Power over Ethernet (PoE) is the implementation of IEEE 802.3af, IEEE 802.3at, and IEEE 802.3bt (Type 3 and Type 4), which allows for both data and power to pass over a copper Ethernet LAN cable. Typical power devices include wireless Access Points and VoIP telephones.
Depending on the technology and application requirements, PoE is classified into classes. Depending on the power requirements, the PoE devices are categorized by type. Classes range from Class 0 to 8 whereas types range from Type 1 to 4. Each type associates with an IEEE 802.3 PoE standard. These standards provide signaling between the power sourcing equipment (PSE) and the powered device (PD). PSE devices, such as switches, provide power on the network cable. The devices that PSE provides power to are called PDs, such as VoIP phones, wireless access points, and IP surveillance cameras.
To know which ports support PoE, see VSP 4900 Series Switches: Hardware Installation Guide.
The switch uses the Dynamic Power Allocation scheme when supplying power to devices. Only the power being consumed by the device is allocated, improving efficiency and enabling support for more number of devices.
You can configure PoE from CLI and Enterprise Device Manager (EDM).
