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 S5735S-L24T4X-A1 is a lightweight precision access switch in the Huawei S5735S series. Its core advantage is "convenient and cost-effective networking for small scenarios"—24 gigabit Ethernet ports adapt to 200-1000 terminals, 4 10-gigabit fiber ports support core uplinks, and there are no idle ports; the 1U compact body saves space, and non-professionals can deploy it in 1.5 hours; it supports intelligent energy-saving technology, with an annual power consumption of ≤45W; and it has built-in loop protection and VLAN isolation core functions, making it a core choice for small and micro enterprises and branch offices to "balance costs and simplify operation and maintenance".
S5735S-L24T4X-A1 FAQ
Q1: What are the key differences between this and the 32-port lightweight version (S5735S-L32ST4X-A1)?
A1: The former is a precise 24-port version (for 200-1000 terminals, saving costs and eliminating waste), while the latter is a versatile 32-port version (for 300-1200 terminals). Small offices/small branch offices should choose the former, while medium-sized and small-scale scenarios should choose the latter for more precise adaptation.
Q2: Can the lightweight version support future terminal expansion?
A2: Yes, the 24 Ethernet ports reserve 20% redundancy. When the number of terminals exceeds 1000, additional devices can be added through cascading via 10 Gigabit optical ports, achieving 100% reuse of existing hardware and meeting 3 years of expansion requirements.
Q3: Is it compatible with non-Huawei devices?
A3: Fully compatible with standard Ethernet protocols, it can seamlessly interface with Cisco, H3C, and other terminals/routers without requiring reconstruction of the existing network.

Long-term operating temperature [°C(°F)]
-5°C to +50°C (23°F to 122°F) (0 m to 1800 m altitude, non-industrial optical modules)
-5°C to +55°C (23°F to 131°F) (0 m to 1800 m altitude, industrial optical modules with transmission distances less than or equal to 10 km)
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 switch cannot be started when the ambient temperature is lower than 0°C (32°F).
The operating temperature ranges from -5°C to +45°C (23°F to 113°F) when optical modules with transmission distances greater than or equal to 70 km are used.
