What Are POE Switches Used For

In recent years, PoE power supply technology has been gaining momentum. With a range of advantages such as simplifying the installation and deployment of power-using devices, energy saving, and security, PoE power supply has become a new favourite for scenarios such as wireless coverage, security monitoring, and smart grids.

What is PoE Switch?

PoE switches are switches that support network cable power. PoE switches not only have the transmission functions that ordinary switches have, but can also supply power to the equipment at the other end via the network cable. For the whole network, the use of PoE switches can reduce wiring, lower system costs and higher reliability.

The standard POE switch, which complies with IEEE802.3af, 802.3at standard, is the standard POE switch (commonly known as 48V), the complete POE includes the power supply end equipment (PSE, Power Sourcing Equipment) and the receiving end equipment (PD, Power Device) two parts, poe switch is a kind of PSE equipment. The PD is the terminal device that receives the power (48V national standard devices contain a PD chip).

On the contrary, it is a non-standard POE switch (“non-standard” for short, commonly known as 24V, but non-standard has 48V, 24V, 12V, 5V, etc.).

Advantages of using a POE switch:

  1. Effective time & cost savings

Simplify cabling and save labour costs A single network cable transmits both data and power, PoE makes it possible to save money and time by eliminating the need for expensive power supplies and the time it takes to install them.

  • Safe&Easy

Safe and convenient PoE powered end devices will only supply power to the devices that need it. The Ethernet cable will only have voltage present if the device that needs power is connected, thus eliminating the risk of power leakage on the line. Users can safely mix legacy devices and PoE devices on the network, which can co-exist with the existing Ethernet cable.

3.Easy to manage

Like data transmission, PoE can be supervised and controlled by using the Simple Network Management Protocol (SNMP).
