CtrlDPM died after tests to AE100849 were completed. The problematic DPM (dpm3) was switched out using another available board. Old dpm3 is now dpm1, new CtrlDPM is dpm5.


September 20th:

Testing Flange Boards:

Numbering convention is top (0) to bottom (3).

Noticed QSFP housing on Flange0 was a bit tilted, back pins were loose. After adjusting the board a bit and re-powering, were able to see all hybrids. Observed flange current flickering between ~0.2 and 0.4 A on first power-up.
