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-H48T4X-A is a high-end, high-performance 10 Gigabit switch in the Huawei S5731S series. Its core advantage is reliable networking for medium and large-scale scenarios with high density and high bandwidth. It features 48 Gigabit Ethernet ports supporting 4000-8000 terminals, 4 10 Gigabit optical ports supporting high-speed uplinks, a total switching capacity of ≥958Gbps, and a forwarding performance of 420Mpps. Equipped with a high-end forwarding chip and large-capacity cache, it supports enterprise-level functions such as link aggregation, VRRP redundancy, and refined QoS. With built-in 9KV surge protection and hardware redundancy design, its annual failure rate is <0.02%, making it the top choice for medium and large-scale enterprises' core layer and campus aggregation layer, balancing high density, high performance, and stability.
S5731S-H48T4X-A FAQ
Q1: What are the core differences between this and the S5732-H48S6Q in the same series?
A1: The former is a high-end model with higher forwarding performance and buffer capacity, and a more robust hardware redundancy design, adapting to high-end core layer requirements; the latter focuses on conventional high performance, providing 6 10 Gigabit uplink ports (with stronger redundancy), offering better cost-effectiveness.
Q2: Will there be lag when 48 ports are connected to high-concurrency devices simultaneously?
A2: No, with a total switching capacity ≥958Gbps and forwarding performance reaching 420Mpps, combined with a large-capacity buffer and high-end forwarding chips, it can easily handle 8000 concurrent terminal transmissions without lag or packet loss.
Q3: What is the necessity for medium to large enterprises to choose a high-end 10 Gigabit switch?
A3: High-end hardware reduces the risk of network outages for core services, high forwarding performance adapts to future business growth, and hardware redundancy reduces maintenance costs, making it suitable for core scenarios with high requirements for stability and performance.
