The Ethernet LED doesn't turn un on the USRP2

Hello All
A while ago my advisor showed how to use the USRP2, yesterday I
connected it to my laptop and the USRP2 booted up (LED D&F came on) but
the Ethernet connection did not respond.

I tried to connect a serial to USB cable to the Debug port and there I
got the correct Rx/Tx Card ID’s and the correct MAC address but when I
connected the Ethernet cable I got

eth link changed: speed 0
and the LEDs on the Ethernet connector stays dark.

The computer that is connected to the USRP2 jumps between “network
connected” and network Disconnected at irregular intervals…

I have tried to debug it using Fireshark -but I couldn’t see any traffic
there.

running “ethtool eth0” I get the following result

Settings for eth0:
Supported ports: [ TP ]

Current message level: 0x00000001 (1)

Any ideas of what can be the issue?
(I have seen that particular USRP2 work earlier so I can’t understand
why it refuses to work now)

Best regards
