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 4×10/100/1000BaseT(X). Each PoE port provides 15.4W IEEE 802.3af and up to 30 W IEEE 802.3at. Using external 48 to 57 VDC 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.


  • 8-Port 10/100/1000Mbps Gigabit Ethernet ports
  • Supports P.S.E. based on IEEE802.3af/IEEE 802.3at
