The switch is an unmanaged PoE Ethernet switch with P.S.E. function. The switch supports Power over Ethernet, a system that transmits electrical power along with data to remote devices over standard twisted-pair cable in an Ethernet network. The switch has 8 X 10/100/1000Base-T(X) P.S.E. (Power Sourcing Equipment) ports. P.S.E. is a device (switch or hub for instance) that will provide power in a PoE setup. Moreover, the wide operating temperature range from -40 to 75°C can satisfy most operating environments. The switch is one of the most reliable choices for PoE Ethernet applications.
