Antaira LMP-2804G-4XS 28-Port 10G Managed Rackmount Industrial Switch with 24x PoE+ (720W) and 4x 10G SFP+

The switch at the aggregation point of an industrial network has to route between VLANs, power the local devices and push their traffic onto fast fibre, often from a single 19-inch rack. The LMP-2804G-4XS is the standard temperature model in the Antaira LMP-2804G-4XS series, a 28-port Layer 3 managed industrial PoE+ switch for the rack, with 24 PoE+ ports and four 1G/2.5G/10G SFP+ slots.

Twenty-four 10/100/1000 RJ45 ports support IEEE 802.3at/af PoE+ at up to 30 W per port. The 720 W budget covers all 24 ports at 30 W at once, so PoE never has to be rationed across the switch. The four SFP+ slots run at 1, 2.5 or 10 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-2804G-4XS runs fanless from -10 °C to 65 °C in an IP30 metal case for a 19-inch rack and draws 40.5 W itself, with a Telcordia MTBF of 142,643 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-2804G-4XS-T covers -40 °C to 75 °C, the LMP-2804G-4XS-24 accepts 12 to 55 V DC, and the LMP-2812G-4X8S trades eight PoE ports for eight more fibre slots. We supply and specify the switch, and can pre-configure IP addressing, VLANs, routing and ring settings on request.
