Antaira LNP-2804GN-SFP-T Industrial 28-Port Gigabit Ethernet Switch with PoE+ and Layer 2 Management

Industrial networking tends to move fast and demand flexibility. When many components of a major network are static, you need a few core pieces that are ready to adapt to big demands on the fly. Antaira Technologies builds equipment specifically suited to these tasks.  That has never been more apparent than with the LNP-2804GN-SFP-T. This behemoth switch features 24 Gigabit Power over Ethernet (PoE+) Ethernet ports alongside 4 SFP combination ports. With the 1U rack mount design, it is built to bring powerful, long-range networking when and where you need it.

It’s easy to underestimate the utility of 24 PoE+ ports in a single switch. Each is rated to supply 30 watts per port, enabling you to substantially cut investments on power infrastructure. The LNP-2804GN-SFP-T can be temporarily and rapidly deployed for immediate projects or incorporated into lasting networks. The fully managed switch design enables you to layer precise control over the network options, optimizing security and performance. With so much Gigabit and fiber networking distribution, there are few jobs too demanding for this level of data processing.

Most importantly, this is as tough as switches get. It’s rated for extended operating temperatures (-40° to 75°C) that reach far below freezing and far above surface temperatures on the Earth. It is substantially protected against shock, surge, vibrations and foreign objects. It performs admirably in some of the toughest environments imaginable, and that performance is backed by a 5-year warranty.
