Hello world, on my brand new RB4011 after not even one day of operation all Ethernet ports are dead - even after factory defaults reset - none of them wants to get up.. after factory defaults reset it does seem to bring whole first line of LED then second line od LED then for some seconds two LED is green where ehternet cables are connected with other devices on it but then the link seems to go down and does not come back 
Anyone had such problem? Did I get a faulty device from a factory?
