Note from Andy

Hi Brian, Dan,
All Resonance chassis shipped from SLAC did have the Rev-A power distribution board that was improperly fabricated. Only a few Rev ‘-‘ boards were sent to Fermi from JLab or SLAC, and no refurbished rev-A boards were sent to Fermi. If the board has a rev-A marking, it shouldn’t be trusted long term. There are a few options. We can swap boards by shipping boards only, or we can exchange chassis. SLAC is now focusing on filling the LCLS2 installation with repaired chassis, so I am in favor of swapping boards only. You have listed 2 chassis below, but I believe that 4 chassis were sent to FNAL for work separate from 3.9 GHz CM testing. Those serial numbers are:
18038092, 18038093, 18038094, 18038101.
