Antaira LNP-2004G-SFP-T 20-Port Gigabit Unmanaged Industrial Network Switch with 16x PoE+ (240W), 4x SFP and -40 to 75 °C

A high-density camera cabinet that also sits on a fiber ring, or passes fiber on to other cabinets, needs both a large PoE port count and several fiber ports. The LNP-2004G-SFP-T is the extended temperature build in the Antaira LNP-2004G-SFP series: an unmanaged industrial PoE switch with 16 PoE+ ports and four 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 four dual-rate 100/1000 SFP slots take multi-mode or single-mode transceivers, so the switch can hold a ring pair and two more fiber runs at once. Switching is store-and-forward on a 40 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-2004G-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-2004G-SFP is the same switch rated -10 °C to 65 °C, the LNP-1802G-SFP has two SFP slots instead of four, and the LNX-2004G-SFP keeps the 16 plus four layout without PoE.
