Deep Dive into Key Features
⚙️ Layer‑3 Intelligence & Security
Powered by Huawei’s VRP, the S5735S supports robust routing (OSPF, BGP, RIP, VRRP), and features like ACL, 802.1X, DHCP snooping, ARP protection, DoS mitigation, and MAC filtering for enterprise-grade security at the access layer.
⚡ PoE+ with Fast & Perpetual Power
PoE models support 802.3at PoE+, delivering 30 W per port, while Fast PoE powers devices quickly and Perpetual PoE ensures uninterrupted power during firmware updates—ideal for VoIP phones and cameras.
🌱 SVF and Zero‑Touch Deployment
CloudEngine SVF transforms S5735S switches into plug‑and‑play clients in a virtual fabric. Using EasyDeploy, multiple units can be staged via USB or network templates—saving weeks per deployment cycle.
📈 Intelligent O&M & Telemetry
Integrated telemetry and sampling (sFlow) feed into iMaster NCE-CampusInsight for proactive alarms, user experience tracking, and root-cause analysis—cutting troubleshooting from hours to minutes.
🔁 Resilience & Redundancy
1+1 power supply redundancy and stacking via electrical links using iStack ensure high availability. SEP, ERPS, and Ethernet OAM further safeguard uptime and link resilience.
🌐 IPv6 & Flexible Networking
Full dual-stack IPv6 support—RIPng, OSPFv3, IS-ISv6—and VLAN features like GVRP, MUX VLAN, and VBST ensure adaptable and scalable network design.
🤫 Fanless Design Option
The S5735S-L fanless model delivers quiet, low-power gigabit access—perfect for offices, retail, or healthcare, without sacrificing performance or security.
Deployment Scenarios & Real‑World Case
A. Gigabit Campus Access at Óbuda University
In a Wi-Fi 7 rollout, Óbuda University implemented 10GbE uplinks with S5735S-S24P4X at access points. The deployment included SVF and telemetry, enabling unified wired-wireless management, rapid fault localization, and user bandwidth up to 4.5 Gbps for streaming and labs.
B. Quiet Office Access (Fanless S5735S-L)
In an administrative office with low noise tolerance, the fanless S5735S-L provided gigabit access along with VLANs for IP phones and badge readers. Telemetry enabled anomaly detection with near-zero footprint.
C. University Aggregation for Video Surveillance
The S5735S-S48P4X model supported high-density PoE+ for camera arrays and uplinked to higher-tier aggregation switches. SEP and redundancy ensured failover protection in ring topologies.
Deployment & Management Experience
- Zero‑Touch Provisioning: USB or network script-based deployment via EasyDeploy completed campus staging in hours not days.
- Centralized O&M: iMaster NCE-CampusInsight delivers topology visualization, alarm correlation, and performance dashboards.
- Logical Stacking with SVF: Aggregates dozens of switches into one management entity, reducing configuration overhead.
- 24/7 Quiet Operation: S5735S-L models run silently, drawing minimal power—ideal for noise-sensitive sites.
- Automated Upgrades: Firmware can be pre-staged via HOUP, enabling non-disruptive upgrades during maintenance windows.
