Which of the following answers refers to a dedicated device designed for supplying power over Ethernet cabling?
The answer that refers to a dedicated device designed for supplying power over Ethernet cabling is a Power over Ethernet (PoE) injector or PoE switch.
A PoE injector is a device that is used to add power to an Ethernet cable, allowing the cable to provide both data and power to PoE-enabled devices such as IP cameras, wireless access points, and VoIP phones. The injector typically has two Ethernet ports: one for connecting to an Ethernet switch or router, and the other for connecting to the PoE-enabled device. It injects power into the Ethernet cable to deliver power to the device.
On the other hand, a PoE switch is a network switch that has built-in PoE capabilities. It can supply power to multiple PoE-enabled devices without the need for additional injectors. The switch provides both data connectivity and power to the connected devices through its Ethernet ports.
Both PoE injectors and PoE switches play important roles in delivering power over Ethernet cabling, allowing for greater flexibility and convenience in network deployment, particularly in situations where power outlets are not easily accessible.
