SGI EVM Board Ethernet problem.

Since 2 weeks ago I encountered a problem with the Ethernet connection on the SGI EVM Board. I can't assign an ip address to the board when connecting it to the router and I wonder if the problem could be the Ethernet port. 

This is the result of the ip addr command:
root@arago:# ip addr
1: lo: <LOOPBACK, UP, LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
   link/loopback 00:00:00:00:00:00 brb 00:00:00:00:00:00
   inet 127.0.0.1/8 scope host lo
   inet6 ::1/128 scope host
    valid_lft forever preferred_lft forever
2: eth0: <BROADCAST, MULTICAST, UP, LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 42:86:26:84:e9:ef brb ff:ff:ff:ff:ff:ff:ff
    inet6 fe80::4086::26ff::fe84:e9ef/64 scope link tentative dadfailed
      valid_lft forever preferred_lft forever
I tried using the second Ethernet port but the lights on this port are not even blinking. Should both ports work?
Another thing to notice is when I remove the Ethernet cable from the board, the lights are still on even though the cable is not connected. Is this normal?
It worked fine for 3-4 months.
Any help would appreciated.
Regards,

Hugo A Santana.

    Hi Hugo,

    Have you made some changes to the  kernel, or some driver specifics, to generate this kind of  behavior?

    To which Ethernet port are you referring as a second one?

    Hello Boyko,

    I haven´t made any changes on the Kernel. I am using a SOM Board to connect to PLC Kit 3000 modems. Everything was working fine for 4 months, but now I can´t assign an IP address on the SGI EVM Board as I said.

    The Ethernet port that I was using before succesfully is the one with letter R. I also tried with port Q, but Q leds doesnt even light up or blink.

    Here is the diagram:
