Visually the ETMY HWWD looks nominal, all power LEDs are green. To test I unplugged the top monitor connector and after a few seconds the LED-FAULT red led lit up. After 8 seconds I plugged the monitor connector back in which cleared the LED-FAULT light.
Attached trend shows the HWWD STAT go to 8 (led current fault) and the countdown timer started counting down from 20 minutes (seconds channel shown).
It appears there is no problem with the HWWD unit itself, and the change in behavior since the power outage must be related to something upstream (satellite amps). I'll pass this onto Fil for further testing.
At this point I'm not sure if the ETMY hardware watchdog system is fully functional, but bear in mind this is a secondary watchdog to the IOP SWWD.
To show how ETMY HWWD has changed since the power outage, the attached 7 day trend shows its noisy behavior up until the power outage 18:05 Sun 06apr2025 and its zero noise state since. Yesterday's test shows up at the -20hr mark.
