PoE port issue -Switch SRW224G4P


I'm working with a switch of the model SRW224G4P  and i noticed one strange behavior in it.

If I start the switch without a PoE device connected to a port and connect one after it initiated the switch doesn’t recognizes device at all.

No power is sent to the device no matter how many times i try to connect/disconnect it.

The only way to provide power is resetting the switch with the device already connected to the port, then no problem the device is reconized and works fine.

If I disconnect the device while the switch is on and connect it again, the same thing happens, with the port not sending the power to it.

I would like to know if there is some configuration that could cause this?

This not happens in a specific port, I tested in more then one, the cables and devices are ok, because they work if i restart the switch.

Any ideas of what could be happening?

Thanks in advance.
