Name: Huawei S1720-28GWR-PWR-4TP-E-AC Switch - SunSpike
SKU: S1720-28GWR-PWR-4TP-E-AC

Product Overview

The Huawei S1720-28GWR-PWR-4TP-E-AC is a fully‑managed Gigabit Ethernet access switch from the S1700 series, designed for small to medium‑sized enterprises, campus networks, hotels, schools, and Internet cafes. It delivers wire‑speed Layer 2 switching with 24 10/100/1000BASE‑T ports, 4 Gigabit SFP uplink ports (2 of which are combo ports), and IEEE 802.3at PoE+ support on 8 ports. The switch provides robust security via 802.1X, MAC, and Portal authentication, advanced QoS with 8 queues per port, and comprehensive management through Web, SNMP, and CLI. Its fanless design ensures silent operation, while static routing (IPv4/IPv6), VLANs, and multicast snooping make it a versatile and cost‑effective access solution.
