4-Port Gigabit Ethernet PoE+ Industrial Switch with 2 SFP Ports - high-power PoE+ connectivity for harsh industrial environments. The 4-Port Gigabit Ethernet PoE+ Industrial Switch with 2 SFP Ports from Intellinet Network Solutions was designed to give you the network connections and device power you need in places that are less than calm or temperate. With a rugged, IP40-rated metal case it operates reliably and quietly, even in extreme temperatures that range from -40 to 167 degreesF (-40 75℃). In combination with its DIN-rail mounting option and two safe redundant DC power inputs with power failure alarm and plenty of other safety features, this switch is ideal for IoT applications in Industry 4.0 and more. Gigabit Speeds paired with a large Power Budget. Featuring four auto-sensing 10/100/1000 Mbps RJ45 Gigabit Ethernet ports, this unmanaged switch offers plenty of performance for the devices in your network. The switch features a power budget of 120 W and can distribute a full 30 W (per the IEEE 802.3at standard) to every RJ45 port simultaneously. Also, two small form-factor pluggable GBIC module slots (SFP) provide fiber connectivity for greater distances.
