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 S series fixed Ethernet switches are available in a variety of models for you to choose based on your network requirements.
CloudEngine S5731-S series switches are next-generation standard gigabit switches that provide GE electrical downlink ports and 10GE uplink ports. The CloudEngine S5731-S series switches were developed based on next-generation high-performing hardware and the Huawei Versatile Routing Platform (VRP). The CloudEngine S5731-S supports simplified operations and maintenance (O&M), intelligent stack (iStack), flexible Ethernet networking. It also provides enhanced Layer 3 features and mature IPv6 features. The CloudEngine S5731-S can be used in various scenarios. For example, it can be used as an access or aggregation switch on a campus network or as an access switch for Metropolitan Area Network.
The Huawei S5731S-S48T4X-A1 is a high-performance, cost-effective enterprise-grade access switch in the Huawei S5731S series. Its core advantage lies in its integrated networking capabilities for small and medium-sized mixed interfaces—48 Gigabit Ethernet ports meet the needs of PCs, monitoring devices, and other terminals, while 4 10 Gigabit fiber ports support core uplinks, allowing a single device to cover 500-2000 terminals. It supports IEEE 802.3az intelligent energy-saving technology, with annual power consumption 30% lower than ordinary switches. Built-in loop protection and VLAN isolation functions ensure stable data transmission, making it a core choice for small and medium-sized enterprises, campuses, and branch offices seeking to balance cost and performance while simplifying access layer deployment.
S5731S-S48T4X-A1 FAQ
Q1: What are the core differences between the Huawei S5731S-S48T4X-A1 and S5731S-S48S4X-A1?
A1: Both have the same core configuration (48 Gigabit Ethernet ports + 4 10 Gigabit fiber ports). The difference lies in hardware technology and some expansion functions. The former focuses more on basic access needs and offers better cost-effectiveness. Choose the former if you don't have special expansion needs, and choose the latter if you need advanced management functions.
Q2: Can this switch support future terminal expansion?
A2: Yes, it does. The 48 Ethernet ports have a 15% redundancy. When the number of terminals increases from 2000 to 3000, new switches can be added via cascading through the 10 Gigabit fiber ports without replacing existing equipment. The hardware reuse rate is 100%, meeting 3 years of expansion needs.
Q3: Is it compatible with existing non-Huawei brand equipment (such as Cisco routers and H3C APs)?
A3: Fully compatible, supports standard Ethernet protocols (IEEE 802.3 series), and can seamlessly interface with different brands of terminals and network devices without the need to reconstruct the existing network, reducing upgrade costs.

USB port
USB 2.0 Type A
The USB port can have a USB flash drive connected to upgrade the switch, or transfer configuration files or other files. The USB port can only connect to a USB flash drive that complies with USB 2.0.
USB flash drives from different vendors differ in model compatibility and drivers. If a USB flash drive cannot be used, try to replace it with another one from a mainstream vendor. Switches support a maximum of 128 GB USB flash drives.
USB flash drive
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.
