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 S5735-L12P4S-A is an advanced compact PoE 10 Gigabit switch in the Huawei S5735 series. Its core advantage is "high-performance advanced PoE networking for small scenarios"—12 Gigabit PoE ports adapt to 600-1200 terminals, with a maximum power supply of 30W per port and a total power budget of ≥370W; 4 10 Gigabit optical ports support high-speed uplink, with a total switching capacity of ≥598Gbps and a forwarding performance of 96Mpps. Compared to the basic model, it adds advanced features such as intelligent PoE management, enhanced QoS, and link redundancy. Its compact body (approximately 20×15×4cm) is suitable for use in low-voltage boxes, and it has a built-in 6KV surge protection design with an annual failure rate of <0.05%, making it the first choice for small businesses that pursue performance and reliability.
S5735-L12P4S-A FAQ
Q1: What are the key differences between this and the 8-port mini version S5735-L8P4X-IA1 in the same series?
A1: The former is the 12-port advanced model, offering more ports (compatible with more devices) and adding advanced features such as intelligent PoE management and link redundancy, resulting in higher reliability. The latter is the 8-port basic model, focusing on extreme miniaturization and cost-effectiveness, without advanced expansion features.
Q2: Can it simultaneously power 12 high-power PoE devices?
A2: Yes, with a total power budget ≥370W. Combined with intelligent power allocation technology, it can simultaneously power 12 30W high-power APs or 12 25W HD cameras, meeting the power supply needs of all PoE devices in small-scale scenarios.
Q3: Are the advanced features necessary for small businesses?
A3: If you need to monitor PoE device power (to avoid overload), ensure core business bandwidth (such as video conferencing), and prevent network outages (link redundancy), the advanced features can reduce maintenance risks and provide greater peace of mind in the long run.
