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-QA1 is a high-performance, cost-effective entry-level 10 Gigabit switch in the Huawei S5735 series. Its core advantage is "economical and efficient 10 Gigabit networking for small and medium-sized scenarios"—24 Gigabit Ethernet ports adapt to 800-2000 terminals, 4 10 Gigabit optical 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 25% 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-QA1 FAQ
Q1: What are the core differences between this switch and the S5735-S24T4X in the same series?
A1: Both have the same core interface configuration. The differences lie in hardware details and some entry-level optimizations. The former focuses more on high cost-effectiveness and the basic needs of small and medium-sized enterprises, without complex expansion functions, resulting in lower costs. It is the preferred choice for budget-sensitive scenarios.
Q2: Can this switch support future terminal expansion?
A2: Yes, it supports it. The 24 Ethernet ports have a 20% redundancy. 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 reconstruction of the existing network, reducing upgrade costs.
