Uhd + usrp2 warnings

Hi,

If i power on the USRP2 board, LED F light up first and LED E, C, A
flash and LED F and D remains on. Is that the correct boot up sequence
cos i saw in youtube video, LED B, D and F remains on.

If i run GRC i’m seeing following warnings,

Is there something wrong with uhd+gnuradio installation?
