To prevent false detection, you should disable PoE on the ports on the PoE switches 
that are used to connect to PSEs.   You should also first power up a PSE device 
before connecting it to a PoE device. When a device is being falsely detected as a 
PD, you should disconnect the device...

The administrator configures all ports to allocate up to 30 watts. This results in 48 
times 30 ports equaling 1440 watts, which is too much. The device cannot provide 
enough power to each port, so it provides power according to the priority.
The administrator sets the priority for each port, allocating how much power it can 
be given.
These priorities...
