Standard and non-standard POE switches POE switches have what differentiation?

POE china-africa underlying meaning is standard POE power supply, it is compared with the standard POE power supply and speak.

Standard POE for electrical appliances within the POE control chip, he has a test in the power supply before the function, when the device connection, POE for electrical appliances would send a signal to the network, to detect the network IP terminal support POE from electric equipment, if support POE for electrical appliances would give him power supply, if POE is not supported for electrical appliances would not give his power, this is for IP terminal has a protective effect.

Rather than the standard of POE power supply inside this don‘t have the POE control chip, he is directly to electricity by empty lines of 45,78 to the transmission of the cable power supply, he did not test this step, whether IP terminal he will give him support POE power supply, if you don‘t POE power supply IP terminal, is burned so very likely.

But because the underlying work more simple, and don‘t have much technology in it, so the cost is cheaper, also has certain share in the market, but we must be careful to use non-standard POE power supply.

Note:

For electrical standards of POE, not thought that the target IP terminal for the power supply, the underlying POE for appliances can give standard POE terminal power supply
