PoE switch overview

Let me introduce you to the basic concepts of PoE (Power over Ethernet) switches:

Working principle and structure of PoE switch:

  • PoE switch is a switching device that adds power supply function on the basis of ordinary Ethernet switch.
  • It transmits data and power simultaneously through an Ethernet cable to power connected devices, eliminating the need for a separate power supply.
  • PoE switch is mainly composed of three parts: Ethernet switching module, power module and PoE power supply module.
  • The switching module is responsible for data forwarding, and the power module provides the power required for the operation of the switch itself.
  • The PoE power supply module is responsible for detecting, identifying and controlling power supply to the Ethernet line.

How PoE technology realizes the integration of power supply and data transmission:

Power supply method:

  • The PoE switch will inject a DC power supply voltage of about 48V into the idle pairs of the Ethernet cable (the pairs not used for data transmission).
  • Connected devices receive power through these power cord pairs, eliminating the need for separate power cords.

Power supply control:

  • The PoE switch will automatically detect and identify the power supply needs of the connected devices, and implement intelligent power supply management based on the load.
  • Can provide power supply of different power levels to meet equipment with different power supply needs.

Data transfer:

  • Data signals are transmitted through the other two pairs of Ethernet cables without interfering with the power supply.
  • It can realize the integration of power supply and data transmission on the same network cable.

In short, PoE switches realize the unification of power supply and data transmission of network equipment by providing power supply on Ethernet cables, greatly simplifying the complexity of network deployment and maintenance. This technology is popular in application scenarios such as security monitoring and wireless access.
