Some models include a long‑range PoE mode that extends PoE+ reach up to about 200 m (656 ft). Alternatively, PoE injectors or PoE passthrough/extender switches can be used to extend the standard 100 m (328 ft) Ethernet reach to roughly 200 m (656 ft). Check specific model capabilities before deployment.
Higher‑capacity models may include multiple Gigabit SFP or SFP/RJ45 combo ports for fiber uplinks and longer links. Smaller gigabit switches typically focus on copper RJ45 ports only — consult the model spec for available uplink ports.
You can use dedicated PoE injectors to add power to a non‑PoE link, or deploy PoE passthrough switches that receive PoE from an upstream source and pass power to multiple edge devices. Choose injectors for single‑device power and passthrough switches when you need to power several devices from a single PoE feed.
Several models advertise a 10 Gbps switching capacity or switching fabric while providing Gigabit Ethernet on their access ports, which gives headroom for multi‑gigabit uplinks or aggregated traffic. For exact throughput and backplane/switching capacity, check the individual model specifications.
Per‑port PoE limits vary by model. Examples include 6.5 W (when using PD port power distribution), 17 W, 25 W, 30 W, and 32.4 W for PoE+ capable ports. Actual per‑port output depends on each model's design and its total PoE power budget.
Available features include Energy Efficient Ethernet (IEEE 802.3az), Green Ethernet power‑saving (disables unused ports or adjusts power by cable length), PD Alive (auto‑reboot for unresponsive PoE devices), and overload/short‑circuit protection to improve reliability.
