EHG6308-4PoE series switches are Unmanaged PoE Gigabit Ethernet switches. The EHG6308-4PoE switches are 4*10/100/1000BaseT(X) port with Power-over-Ethernet (PoE) and 4 x 10/100/1000BaseT(X) or 4 x 1000baseSFP Fiber. Each PoE port provides 15.4W IEEE 802.3af and up to 30W IEEE 802.3at. Using external 48~57VDC power inputs through terminal block, data and power can be transmitted to  a Powered Device (PD) over the same twisted-pair Ethernet cable through port 1 to port 4 on the unit. The EHG6308-4PoE also provides the relay warning function when power failures.
