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 S5735S-L48T4S-A1 is a lightweight enterprise-grade access switch in the Huawei S5735S series. Its core advantage lies in its ability to provide convenient and integrated networking for small and medium-sized enterprises (SMEs). It features 48 Gigabit Ethernet ports for terminal access and 4 10 Gigabit fiber ports for core uplink, eliminating the need for additional equipment. Its lightweight design simplifies deployment, allowing even non-professionals to quickly get started. It supports IEEE 802.3az intelligent energy-saving technology, resulting in 30% lower annual power consumption than ordinary switches. With built-in loop protection and VLAN isolation, it is the ideal choice for SMEs, campuses, and branch offices seeking to balance costs, simplify maintenance, and quickly establish a network.
S5735S-L48T4S-A1 FAQ
Q1: What are the core differences between the Huawei S5735S-L48T4S-A1 and S5731S-S48T4X-A1?
A1: The former is a lightweight model (emphasizing easy deployment and basic access, offering better cost-effectiveness), while the latter is a standard model (emphasizing extended functionality). Small and medium-sized enterprises and branch offices with no complex needs should choose the former, while those requiring advanced management functions should choose the latter.
Q2: Can this switch support future terminal expansion?
A2: Yes, it does. The 48 Ethernet ports reserve 20% redundancy. When the number of terminals increases from 1800 to 2500, new devices can be added via cascading through the 10 Gigabit optical ports, maintaining 100% reuse of existing hardware and meeting 3 years of expansion needs.
Q3: Can existing non-Huawei brand devices (such as Cisco routers and H3C APs) be compatible with the switch?
A3: Fully compatible. It supports standard Ethernet protocols (IEEE 802.3 series) and can seamlessly interface with terminals and network devices from different brands without requiring reconstruction of the existing network, reducing upgrade costs.
