are not more received  by their framebuilders(SUSP_Fb and SNEB_Fb) while the data sent by the DaqBoxes are still present.

The ADC7674 SN17 and SN12  boards are VME boards located in the same crate as the VME Mux/Demux one, used to collect the NE suspension data .

One may suspect a trouble with the VMEcrate.

We went a NE and we discovered that both fuses of the VME Crate C79 were burned; we tried to substitute the fuses but they burned again.

We decided to change the VME Crate C79 with a spare one C56.

All the cables were reconnected and Alain from remote reconfigured the ADCs; everything was ok.
