PoE Switch VS. Ethernet Switch

This video talks about the difference between a PoE switch and an Ethernet switch. So many people might wonder the difference between these two, an Ethernet switch is a device just for basic data exchange, there is not much power needed, so we can easily power up with a 12V DC adaptor. A PoE switch will need to provide PoE signals, so there is a power supply built-in, so we directly connect it with our alternating current. PoE also has an easy plug-and-play feature, no configurations needed, an Ethernet switch might need some settings.
