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 S5736-S48S4X-A is a high-performance enterprise-grade extension switch in the Huawei S5736 series. Its core advantage is "high-reliability integrated networking for medium and large-scale scenarios"—48 Gigabit Ethernet ports meet high-density terminal access, and 4 10 Gigabit optical ports support core layer bandwidth expansion, with a single device covering 1500-3000 terminals; it supports stacking expansion of up to 8 units, with a total switching capacity of ≥598Gbps and a forwarding performance of 96Mpps; it has built-in hardware-level loop protection and flow control functions, with an annual failure rate of <0.1%, making it a core choice for medium and large-scale enterprise campuses, data centers, and branch offices to "ensure business continuity and adapt to business growth" in the core layer.
S5736-S48S4X-A FAQ
Q1: What are the core differences between this switch and the S5736-S48S4X-D in the same series?
A1: Both have the same core performance parameters. The differences lie in hardware details and some expansion compatibility. The former focuses more on the basic core layer needs of medium to large-scale scenarios and offers better cost performance; it is the preferred choice for enterprise campuses and data centers without special customization requirements.
Q2: Can this switch support expansion to over 3000 terminals?
A2: Yes, it can be expanded to 8 devices through stacking technology, supporting a maximum of 6000+ terminal access, while retaining 10 Gigabit optical uplink redundancy, fully meeting the expansion needs of ultra-large-scale scenarios.
Q3: Is it compatible with existing non-Huawei core equipment (such as Cisco core switches)?
A3: Fully compatible with standard Ethernet protocols, supporting seamless integration with core equipment, servers, and terminals from different brands, without requiring reconstruction of the existing network, reducing upgrade costs.

Console port
RJ45
The console port is connected to a console for on-site configuration.
Console cable
ETH management port
RJ45
You can connect a switch to a configuration terminal or network management workstation through the ETH management port to configure the switch locally or remotely.
You can choose to download the software package through the ETH management port in the BootLoad menu. File transfer through the ETH management port is faster than transfer through the console port.
