S3700-52P-EI-24S-DC – Product Documentation & Specifications

Name: Huawei S3700-52P-EI-24S-DC Switch - SunSpike
SKU: S3700-52P-EI-24S-DC

Product Overview

The Huawei S3700-52P-EI-24S-DC is a next-generation energy-saving Layer 3 Ethernet switch designed for enterprise campus networks, branch offices, and industrial environments. As part of the S3700 series, this 1U high box device leverages Huawei’s Versatile Routing Platform (VRP) software to deliver high-performance access and aggregation capabilities.

This model features a fixed DC power supply, making it particularly suitable for telecom rooms, industrial sites, and environments where stable DC power is preferred. The switch offers a flexible combination of copper and fiber ports, including 24 10/100Base-TX ports, 24 100Base-FX SFP ports, 2 100/1000Base-X SFP ports, and 2 1000Base-X SFP ports. It provides both Layer 2 switching and advanced Layer 3 routing functions, supporting static routes, RIPv1, RIPv2, and ECMP.

Key capabilities include flexible VLAN deployment, comprehensive routing functions, IPv6 migration support, and advanced reliability technologies such as iStack intelligent stacking, VRRP, and RRPP. The switch also features robust QoS/ACL capabilities, multicast management, and energy-saving design with intelligent fan speed control.
