Huawei CloudEngine S5755-H24P4Y2CZ – Product Documentation
Product Overview
The Huawei CloudEngine S5755-H24P4Y2CZ is a high-quality Gigabit access switch from the CloudEngine S5755-H series, designed for next-generation campus networks, especially for the Wi-Fi 6 and Wi-Fi 7 era . This managed Layer 3 switch provides 24 fixed 10/100/1000BASE-T downlink ports with Power over Ethernet Plus (PoE+) capability, along with four 25GE SFP28 and two 100GE QSFP28 high-bandwidth uplink ports .
Built on Huawei’s unified software platform, the switch supports VXLAN-based network virtualization, enabling multi-service convergence on a single physical network to reduce deployment and operational costs . A key distinction of this model is its enhanced PoE+ support with a total power budget of up to 840W, making it an ideal choice for powering WLAN access points, IP cameras, and other networked devices .
The device features a modular power architecture with N+1 power supply redundancy (three hot-swappable power module slots), and its compact 1U form factor makes it suitable for space-constrained wiring closets and data centers . All ports support MACsec encryption for end-to-end security, and the switch supports stacking of up to 9 units via Huawei’s iStack technology .
