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 S5731S-H24T4X-A is a high-end, high-performance balanced 10 Gigabit switch in the Huawei S5731S series. Its core advantage is "high-reliability, high-bandwidth balanced networking for small and medium-sized scenarios"—24 Gigabit Ethernet ports adapt to 2000-4000 terminals, 4 10 Gigabit optical ports support high-speed uplink, with a total switching capacity of ≥758Gbps and a forwarding performance of 360Mpps. It is equipped with a high-end forwarding chip and a large-capacity cache, supports enterprise-level functions such as link aggregation, VRRP redundancy, and fine-grained QoS, and features built-in 9KV surge protection + hardware redundancy design, with an annual failure rate of <0.02%. It is the first choice for the core layer of small and medium-sized enterprises that pursue quality and cost-effectiveness.
S5731S-H24T4X-A FAQ
Q1: What are the key differences between this and the 48-port S5731S-H48T4X-A in the same series?
A1: The former is a 24-port balanced model, with port density suitable for small to medium-sized scenarios, offering better cost-effectiveness; the latter is a 48-port high-density model, suitable for medium to large-scale high-density access scenarios. Both have the same core performance and high-end hardware configuration.
Q2: Will there be lag when 24 ports are connected to high-concurrency devices simultaneously?
A2: No, with a total switching capacity ≥758Gbps and forwarding performance reaching 360Mpps, coupled with large-capacity buffers and high-end forwarding chips, it can easily handle 4000 concurrent terminal transmissions without lag or packet loss.
Q3: What is the necessity for small and medium-sized enterprises to choose a high-end 10 Gigabit switch?
A3: High-end hardware reduces the risk of network outages for core businesses, high forwarding performance adapts to business growth over the next 3-5 years, hardware redundancy reduces maintenance costs, and it is suitable for core scenarios with high requirements for stability and performance (such as e-commerce and production data transmission).
