4-Port Gigabit Ethernet Switch with 2 SFP Slots

4-Port Gigabit Ethernet Switch with 2 SFP SlotsEN50121-4EN61000

The IGS-402S(-E) is an unmanaged Gigabit Ethernet Switch equipped with 6 Gigabit Ethernet ports and 2x 1000Base-X(SFP slot) fibre optic ports. 4 ports 10/100/1000BaseT(X) support IEEE 802.3/802.3u/802.3x/802.3ab, full/half-duplex, MDI/MDI-X auto-sensing, making them ideal for providing an economical high-bandwidth solution for your industrial Gigabit Ethernet network. Switchable 100Base SFP or 1000Base SFP can be set up easily using the DIP switches located on the Front panel. The IGS-402S(-E) switches built-in relay warning function for alerting power failures; providing broadcast storm protection function to eliminate the broadcast storming in your networks. The switches can be installed easily on a DIN-Rail or Wall mounted, IGS-402S-E wide operating temperature (-40 ~ 75°C) models especially for industrial harsh environment applications.
