The following Huawei CloudEngine S5755-H models share a similar hardware platform but differ in PoE capabilities and deployment requirements.

Which model should you choose?

• Choose S5755-H24T4Y2CZ if connected devices do not require PoE power.

• Choose S5755-H24P4Y2CZ if standard PoE+ power is sufficient.

• Choose S5755-H24U4Y2CZ if your network requires higher-power PoE++ devices, such as compatible advanced wireless access points.

The Huawei S5755-H24U4Y2CZ is a CloudEngine S5755-H series managed Gigabit Ethernet switch featuring 24 PoE++ Ethernet ports, four 1/10/25GE SFP28 uplink ports and two 40/100GE QSFP28 ports. It is designed for enterprise campus networks and high-performance access applications.

Yes. This model supports PoE++ and can provide up to 60W per port, subject to the installed power supply and total available PoE budget.

The main difference is the PoE capability. The H24P4Y2CZ supports PoE+, while the H24U4Y2CZ supports higher-power PoE++. Both models have 24 Gigabit Ethernet ports, four 25GE SFP28 ports and two 100GE QSFP28 ports.

Yes. Its 25GE and 100GE uplink interfaces make it suitable for aggregation deployments in enterprise campus networks, depending on the network architecture and required traffic capacity.

Yes. The CloudEngine S5755-H series supports VXLAN Layer 2 and Layer 3 gateways, centralized and distributed gateways, and BGP-EVPN.

The power modules are configuration-dependent. The model can use compatible pluggable PoE AC/DC power modules. Buyers should confirm whether power supplies are included in the quotation.

The SFP28 and QSFP28 interfaces support compatible optical connectivity options. Actual transceiver compatibility depends on the optical module specifications, coding, transmission distance and device software version. Confirm compatibility before purchasing third-party optics.

Warranty terms depend on the seller's sales agreement and product condition. Before purchasing, confirm the warranty period, hardware testing, product serial number, delivery condition and return policy.

Yes. Buyers can provide their existing network equipment models, required optical transmission distances, PoE power requirements and deployment environment to help verify the appropriate switch configuration.

When selecting an enterprise PoE++ switch, buyers should consider port density, uplink bandwidth, power capacity and network reliability.

The Huawei CloudEngine S5755-H24U4Y2CZ combines 24-port Gigabit PoE++ access with 25GE and 100GE uplink connectivity. It is particularly suitable for enterprises that need to connect high-power network devices while maintaining sufficient bandwidth for future network expansion.
