Huawei S1720-52GFR-PWR-4P-AC – Product Information
Product Overview
The Huawei S1720-52GFR-PWR-4P-AC is a managed Ethernet switch from the S1700 series, designed for deployment at the access layer of enterprise networks. It delivers cost-effective packet switching capabilities while providing multi-service access, excellent extensibility, Quality of Service (QoS) guarantee, powerful multicast replication, and carrier-class security. The switch supports ring topology construction for high reliability and is well-suited for scenarios such as Gigabit Ethernet access to enterprise networks and GE-to-desktop deployments, helping build future-oriented IT networks for enterprises.

The switch features 48 PoE+ 10/100/1000BASE-T downlink ports and 4 Gigabit SFP uplink ports. It is equipped with a built-in AC power module that delivers 370W of PoE power budget, enabling full PoE power on 24 ports compliant with 802.3af or 12 ports compliant with 802.3at. The device includes a mode switching button for toggling port indicator modes (speed, PoE status, and link status), a reset button for factory reset or device restart, and a built-in fan with intelligent speed adjustment for heat dissipation.
