H2 SUS FMY Burt Restored
In the previous week's boot fests, it unclear when FMY was taken down, but it had been left in the "empty" state (no matrix elements, no gains, no offsets, etc.). I have BURT restored it to a nominal working state, using
/opt/rtcds/userapps/release/sus/burtfiles/fmy/h2susfmy_safe.snap

Note, after "turn on" (which doesn't really turn anything on), I did my usual sanity checks:
- Is the master switch off and the watchdog tripped? Yes, PASS
- Checked the input and output matrices; do the number's make sense? Yes, PASS
- Checked the OSEMINF banks; are there reasonable offsets and gains? Yes, PASS
- Checked the alignment screens; are speedometers for centered and not going crazy? Yes, PASS
- Checked the BIO screen; are we in State 1, with the monitors indicating our request? NO FAIL

Tried flipping the state around (on both stages, entering in State requests for 0, 1, 2, etc). According to the readbacks (or "monitors") the TOP/M1 stage's low-pass filter is switching appropriately, but the TEST/COIL enable switch does not toggle. The MID/M2 stage shows nothing flipping, which is usually an indication that the coil driver boxes themselves are power down.

Given the stop-work order, this does not surprise me. If we intend to move on and resume work, we should look at these analog drivers to be sure they're ON.
