GE11-M-31L1-S: VFAT10 Communication Issue
During the recommissioning on May 20-21, 2021 we saw the following evolution of issues:
- GBTs locked on power up (no power cycle needed)
- GBTs stable during GBT phase scan
- VFAT10 and 20 were lost during DAC scan
- Set GBT phases to 15 for VFAT 10 and 20 and took DAC scan without it
