Antaira LMP-1204G-SFP-bt-T 12-Port Gigabit Managed PoE++ Switch with 8x PoE++ (240W), 4x SFP and -40 to 75 °C

Outdoor poles and roadside enclosures on ITS, surveillance and utility networks are often unheated, yet the switch inside may have to feed a PTZ camera with its own heater through the coldest night of the year. The LMP-1204G-SFP-bt-T is the extended temperature, 48 V model in the Antaira LMP-1204G-SFP-bt series, a 12-port Light Layer 3 managed industrial switch rated -40 °C to 75 °C.

Four 10/100/1000 RJ45 ports deliver IEEE 802.3bt PoE++ at up to 90 W per port, four more deliver IEEE 802.3at/af at up to 30 W, and four 100/1000 dual-rate SFP slots handle fibre uplinks with single-mode or multi-mode modules. A 240 W PoE budget is shared across the eight ports, managed with budget protection, PoE alive check, output scheduling and Persistent PoE. Static routes, ARP, NAT and DHCP Option 82 add Light Layer 3 functions to the VLAN, QoS, IGMP and LACP toolset, and ITU-T G.8032 ERPS heals the ring in under 50 ms.

Redundant 48 to 55 V DC inputs are protected against overload current and reverse polarity, and a 24 V DC, 1 A relay contact signals faults. The switch draws 12.5 W of its own. RADIUS, TACACS+, 802.1X, ACLs and IP Source Guard secure management, with web, CLI, Telnet and SNMPv3 access.

The LMP-1204G-SFP-bt-T runs fanless in an IP30 metal case for DIN-rail or wall mounting, with a Telcordia MTBF of 342,877 hours. Antaira lists FCC, CE, UL 61010-1 and UL Class 1 Division 2 approvals, states NDAA and TAA compliance and adds its 5-year warranty. The LMP-1204G-SFP-bt is the -10 °C to 65 °C model, the LMP-1204G-SFP-bt-24-T accepts 12 to 55 V DC, and the LMP-1204G-SFP-bt-T-CC adds conformal coating. We supply and specify it, and pre-configure IP addressing, VLANs and ring settings where you ask.
