Q1 - Sorry, I haven't got a clue what you are referring to, more description required, what does the white panel have on it, and what do the red switches have written on/next to them?
Q2 - My QRH, point 4 says - Cross check the IRS and FMC ground speed and winds to determine airspeed accuracy if indicated airspeed is questionable. By this it requires me to make required selections on the IRS panel to see what wind and speed are registering on there and cross check them against the FMC to attempt to deduce the unreliable indication.
