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-L24P4S-A is an advanced balanced PoE 10 Gigabit switch in the Huawei S5735 series. Its core advantage is "high-performance advanced PoE networking for small and medium-sized scenarios"—24 Gigabit PoE ports adapt to 1200-2800 terminals, with a maximum power supply of 30W per port and a total power budget of ≥510W; 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 functions such as VRRP, stacking enhancement, and intelligent PoE management. It has built-in 6KV surge protection and hardware-level redundancy design, with an annual failure rate of <0.05%, making it the first choice for small and medium-sized enterprises that pursue reliability and scalability.
S5735-L24P4S-A FAQ
Q1: What are the key differences between this model and the basic S5735-L24P4X-A in the same series?
A1: The former is the advanced model, adding features such as VRRP, stacking enhancement, and intelligent PoE management, resulting in higher hardware reliability and suitability for scenarios requiring stability and scalability. The basic model focuses on cost-effectiveness and lacks advanced expansion features.
Q2: Can it simultaneously drive 24 high-power PoE devices?
A2: Yes, with a total power budget ≥ 510W, and with intelligent power allocation technology, it can simultaneously drive 24 20W devices or 17 30W high-power devices, adapting to high-density, high-power PoE scenarios.
Q3: Are the advanced features necessary for small and medium-sized enterprises?
A3: For applications requiring dual-link backup (to avoid network outages), centralized management of multiple devices (stacking), and precise traffic control (such as office/monitoring partitions), the advanced features can significantly improve network stability and operational efficiency, resulting in lower long-term overall costs.
