Huawei S3700-52P-PWR-SI-AC – Product Documentation

Name: Huawei S3700-52P-PWR-SI-AC Switch - SunSpike
SKU: S3700-52P-PWR-SI-AC

Product Overview

The Huawei S3700-52P-PWR-SI-AC is a next-generation Layer 3 Ethernet switch designed for enterprise campus networks, small and medium-sized businesses (SMBs), and PoE-powered device deployments. Part of the S3700-SI series, this managed PoE+ switch delivers reliable power and high-speed connectivity to wireless access points, IP cameras, VoIP phones, and other networked devices.

The switch features 48× 10/100 Mbps Fast Ethernet ports with PoE+ support and 4× Gigabit SFP uplink ports, providing scalable fiber expansion for flexible network growth. It comes with a built-in 500W AC power supply and dual power slots for enhanced power redundancy. With a switching capacity of 64 Gbps and a forwarding performance of 13.2 Mpps, the S3700-52P-PWR-SI-AC delivers enterprise-grade performance for demanding network environments.

The switch supports advanced features including VLANs (4K), QoS, ACLs, STP/RSTP/MSTP, IPv4 and IPv6 routing, multicast, and comprehensive security mechanisms. Reliability is enhanced through technologies such as RRPP (ring protection with <50 ms switchover), Smart Link, and SEP. Designed for 24×7 continuous operation, this rack-mountable switch is ideal for office LANs, campus networks, retail, hospitality, and educational environments.
