Antaira LMP-2812G-4X8S-T 28-Port 10G Managed Rackmount Industrial Switch with 16x PoE+, 4x 10G SFP+, 8x SFP and -40 to 75 °C

Racks in unheated buildings and shelters can sit well below freezing, yet the switch there may have to route traffic for a whole site and power 16 devices. The LMP-2812G-4X8S-T is the extended temperature model in the Antaira LMP-2812G-4X8S series, a 28-port Layer 3 managed industrial PoE+ switch for the rack, with 16 PoE+ ports and four 1G/2.5G/10G SFP+ slots and eight 1G SFP slots.

Sixteen 10/100/1000 RJ45 ports support IEEE 802.3at/af PoE+ at up to 30 W per port. The 480 W budget covers all 16 ports at 30 W at once. The four SFP+ slots run at 1, 2.5 or 10 Gbps and the eight SFP slots at 1 Gbps, with single-mode or multi-mode modules. Switching runs on a 128 Gbps fabric with a 32K MAC table, a 32 Mbit packet buffer and 10K jumbo frames.

Full Layer 3 routing covers static routes, OSPFv2/v3, RIPv2/RIPng and VRRPv2/v3, so the switch can route between subnets and share a gateway. ITU-T G.8032 ERPS, STP, RSTP, MSTP and LACP handle redundancy, and VLANs, QoS, IGMP snooping and Modbus TCP cover daily management. PoE scheduling, output limits and alive check control each port, and RADIUS, TACACS+, 802.1X, ACLs and IP Source Guard secure access. Redundant 48 to 55 V DC inputs have overload current and reverse polarity protection, and a 24 V DC, 1 A relay contact reports faults.

The LMP-2812G-4X8S-T runs fanless in an IP30 metal case for a 19-inch rack and draws 38.5 W itself, with a Telcordia MTBF of 166,201 hours. Antaira lists FCC, CE, UL 61010-1 and UL Class 1 Division 2 approvals, states NDAA and TAA compliance and covers it with its 5-year warranty. The LMP-2812G-4X8S is the -10 °C to 65 °C model, and the LMP-2812G-4X8S-24-T accepts 12 to 55 V DC. We supply and specify the switch, and can pre-configure IP addressing, VLANs, routing and ring settings on request.
