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 S5732-H24UM2CC is a high-performance, balanced 25G switch in the Huawei S5732 series. Its core advantage is "high-bandwidth, high-efficiency networking for small and medium-sized scenarios"—24 gigabit Ethernet ports adapt to 2000-4000 terminals, 4 25G optical ports support ultra-high-speed uplink, with a total switching capacity of ≥598Gbps and a forwarding performance of 280Mpps. It is equipped with an enhanced forwarding chip and a large-capacity cache, supports enterprise-level functions such as link aggregation, VRRP redundancy, and refined QoS, and has a built-in 9KV surge protection design with an annual failure rate of <0.03%. It is the first choice for small and medium-sized enterprises to balance port density, bandwidth, and cost in the core layer and campus aggregation layer.
S5732-H24UM2CC FAQ
Q1: What are the key differences between this and the 48-port S5732-H48UM2CC in the same series?
A1: The former is a 24-port balanced model, with port density suitable for small to medium-sized scenarios, offering better cost-effectiveness; the latter is a 48-port high-density model, suitable for medium to large-scale high-density access scenarios. Both have the same core performance and 25G uplink capability.
Q2: Will there be lag when 24 ports are connected to high-concurrency devices simultaneously?
A2: No. With a total switching capacity ≥598Gbps and forwarding performance reaching 280Mpps, coupled with a large-capacity cache and enhanced forwarding chip, it can easily handle 4000 concurrent terminal transmissions without lag or packet loss.
Q3: Is a 25G uplink switch necessary for small and medium-sized enterprises?
A3: If supporting cloud services, high-definition video conferencing, and high-speed large file transmission is required, a 25G uplink can reserve 3-5 years of business growth space, avoiding frequent upgrades and offering better long-term overall cost.
