If you need to connect PoE devices using a normal (non-PoE) switch, you must insert a PoE injector between the switch and each device. The injector adds power to the Ethernet line and requires a separate power source. PoE switch and regular switch vary in terms of PoE accessibility. A regular Ethernet switch does not provide PoE for supplying. A PoE Switch, also known as Power over Ethernet Switch, is a network device that allows users to power and connect devices such as IP cameras, VoIP phones, and wireless access points. In essence, a PoE Switch can be described as regular switch with added ability of Power over Ethernet which allows. PoE switches are switches with PoE function, which can transmit data while supplying power, while the main role of ordinary switches is to exchange data, and do not have the function of power supply.
