A technician is configuring a network switch to supply electrical power to connected devices over standard Ethernet cabling. In this configuration, what is the role of the switch?
Powered Device
Power Sourcing Equipment
Supplicant
Multilayer Device
The switch acts as Power Sourcing Equipment (PSE) because it provides power to the devices over Ethernet cables. The devices that receive power, such as IP phones or wireless access points, are called Powered Devices (PD). A supplicant is a device seeking authentication in network access control (802.1X), and a multilayer device refers to equipment that operates at multiple layers of the OSI model.
