TRENDnet's Industrial Fast Ethernet PoE+ DIN-Rail Switches feature a rugged IP30-rated metal enclosure. These industrial unmanaged PoE+ switches are 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). Redundant power inputs with overload current protection on each industrial unmanaged PoE+ switch minimize network downtime. Installers and integrators can save on equipment costs and reduce installation time with TRENDnet's Industrial Fast Ethernet Switches by delivering up to 30W per port of PoE power and data over existing Ethernet cables. With PoE technology, users only need one set of cables to deliver both data and power from the industrial unmanaged PoE+ switch. With these industrial unmanaged PoE+ switches, easily network PoE devices such as high-power wireless access points, PTZ and other advanced IP cameras, VoIP phone systems, IPTV decoders, access controls, and more. PoE+ Power: A 90W PoE+ power budget supplies up to four Power over Ethernet devices with PoE+ power. Fault Tolerance: The industrial Ethernet switch features redundant power inputs. Industrial Hardened Design: Equipped with a rugged IP30-rated housing, designed to withstand a high degree of vibration, shock, and operate within a wide temperature range of -40 - 75°C (-40 - 167°F).
