Detailed explanation-1: -PoE switches have significant advantages. Since they cover both power and data, you only need one Ethernet cable for each device. This feature becomes more useful when you have a few power outlets and limited space for cables. With the help of these PoE switches, you can organize the cables.
Detailed explanation-2: -Power over Ethernet (PoE) is a standard that allows Ethernet cables to transmit data and power simultaneously using a single network cable. This allows system integration and network installers to deploy powered devices in locations that lack electrical circuitry.
Detailed explanation-3: -What wire pairs are used for Power over Ethernet (PoE)? An Ethernet cable has eight wires. The blue and white/blue wires (pins 4 and 5) are used for the positive voltage (V+), and the negative voltage (V-) uses white/brown and brown wires (pins 7 & 8 on the RJ45 plug).
Detailed explanation-4: -PoE allows you to power certain devices such as an enterprise grade wireless access point, removing the need for an independent power supply. This reduces the complexity of installing in awkward locations. It is simpler and easier to run one cable than two. That is the rationale behind PoE.
