PHY error

I get PHY Error on the boot loader using serial port
On WinBox I don’t even see the router on the Web Service window.
I’ve read that this could be an ethernet port problem
the thing is that ive got a board with only one ethernet port.

I’ve tried reseting boot configuration and formatting the nand and nothing

Is there a way to recover the board? if its impossible to use poe again at least i want the board to work

Thanks a bunch
Jeronimo

Sorry, but the board is broken.
Send it back and/or get another one.
