BISv2 Reliability Study Progress Meeting - Global Model 

Present: M. Blaszkiewicz, L. Felsberger, I. Romera Ramirez  

Minutes

The functional block diagram of the entire model was generally accepted as is, with the following adjustments: 

1. CIBFi-Rx cards to be added in BIC 1R, BIC 1L, BIC 5L and 5R.
2. CIBFi-Tx cards to be added to BIC 2R and BIC 8R.
3. All CIBFX cards are supposed to be unmaskable.  

The fault tree discussion spanned several items. The following adjustments are to be added to the model (attached slides are already in the corrected version):

1. The number of CIBUS and CIBUD cards should assume the potential maximal number, which is 17 (20 channels, 3 for optical ones)
2. CIBF and CIBFX cards can take the three channels, which means - there can be 3 cards of those.
3. Only one path of one of the CIBDS OR CIBAB cards has to work for the system to not fail. 
4. CIBG card should also be represented by its two independent paths (assigned 0 FITS).

Next steps

1. Adjustments to the model as discussed.
