Two quick things to look into:
- That UHD + GNU Radio versions are very, very old. It should work, but
I recommend upgrading.
- uhd_find_devices and uhd_usrp_probe don't require you to know the
USRP's IP, as long as it's on the same subnet. So try without the
--args. If you're sure about the IP, try ping.

Different revisions (rev 2, rev 3, etc.). Your board revision should be
on the silkscreen, if in doubt. But the revision is also stored in the
EEPROM, and should correctly be detected.

Which problems did you have? Which OS are you using?

You can find the description of the LEDs at
