Huawei S3700-52P-EI-DC – Product Information

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

Product Overview

The Huawei S3700-52P-EI-DC is a high-performance, energy-efficient Layer 2/Layer 3 fixed-configuration Ethernet switch designed for enterprise campus access or aggregation networks. As an enhanced (“EI”) version of the S3700 series, it supports direct-current (DC) power input, making it particularly suitable for environments where DC power is preferred or required.

Built on Huawei’s Versatile Routing Platform (VRP), the switch delivers robust routing capabilities including static routing, RIPv1, RIPv2, and ECMP. It features intelligent iStack stacking technology, allowing multiple switches to be interconnected via stacking cables to form a virtual chassis architecture with a single management IP, significantly reducing operational and maintenance costs.

The S3700-52P-EI-DC employs a fanless, silent, and energy-saving design that minimizes power consumption, eliminates operational noise, reduces mechanical failure points, and protects against condensation corrosion and dust contamination. Its next-generation high-integration chipset supports idle port sleep mode for further power savings. The switch offers comprehensive QoS, robust security features, multicast optimization, and rapid ring protection protocols, making it a versatile and reliable solution for next-generation campus networks.
