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-L48T4S-A is a high-performance, high-density 10 Gigabit switch from the Huawei S5735 series. Its core advantage is "economical, efficient, and high-density networking for medium-sized scenarios"—48 Gigabit Ethernet ports can accommodate 2500-4000 terminals, and 4 10 Gigabit optical ports support high-speed uplinks to the core layer, with no idle ports; total switching capacity ≥598Gbps, forwarding performance up to 96Mpps, and support for basic full-featured functions such as ACL, QoS, and STP; built-in 6KV surge protection design, annual failure rate <0.08%, and procurement cost 20% lower than standard switches with the same configuration, making it a core choice for medium-sized enterprises and campuses seeking a "balanced cost, performance, and functionality" for the core layer.
S5735-L48T4S-A FAQ
Q1: What are the core differences between this switch and the S5735-L48T4X-A in the same series?
A1: Both have the same core performance. The difference lies in hardware details and adaptation optimization. The former focuses more on basic high-density 10 Gigabit Ethernet requirements for medium-sized scenarios, offering better cost performance. It is the preferred choice for scenarios without special expansion needs.
Q2: Is this switch compatible with existing non-Huawei core equipment (such as Cisco and H3C) and older 100M equipment?
A2: It is fully compatible with standard Ethernet protocols and 10/100/1000M adaptive speeds, allowing seamless integration with equipment from different brands. Older equipment does not require additional converters.
Q3: Will simultaneous access to all 48 Ethernet ports cause bandwidth congestion?
A3: No, the total switching capacity is ≥598Gbps, with a forwarding performance of 96Mpps. It supports 10 Gigabit link aggregation, and single-link bandwidth can be expanded to 40G, meeting the needs of high-density concurrent terminal transmission.
