Huawei S2720‑28TP‑PWR‑EI Full English Product Description
Product Overview
Huawei Quidway S2720‑28TP‑PWR‑EI belongs to S2720‑EI series enhanced managed PoE+ access switch powered by mature VRP operating system. It provides 24×10/100BASE‑TX PoE+ downlink ports, 2×GE SFP uplink ports and 2×Gigabit combo ports (RJ45/SFP). Equipped with built‑in high‑power PoE power supply and temperature‑adjustable fan cooling, it delivers abundant Layer‑2 features, basic Layer‑3 routing, complete security policy suite and iStack stacking capability. It is widely deployed for enterprise campus access, branch office, IP surveillance and wireless AP access scenarios requiring remote PoE power feeding。
