Chapter 6 Basic Setting
The Switch supports both the IEEE 802.3af Power over Ethernet (PoE) and IEEE 802.3at High Power
over Ethernet (PoE) standards. The Switch is Power Sourcing Equipment (PSE) because it provides
a source of power via its Ethernet ports, and each device that receives power through an Ethernet
port is a Powered Device (PD).
In the figure below, the IP camera and IP phone get their power directly from the Switch. Aside
from minimizing the need for cables and wires, PoE removes the hassle of trying to find a nearby
electric outlet to power up devices.

You can also set priorities so that the Switch is able to reserve and allocate power to certain PDs.
Note: The PoE devices that supply or receive power and their connected Ethernet cables
must all be completely indoors.
