Deep Dive into Key Features
⚡ Layer‑3 Intelligence & Security
Based on Huawei VRP OS, S5735 supports a full range of Layer‑3 protocols—OSPF, IS‑IS, BGP, RIP, VRRP—making it suitable for enterprise campus and data center access layers. Security features include 802.1X, MAC authentication, ACL, DHCP snooping, ARP protection, and DoS defense to safeguard the enterprise edge.
🚀 PoE+ Reliability with Perpetual/ Fast PoE
The S5735-P models offer 802.3at PoE+, delivering up to 30 W per port. Fast PoE ensures PDs (e.g. IP phones, APs) receive power within seconds, and perpetual PoE maintains power to PDs even during switch reboot—critical for VoIP and surveillance systems.
🔁 Reliability & Redundancy
Standard models include redundant power supplies (1+1 PSU). The S5735-S‑V2 has dual PSU support for AC, DC, or mixed supply. Fanless S5735-L‑Q‑V2 ensures silent and energy-efficient operation—perfect for environments like offices or retail.
🧠 Simplified O&M with SVF, EasyDeploy & Telemetry
SVF virtualizes edge switches (including APs) into a logical device for centralized control and plug‑and‑play edge management. EasyDeploy enables zero-touch provisioning and USB-based batch configs. Telemetry via iMaster NCE-CampusInsight provides proactive fault identification and user-experience visibility.
🌐 IPv6‑Ready & Flexible Networking
S5735 fully supports IPv6, including OSPFv3, IS‑IS IPv6, and MLD snooping. Intelligent networking features like SEP, ERPS, GVRP, MUX VLAN, sFlow, and network slicing ensure adaptive, secure, and service-aware operations.
🌟 Fanless Variant for Noise‑Sensitive Environments
The S5735‑L‑Q‑V2 is fully silent, with port dormancy and auto-power adjustments, suitable for healthcare, retail, and conference rooms—while maintaining the same protocol support and security.
Deployment Scenarios & Real‑World Examples
A. High‑Performance 10 Gbps Campus Access
Óbuda University (Hungary) deployed S5735-S-V2 as the access layer for a 10 Gbps campus network, providing high-density multi-terminal support and up to 90 W PoE per port. Coupled with S6730-H-V2 as core, the network achieved non-blocking performance with intelligent O&M via iMaster NCE‑CampusInsight—enabling real-time fault detection and optimization .
B. Quiet and Efficient Office and Retail Access
In corporate office deployments, the fanless S5735‑L‑Q‑V2 serves as an energy-saving and noise-free Enterprise Switch—providing secure 10GE uplinks, PoE+ to badge systems/IP phones, and centralized management—all while blending seamlessly into the environment .
C. Aggregation in Education and SMB Environments
For small to medium campuses, the S5735-S models deliver robust Layer‑3 aggregation and PoE+ for access switches. SVF enables plug‑and‑play / simplified maintenance, while telemetry and EasyDeploy tools dramatically reduce O&M time and cost .
Deployment & Management Experience
- Zero‑Touch Provisioning with EasyDeploy: Plug the switch in, connect USB config file, and deployment completes in minutes; reducing manual labor across floors or data closets.
- Centralized O&M via iMaster NCE‑CampusInsight: Provides topology maps, real-time telemetry, automated root-cause fault detection, and Wi‑Fi optimization.
- Stacking & Scaling with SVF: Aggregates distributed access infrastructure (switches + APs) under logical controllers; ideal for greenfield campus builds.
- Energy & Noise Efficiency: Fanless variants and PoE smart-port dormancy reduce energy use and support silent environments without compromising performance.
- Seamless Firmware Automation: EasyUpgrade supported by HOUP allows one-click upgrades with pre-staging, minimizing network downtime.
