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-H48HB4XZ is a high-performance, high-power PoE 10 Gigabit switch in the Huawei S5731 series. Its core advantage is its integrated high-density PoE + high-bandwidth networking for medium to large-scale scenarios. It features 48 Gigabit PoE ports supporting 4000-8000 terminals, with a maximum power supply of 30W per port (supporting the 802.3af/at standard), and a total power budget of ≥510W. Four 25G optical ports support ultra-high-speed uplinks, with a total switching capacity of ≥1.02Tbps and a forwarding performance of 480Mpps. It supports enterprise-grade functions such as link aggregation, VRRP redundancy, and intelligent PoE power allocation. With a built-in 9KV surge protection design and an annual failure rate of <0.03%, it is the preferred choice for medium to large-scale enterprise core layers and high-density PoE scenarios that balance power supply, bandwidth, and stability.
S5731-H48HB4XZ FAQ
Q1: What are the core differences between this and the high-end model S5731S-H48HB4XZ-A in the same series?
A1: The former is a basic high-performance model with consistent PoE power supply and 25G uplink capabilities, focusing on high cost-effectiveness; the latter upgrades to a high-end chip and has a larger power budget, adapting to ultra-high-end PoE scenarios, and is priced higher.
Q2: Will there be insufficient power supply when 48 PoE devices are connected simultaneously?
A2: No, the total power budget is ≥510W. With intelligent power distribution technology, it can simultaneously drive 48 10W devices, 30 15W devices, or 17 30W devices, meeting most high-density PoE needs.
Q3: Is it necessary for medium to large enterprises to choose a PoE switch with 25G uplink?
A3: Yes, it is necessary. 25G uplink can support more terminals for high-concurrency transmission, avoiding bandwidth bottlenecks, and is compatible with 10G devices. It can be gradually upgraded according to business growth, making the investment more forward-looking.
In V200R023C00 and later versions, ports numbered GE1 to GE8 and GE25 to GE44 can be configured to work at 2.5 Gbit/s using the port mode 2.5ge command.

-5°C to +50°C (23°F to 122°F) at an altitude of 0-1800 m (0-5905.44 ft.)
Restriction on the operating temperature variation rate [°C(°F)]
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:
The operating temperature exceeds 45°C (113°F) for a maximum of 96 consecutive hours in a year.
The total time when the operating temperature exceeds 45°C (113°F) in a year is less than or equal to 360 hours.
The number of times the operating temperature exceeds 45°C (113°F) is less than or equal to 15 in one year.
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.
