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 S5731-H24HB4XZ is a high-performance, balanced PoE 10 Gigabit switch in the Huawei S5731 series. Its core advantage is "high-density PoE + high-bandwidth balanced networking in small and medium-sized scenarios"—24 Gigabit PoE ports adapt to 2000-4000 terminals, with a maximum power supply of 30W per port (supporting the 802.3af/at standard), and a total power budget of ≥370W; 4 25G optical ports support ultra-high-speed uplink, with a total switching capacity of ≥880Gbps and a forwarding performance of 420Mpps; it supports enterprise-level functions such as link aggregation, VRRP redundancy, and intelligent PoE power allocation, and has a built-in 9KV surge protection design with an annual failure rate of <0.03%. It is the preferred choice for small and medium-sized enterprises in core layers and medium-to-high-density PoE scenarios that "balance power supply, bandwidth, and cost-effectiveness".

| 100/1000BASE-X hybrid optical-electrical port | SFP |
A 100/1000BASE-X hybrid optical-electrical port can send and receive data at 100 Mbit/s or 1000 Mbit/s. It can provide PoE power through hybrid cable. In V200R023C00 and later versions, 100/1000BASE-X hybrid optical-electrical ports can be configured to work at 2.5 Gbit/s using the port mode 2.5ge command. |
|
| 10GE SFP+ hybrid optical-electrical port | SFP+ |
A 10GE SFP+ hybrid optical-electrical port supports auto-sensing to 1000 Mbit/s. It sends and receives service data at 1000 Mbit/s, 2.5 Gbit/s, or 10 Gbit/s. It can provide PoE power through hybrid cable. In V200R023C00 and later versions, 10GE SFP+ hybrid optical-electrical ports can be configured to work at 2.5 Gbit/s using the port mode 2.5ge command. |

| 10GE SFP+ optical port | SFP+ | A 10GE SFP+ Ethernet optical port supports auto-sensing to 1000 Mbit/s. It sends and receives service data at 1000 Mbit/s or 10 Gbit/s. |
|
| 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. |
Ethernet cable |
| 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. |

When the altitude is 1800–5000 m (5906–16404 ft.), the highest operating temperature reduces by 1°C (1.8°F) every time the altitude increases by 220 m (722 ft.). The device can work for a short period of time when the operating temperature is beyond the normal range, but the following conditions must be met:
If any of the preceding conditions is not met, the device may be damaged or an unknown error may occur. Devices cannot start when the temperature is lower than 0°C (32°F). The maximum transmission distance of an optical module used for short-term operation cannot exceed 10 km. |
