It's new RB or you take it from some installation? What you see on serial output? What PSU you use?

from a installtion the rest i didn t understand

i think is the IC175C chip it contain the phy.

Perhaps the ports are disabled in software.
Connect to the device via serial port and reset the configuration or boot it via Netboot and reflash it.

Try to use the console cable to connect it.
See what message you getting from the RouterBoard.
