer 3 Managed Switches with 12x PoE++ (360W), 4x 10G SFP+ and Extended Temperature Options

High-draw devices are spreading through industrial and outdoor networks: PTZ cameras with heaters, wireless radios and lighting that each want more than an 802.3at port can give, plus video streams that soon fill a gigabit uplink. The Antaira LMP-1604G-4XS-bt series brings twelve 802.3bt PoE++ ports, 10G fiber and full Layer 3 routing together in one fanless DIN-rail unit, with every connection on the front face.

Every LMP-1604G-4XS-bt has twelve 10/100/1000 RJ45 ports with IEEE 802.3bt PoE++ at up to 100 W each, sharing a 360 W budget managed with budget protection, PoE alive check, output scheduling and Antaira’s Persistent PoE. Four SFP+ slots run at 1, 2.5 or 10 Gbps. Switching runs on a 104 Gbps fabric with a 32K MAC table and a 32 Mbit buffer. Layer 3 routing covers static routes, OSPFv2/v3, RIPv2/RIPng and VRRPv2/v3, so the switch can route between VLANs and share a gateway with a partner unit, while ITU-T G.8032 ERPS restores the ring in under 50 ms. RADIUS, TACACS+, 802.1X, ACLs and IP Source Guard secure access, and Modbus TCP reports status to SCADA.

The series comes in two temperature grades. The LMP-1604G-4XS-bt is the standard build, rated -10 °C to 65 °C for heated or indoor cabinets. The LMP-1604G-4XS-bt-T is the extended temperature build, rated -40 °C to 75 °C for unheated outdoor enclosures. Within the Antaira range, the LMX-1604G-4XS series keeps the Layer 3 design and 10G slots without PoE, and the LMP-2804G-4XS series moves to 24 PoE+ ports in a 19-inch rack.

Power comes in on redundant 48 to 55 V DC inputs with overload current and reverse polarity protection, the switch draws 25 W, and a 24 V DC relay contact reports faults. Both LMP-1604G-4XS-bt models run fanless in an IP30 metal case for DIN-rail or wall mounting, with a Telcordia MTBF of 258,072 hours and Antaira’s 5-year warranty. Antaira lists FCC and CE marks and states NDAA and TAA compliance. It names power and utility, water treatment, oil and gas, factory automation, security surveillance and ITS as target networks, and the series suits any cabinet where several high-draw devices share 10G uplinks.
