It has been noted that some ADC channels in the h1alsex model (e.g. H1:ALS-X_LASER_IR_LF) dropped slightly after the h1iscex machine was power cycled due to loss of network connection (cycle was at 11:33 PDT). This was not seen when the h1alsex model was restarted due to crashed epics process at 09:38 PDT. We think that because the computer was power cycled but the IO Chassis remained powered, that this is an unusual startup sequence and perhaps we should perform a full power cycle of both systems.

One hour second trend plot attached.
