What's the Difference between PoE, PoE+, and PoE++ on Huawei Switch? 22 Oct, 2025. Posted by:XPONSHOP

Power over Ethernet (PoE) is a technology that provides power along the 10BASE-T, 100BASE-TX, 1000BASE-T, 2.5GBASE-T, 10GBASE-T, or other Ethernet cables. PoE can effectively provide centralized power for terminals such as IP phones, WLAN Access Points (APs), chargers of portable devices, Point of Sale (POS) machines, cameras, and data collection devices. Terminals are PoE-powered when they access the network; therefore, the indoor cabling of power supply is not required.

A PoE system consists of Power Sourcing Equipment (PSE) and Powered Devices (PDs). A PSE provides power, and a PD receives power from the PSE. As shown in Figure 1-1, the PoE switch functions as a PSE, and terminals such as IP phones, WLAN APs, and cameras are PDs.

 Huawei switches, equipped with PoE, PoE+, and PoE++ capabilities (PoE Switch), provide flexible options for powering various network devices like IP cameras, access points, and VoIP phones. But what exactly distinguishes PoE, PoE+, and PoE++? and how to recognize PoW Switch models?

Involved Network Elements: Powered devices (PDs)

PoE function

· The switch supports power supply capability negotiation using the Link Layer Discovery Protocol (LLDP).
· The switch supports perpetual power supply and fast power-on.
·  If a switch supports PoE, its PoE feature is not affected after it joins a stack.


Licensing Requirements
PoE is a basic feature of a switch and is not under license control.

NOTE: Only switches with "PWR" or "PWH" in the device names are PoE switches. Whether switches support PoE depends on the hardware. Non-PoE switches cannot be changed to PoE switches through software upgrades.
