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-H48T4S-A is a high-end, high-performance advanced 10 Gigabit switch in the Huawei S5731S series. Its core advantage is "high-density, high-reliability advanced networking for medium and large-scale scenarios"—48 Gigabit Ethernet ports adapt to 4000-8000 terminals, 4 10 Gigabit optical ports support high-speed uplink, with a total switching capacity of ≥958Gbps and a forwarding performance of 420Mpps. It is equipped with a high-end forwarding chip and a large-capacity cache, and adds advanced functions such as enhanced stacking, intelligent traffic scheduling, and dual-link redundancy enhancement. It has a built-in 9KV surge protection + hardware redundancy design, with an annual failure rate of <0.02%, making it the high-end first choice for medium and large-scale enterprises' core layer and campus aggregation layer that "balances high density, high performance, and advanced reliability".
S5731S-H48T4S-A FAQ
Q1: What are the core differences between this and the basic high-end model S5731S-H48T4X-A in the same series?
A1: The former is an advanced model, featuring enhanced stacking, intelligent traffic scheduling, and dual-link redundancy, resulting in higher operational efficiency and reliability. The latter focuses on basic high-end performance, lacking advanced expansion features, and offers better cost-effectiveness.
Q2: Will there be lag when 48 ports are simultaneously connected to high-concurrency devices (such as 4K video conferencing and large data transmission)?
A2: No. With a total switching capacity ≥958Gbps and forwarding performance reaching 420Mpps, combined with large-capacity buffering and intelligent traffic scheduling, it can easily handle 8000 concurrent terminal transmissions without lag or packet loss.
Q3: Is it necessary for medium to large enterprises to choose the advanced high-end switch?
A3: Advanced redundancy features reduce network outage losses for core services, enhanced stacking adapts to future expansion, and intelligent operation and maintenance reduces labor costs. It is suitable for financial, manufacturing, and large office scenarios with high requirements for stability and scalability.
