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-L8T4S-A1 is a high-performance, cost-effective mini entry-level 10 Gigabit switch in the Huawei S5735 series. Its core advantage is "low-cost, high-efficiency 10 Gigabit networking in micro-scenarios"—8 Gigabit Ethernet ports adapt to 200-800 terminals, and 4 10 Gigabit fiber ports support high-speed uplink or expansion, with no port waste; its mini body (approximately 20×15×4cm) can be directly placed in a weak current box or on a desktop; web-based graphical management allows non-professionals to deploy it in 30 minutes, and the purchase cost is 35% lower than that of a mid-range switch with the same functions. It is the core choice for micro-enterprises, small offices, and branch access to "save costs, save space, and save maintenance".
S5735-L8T4S-A1 FAQ
Q1: What are the core differences between this and the S5735-L8T4X-A1 in the same series?
A1: Both have the same core performance. The differences lie in hardware details and some compatibility optimizations. The former focuses more on basic entry-level networking needs in micro-scenarios, offering higher cost-effectiveness and is the preferred choice for scenarios without special expansion requirements.
Q2: Can the 8 Ethernet ports be expanded if needed?
A2: Yes, they can be expanded by cascading other switches through the 4 10 Gigabit fiber ports, covering up to 1600 terminals. This meets the business growth needs of micro-scenarios for the next 3 years without requiring replacement of existing equipment.
Q3: Is it compatible with older 100Mbps devices (such as old printers and 100Mbps cameras)?
A3: Fully compatible with 10/100/1000M adaptive speeds. Older 100Mbps devices and newer Gigabit devices can be connected simultaneously without the need for additional converters.
