Marc, Erik, Corey, Betsy, Jim, Dave:

h1seih16 and h1oaf0 were power cycled to recover them from this afternoon's crashes. Sequence is (* applies to h1seih16 only)

  1. stop all models
  2. fence from Dolphin fabric
  3. power down fe computer
  4. * power down AI chassis
  5. power down IO Chassis
  6. power up IO Chassis
  7. power up fe computer
  8. * power up AI chassis

Everything restarted with no issues.

Jim has requested that no watchdogs be untripped on the h1seih16 system. The first DAC (HAM6 ISI+HPI) is still in its DACKILL state because the SWWD is untripped. The second DAC (HAM1 HPI) has zero drive because the h1hpiham1 model is untripped.

Latched IPC and DAQ-CRC errors have been cleared.
