RJ45 ports serve access-layer copper connections; SFP/SFP+ ports enable flexible 1G/10G uplinks; SFP28 delivers 25G for modern data centers; QSFP+ and QSFP28 support high-density 40G/100G spine–leaf fabrics. The EDS-G512E Series is equipped with 12 Gigabit Ethernet ports and up to 4 fiber-optic ports, making it ideal for upgrading an existing network to Gigabit speed or building a new full Gigabit backbone. It also comes with 8 10/100/1000BaseT (X), 802. 3at (PoE+)-compliant Ethernet. A Power Over Ethernet (POE) switch is a network switch that can provide power to devices over the Ethernet cabling itself, eliminating the need for separate power sources. That one fact is why a wireless access point on a ceiling, an IP phone on a desk, or a camera on a wall needs no power outlet next to it: the switch port that carries its traffic also powers it.
