The S series fixed Ethernet switches integrate the access and transmission functions to provide reliable access/aggregation and high-quality transmission of services on enterprise networks. The switches are built on an integrated hardware platform, and their hardware system consists of the chassis, power module, fan module, extended cards, and Switch Control Unit (SCU).
The Huawei S5735-L24T4S-A is an advanced balanced 10 Gigabit switch in the Huawei S5735 series. Its core advantage is "high-performance advanced networking for small and medium-sized scenarios"—24 Gigabit Ethernet ports adapt to 1200-2800 terminals, 4 10 Gigabit optical ports support high-speed uplink, with a total switching capacity of ≥598Gbps and a forwarding performance of 96Mpps. Compared with the basic model, it adds advanced features such as VRRP redundancy, stacking enhancement, and intelligent traffic management. It has built-in 6KV surge protection and hardware-level stability design, with an annual failure rate of <0.05%, making it the first choice for the core layer of small and medium-sized enterprises that pursue reliability and scalability.
S5735-L24T4S-A FAQ
Q1: What are the key differences between this model and the basic S5735-L24T4X-A in the same series?
A1: The former is the advanced model, adding features such as VRRP, stacking enhancement, and intelligent traffic management, resulting in higher hardware stability and suitability for the core/aggregation layer. The basic model focuses on cost-effectiveness, lacking advanced expansion features and is suitable for ordinary access scenarios.
Q2: Will there be lag when 24 ports are connected to high-concurrency devices simultaneously?
A2: No, the total switching capacity is ≥598Gbps, supporting 10 Gigabit link aggregation, with a single link bandwidth of up to 40G. Combined with advanced traffic management, it can easily handle high-density concurrent terminal transmission.
Q3: Are the advanced features necessary for small and medium-sized enterprises?
A3: If ensuring uninterrupted core business operations (VRRP), future business expansion (stacking), and precise traffic isolation (advanced QoS) are required, the advanced features can reduce long-term operational risks and offer better overall cost-effectiveness.
