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-L24P4X-A1 is a lightweight, precision PoE switch in the Huawei S5735S series. Its core advantage is "easy PoE networking for small scenarios"—24 Gigabit PoE ports adapt to 200-800 terminals, with a maximum power supply of 30W per port, eliminating the need for an additional power adapter; 4 10 Gigabit optical ports support core uplinks; and its compact 1U chassis saves space. The lightweight design allows even non-professionals to deploy it in just one hour, with an annual power consumption of ≤50W. It is the core choice for small and micro enterprises, shops, and small-scale surveillance systems to "reduce cabling costs and simplify maintenance".
S5735S-L24P4X-A1 FAQ
Q1: What are the core differences between this and the S5731S-S24P4X-A?
A1: The former is a lightweight model (emphasizing easy deployment and cost control), while the latter is a standard model (emphasizing expanded functionality). For small-scale scenarios without complex requirements, the former offers better value for money.
Q2: Can PoE power supply meet the needs of high-power devices?
A2: Yes, it supports up to 30W per port (802.3at standard), capable of driving high-power APs and dome cameras. The total power of 400W meets the needs of most small-scale scenarios.
Q3: Is it compatible with non-Huawei PoE devices?
A3: Fully compatible with the IEEE 802.3af/at standard, allowing seamless connection of Hikvision cameras and TP-Link APs without replacing existing equipment.
