TRENDnet's 9-Port Industrial 2.5G DIN-Rail PoE++ Switch with 10G SFP+ Port (24 - 57V), model TI-BG5091B, delivers network connectivity to rugged environments, while saving you on installation costs and setup time using Power over Ethernet technology. The industrial variable voltage switch features a rugged IP50 rated metal enclosure, designed to withstand a high degree of vibration and shock, while operating in both high and low temperatures for industrial environments within -40° - 75° C (-40° - 167° F). This adjustable voltage switch features eight 2.5G PoE++ ports, and a 10G SFP+ port for long-distance fiber networking applications.

Installers and integrators can save on equipment costs and reduce installation time with TRENDnet's voltage booster PoE++ switch by delivering up to 95W per port of PoE power and data over existing Ethernet cables. With PoE technology inside this industrial variable voltage switch, users only need one cable to deliver both data and power. The switch also features Fast PoE technology, which minimizes wait time for PoE devices by providing power immediately at boot up. Dual 24 - 57V DC power inputs on this adjustable voltage switch provide redundancy with power failure alarm relay.
