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-L24P4S-A is a high-performance, cost-effective, balanced PoE 10 Gigabit switch from the Huawei S5735S series. Its core advantage is "economical and efficient PoE networking for small and medium-sized scenarios"—24 Gigabit PoE ports adapt to 1200-2500 terminals, with a maximum power supply of 30W per port and a total power budget of ≥510W, capable of simultaneously driving 24 high-power PoE devices; 4 10 Gigabit optical ports support high-speed uplink, with a total switching capacity of ≥598Gbps and a forwarding performance of 96Mpps; it supports basic full functions such as ACL, QoS, and STP, and its procurement cost is 20% lower than that of a standard switch with the same configuration. It is the core choice for small and medium-sized enterprises and campus access layers to "balance power supply, performance, and cost".
S5735S-L24P4S-A FAQ
Q1: What are the core differences between this and the S5735S-L24P4X-A in the same series?
A1: Both have the same core performance. The difference lies in the optical port details and some hardware optimizations. The former focuses more on the basic balanced PoE needs of small to medium-sized scenarios, offering higher cost-effectiveness. It is the preferred choice for scenarios without special expansion requirements.
Q2: Can it drive 24 high-power PoE devices simultaneously?
A2: Yes, with a total power budget ≥ 510W, it can simultaneously drive 24 20W cameras or 17 30W high-power APs, meeting the high-density power supply needs of most small to medium-sized scenarios.
Q3: Is it compatible with non-Huawei PoE devices and older 100Mbps devices?
A3: Fully compatible with IEEE 802.3af/at/bt standards, adapting to PoE devices from different brands; it also supports 10/100/1000M rate auto-adaptation, allowing older 100Mbps devices to be seamlessly connected without additional converters.
