On connect PoE to port1 750GL shutdown

Hi, i have a problem with router 750GL v6.36 (last stable) firmware 3.19, when i connect a utp with PoE to port1 the router automatically shutdown.
I cant get any log either, only 11:42:44 interface,info ether1-gateway link up (speed 100M, full duplex) and them nothing, router shutdown until disconnect the PoE.
I cant find any menu with PoE options.

Any help it is welcome!

Thank you.
