I took the slot 0 and last slot card from the portable Fastbus crate we tested in the EEL and put them in ROC4. When I tried before that, I got arbitration errors, so most likely the boards need to have their fuses replaced and checked. After that SFI would try to read the board but had a read block error. I swapped with the last SFI from the BigBite weldment and it worked fine. So I think the SFI of ROC4 is bad, I will get it surveyed and we will check it outside more. I tried the SFI from ROC3 and ROC5 both passed the test_1877 with one TDC in slot 21, so it seems only one SFI is bad so far on the left arm.
I will put back the SFI in place and we will try again when the addressing boards will be fixed in their respective crates.
