Huawei CloudEngine S5755-H48UN4Y2CZ switch Ethernet managed - 48 porte - 10/100/1000/2500 Base-T - 4 x 10GE SFP+ uplink - rackmount

The Huawei CloudEngine S5755-H48UN4Y2CZ is a high-performance managed Ethernet switch designed for enterprise campus networks. It offers 48 downlink ports supporting 100M/1G/2.5G Base-T and 4 uplink 10GE SFP+ ports, delivering a switching capacity of 640 Gbps (up to 1.28 Tbps with stacking) and forwarding performance of 288 Mpps. This 1U rackmount switch supports advanced features such as iStack stacking, comprehensive routing protocols, and robust security mechanisms, making it ideal for access or aggregation layer deployments.

Advantages

High-density 2.5G downlink ports provide future-proof connectivity for Wi-Fi 6 access points and high-performance endpoints. The switch supports dual hot-swappable power supplies and fans for high availability. Intelligent stacking (iStack) simplifies management and scales capacity. Advanced QoS with 8 queues per port ensures smooth traffic prioritization.

Suitable for

• Enterprise campus networks requiring high-speed access
• Aggregation layer in medium to large networks
• Deployments with Wi-Fi 6/6E access points
• Environments needing redundant power and cooling
