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-L24T4X-A1 is a high-performance, cost-effective 10 Gigabit switch from the Huawei S5735 series. Its core advantage is "economical, efficient, and precise networking for small and medium-sized scenarios"—24 Gigabit Ethernet ports adapt to 800-2000 terminals, 4 10 Gigabit fiber ports support high-speed uplink, and there are no idle ports; total switching capacity ≥598Gbps, forwarding performance up to 96Mpps, and a web-based graphical management interface lowers the maintenance threshold; annual failure rate <0.1%, and procurement cost is 22% lower than mid-range switches with the same configuration, making it the core choice for small and medium-sized enterprises and small campuses to "balance cost and performance and deploy quickly".
S5735-L24T4X-A1 FAQ
Q1: What are the core differences between this switch and the S5735-L24T4X-D1 in the same series?
A1: Both have the same core performance. The difference lies in hardware details and some adaptation optimizations. The former focuses more on the basic and precise networking needs of small and medium-sized enterprises, offering higher cost-effectiveness and is the preferred choice for scenarios without special expansion requirements.
Q2: Can this switch support future terminal expansion?
A2: Yes, it does. The 24 Ethernet ports have a 20% redundancy reserve. When the number of terminals exceeds 2000, new devices can be added through cascading via the 10 Gigabit optical ports. The existing hardware reuse rate is 100%, meeting 3 years of expansion needs.
Q3: Is it compatible with non-Huawei core equipment (such as Cisco and H3C core switches)?
A3: It is fully compatible with standard Ethernet protocols and can seamlessly interface with core equipment, servers, and terminals from different brands without requiring the reconstruction of the existing network, reducing upgrade costs.
