End of Life product

The EDS-P308 Series is being discontinued due to the switching chip and several key components are going to be phased out. We recommend customers use the 6-port unmanaged Ethernet switch EDS-P206A-4PoE+ with 4 IEEE 802.3af/at PoE+ ports or the 4+2G-port Gigabit PoE+ managed Ethernet switch EDS-P506E-4PoE2GTXSFP with 4 IEEE 802.3af/at PoE+ ports for 4 PoE ports switch applications.

The EDS-P308 switches are smart, 8-port, unmanaged Ethernet switches supporting PoE (Power-over-Ethernet) on ports 1 to 4. The switches are classified as power source equipment (PSE), and when used in this way, the EDS-P308 switches enable centralization of the power supply and provide up to 15.4 watts of power per port. The switches can be used to power IEEE 802.3af compliant powered devices (PD), eliminating the need for additional wiring, and support IEEE 802.3/802.3u/802.3x with 10/100M, full/half-duplex, MDI/MDI-X auto-sensing to provide an economical solution for your industrial Ethernet network. In addition, the built-in relay warning function alerts network engineers when power failures or port breaks occur.
