h1seih16 powered down for ADC error investigation

WP11227

Jim, Erik, Fil, EJ, Dave:

h1seih16 is currently powered down. Erik has found a possible issue with the second Adnaco backplane in the IO Chassis, he is in the process of moving all the cards from the 2nd to the 3rd Adnaco backplanes.

EJ confirmed that a communication issue with the second backplane (which holds A1, A2, A3 and D1) would raise an timing error on A1 but not the other cards.

1 DAC and 3 ADCs were moved from adnaco PCIe expansion board 2 to board 3.  h1seih16 was powered back up and is running.  Board 2 appears to be working again with no IO cards plugged into it.
