Poe switch 4 connection methods

Many friends who do security monitoring and wireless coverage projects have a lot of knowledge about PoE power supply, and also recognize the benefits of PoE power supply. However, in actual project wiring, PoE has many limitations, such as the upper switch and the lower end. When the terminal equipment does not support PoE, it still adopts the traditional wiring method.

It is well known that traditional wiring methods have high wiring costs and high labor costs and are not conducive to subsequent maintenance. This article discusses several engineering application methods of PoE power supply. After familiarizing with these methods, the convenience of using PoE power supply can be reduced in any scenario.

First, both switches and terminals support PoE

In this way, a PoE switch is directly connected to a wireless AP and a network camera supporting PoE power over a network cable. This method is the simplest, but it also needs to pay attention to the following two points:

1. Determine if a PoE switch and wireless AP or network camera are standard PoE devices

2. Carefully confirm the specifications of the purchased network cable. The quality of the network cable is critical. A poor quality network cable can cause the AP or IPC to fail power or restart.

Second, the switch supports PoE, and the terminal does not support PoE.

The PoE switch of this scheme comes out of the PoE splitter. The PoE splitter separates the power into data signals and power. There are two output lines, one is the power output line and the other is the network data signal output line, which is the ordinary network cable. The power output is 5V/9/12V, etc. It can match non-PoE power receiving terminals of various DC inputs and supports IEEE

802.3af/802.3at standard. The data signal output line, that is, the ordinary network cable, is directly connected to the network port of the non-PoE power receiving terminal.

Third, the switch does not support PoE, the terminal supports PoE

This solution switches out to the PoE power supply. The PoE power supply applies power to the network cable and transmits it to the terminal. This scheme facilitates the expansion of the original cabling network and has no impact on the existing network. Fourth, the switch does not support PoE, the terminal does not support PoE

This solution switches out to the PoE power supply, then to the PoE splitter and finally to the terminal.

Scenario 3 and Scenario 4 are suitable for the transformation of a traditional network, that is, where the original switch does not support PoE power supply but wants to use the advantages of PoE power supply.

Fourth, the switch does not support PoE, the terminal does not support PoE
