▪ Flexible uplinks (SFP/SFP+/10 GbE) facilitate seamless aggregation and uplink architecture integration.
▪ Stack capability (S5735‑L‑V2) simplifies management and improves redundancy in campus networks.
▪ Fan redundancy in S‑series ensures high availability and reliability.

Use Cases and Deployment Scenarios

Access Layer in Campus Networks

Deploy S5735-L in classrooms, office buildings, or branch sites where centralized PoE is needed. Models with 24–48 PoE+ ports provide both data and power without separate injectors.

Aggregation Layer with High Port Density

Use S5735-S to aggregate traffic from multiple access switches. High-density PoE and modular uplinks ensure flexible cabling and future-proofing.

IoT and Intelligent Building Deployment

With robust PoE capabilities, S5735 switches support IP surveillance, access control, intercoms, and environmental sensors—ideal for smart campus and building networks.

Performance and Software Capabilities

Huawei’s CloudEngine S5735 integrates the V600R022C01 or later VRP software—offering full-featured Layer 2/3 switching, dynamic routing (OSPF, RIP, BGP lite), IPv6 support, VRRP, and static routes. Security features include port security, DHCP snooping, ARP inspection, and IP source guard. Intelligent OAM and SR-TE support monitoring, troubleshooting, and simplified operations across campus deployments.

Stacking and Manageability

The S5735-L‑V2 series supports stack deployment, enabling up to nine units to operate under a single management IP, drastically simplifying network expansion and maintenance. Stack management offers unified configuration, VLAN consistency, and efficient firmware upgrades.

Energy Efficiency and Reliability

Huawei emphasizes energy effectiveness in the S5735 line. Intelligent fan control, efficient power supply circuits, and energy-aware design help reduce electricity costs—particularly in high-density PoE deployments. Redundant power modules in S-series boost resilience, while dual-fan airflow design supports stable operation under heavy load.

Comparison of S5735‑L and S5735‑S Series

The CloudEngine S5735‑L series is designed for compact access deployment. It offers built-in PoE power up to 400 W, fixed 10 GbE uplinks, and stacking capabilities in the V2 models. This makes it ideal for branch networks, classrooms, and standard office environments.On the other hand, the CloudEngine S5735‑S is tailored for aggregation or high-density access scenarios. It supports dual modular 1 000 W PoE power, has modular uplinks for flexible configurations, and includes advanced fan designs for reliability. It is better suited for large buildings, campuses, and high-demand PoE applications.

Why Choose CloudEngine S5735 Huawei Switch?
