Huawei S1720-28GWR-4X-E-AC Switch – Product Datasheet

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

Product Overview

The Huawei S1720-28GWR-4X-E-AC is a high-performance, enterprise-grade managed Ethernet switch from Huawei’s S1700 series. Designed for small to medium-sized businesses, this switch delivers cost-effective packet switching capability with advanced features suitable for enterprise network access layer deployments.

The switch features 24 x 10/100/1000BASE-T Ethernet ports and 4 x 10GE SFP+ uplink ports, providing flexible connectivity for both copper-based device connections and high-speed fiber-optic uplinks. The 10GE SFP+ ports support a variety of optical modules including GE optical modules, GE-CWDM/DWDM optical modules, GE copper transceivers, 10GE SFP+ optical modules (maximum transmission distance ≤ 10 km), and GPON optical modules.

The S1700 series offers multi-service access capabilities, excellent extensibility, Quality of Service (QoS) guarantee, powerful multicast replication, and carrier-class security. It can be used to build ring topologies of high reliability and is applicable to various scenarios, including Gigabit Ethernet access to enterprise networks and GE-to-desktop deployments, helping build future-oriented IT networks for enterprises.

Key features include:

Hardware-based ACL and MAC address-based packet filtering for enhanced security
4K VLAN support with access, trunk, and hybrid port modes
IPv4 and IPv6 static routing capabilities
Comprehensive security mechanisms: port-based 802.1X authentication, RADIUS authentication, Portal authentication, port isolation, and storm suppression
DHCP Snooping for protection against unauthorized DHCP servers
Web-based network management (HTTPS), SNMP, CLI, and DHCP client support
One-key restoration for simplified recovery

The switch is powered by a fixed AC power supply (100V–240V AC, 50/60Hz) and features natural heat dissipation. With a Mean Time Between Failures (MTBF) of 45 years and a Mean Time To Repair (MTTR) of just 2 hours, the S1720-28GWR-4X-E-AC is built for long-term reliability in demanding network environments.
