What happens if you send PoE to a non PoE device? This could be a very bad thing.
‌Sending PoE to a non PoE device may cause damage to the device. ‌ Because non PoE devices are not designed to receive power. If PoE power is sent to these devices, it may cause the device to burn or be damaged. ‌
What happens if you send PoE to a non PoE device?

When a device is connected to a standard PoE switch. The switch first checks if the device supports PoE by sending a signal to detect it, before providing any power.
If it supports, it will supply power. If it does not, it will not supply power. This helps protect the device from getting damaged or burned by making sure it can handle PoE before sending power.
However, non-standard PoE switches do not have this detection function. If the switch keeps supplying power even when the device doesn’t support PoE, it could lead to the device getting damaged or burned.

Therefore, you need to pay attention to the following points when using a PoE switch:
▶ First, make sure that the terminal device supports the PoE function.
Secondly, choose a PoE switch that complies with the standard. This can avoid using non-standard PoE switches that do not have detection and identification functions.
Finally, if you need to use a PoE switch with a non-PoE device. It is best to use an active PoE switch and ensure that the non-PoE device does not receive power.
Therefore, if PoE is sent to a non-PoE device, the device will burn or be damaged.
