Antaira LNP-1802G-SFP-T 18-Port Gigabit Unmanaged Industrial Ethernet Switch with 16x PoE+ (240W), 2x SFP and -40 to 75 °C

Large camera schemes often gather 16 or more devices in one cabinet, then send everything back to the control room over a single fibre pair with a spare. The LNP-1802G-SFP-T is the extended temperature build in the Antaira LNP-1802G-SFP series: an unmanaged industrial PoE switch with 16 PoE+ ports and two SFP slots, rated -40 °C to 75 °C for unheated enclosures exposed to outdoor temperatures.

Sixteen 10/100/1000Base-T(X) RJ45 ports follow IEEE 802.3at at up to 30 W per port, and two dual-rate 100/1000 SFP slots take the fibre uplink and a second path, with the reach set by the transceiver chosen. Switching is store-and-forward on a 36 Gbps fabric with an 8K MAC address table, 9.6 KB jumbo frames, a 4 Mbit buffer and IEEE 802.3x flow control. There is no management interface, so it passes traffic as soon as it is powered.

Power arrives on redundant 48 to 55 V DC inputs on a removable 6-pin terminal block, with a slow-blow fuse for overload current, reverse polarity protection and high EFT and ESD protection. The 240 W PoE budget is shared: it covers eight ports at the full 30 W, or all 16 at an average of 15 W, which suits many fixed cameras. A relay output rated 1 A at 24 V DC warns a PLC or alarm panel if one supply fails, and the LNP-1802G-SFP-T draws up to 15 W itself.

The switch sits in an IP30 metal case for DIN rail or wall mounting, with shock and vibration ratings to IEC 60068-2-27 and IEC 60068-2-6. Antaira names security video surveillance, GigE machine vision, process control automation and intelligent transportation as typical applications, lists UL 61010-1 certification with FCC, CE and RoHS marks, and backs it with Antaira’s 5-year warranty. The LNP-1802G-SFP is the same switch rated -10 °C to 65 °C, the LNP-2004G-SFP adds two more SFP slots, and the LNX-1802G-SFP keeps the 16 plus two layout without PoE.
