Hi all,
Starting with run 10834, all WFDs were put back in acquisition. There
are no error messages coming from them except 2-3 system errors at
the beginning of each run.
The problem in SM4 was the backplane which we've swapped. All the errors
that appeared in the rest of the SMs went away just by themselves.
Doug has brought three new VIC modules; Maurizio is going to work on fixing
the bad backplane of SM4. It might be useful though to have another
backplane as a spare.
BTW, Nat mentioned that there are two VME extenders. I found just one- any
place where to look at for the second one?
