Subject: All vertex SUS watchdogs were tripped 

Yes, this was a consequence of the systemd scripting I was setting up. Unlike the old susaux system, we decided for safety NOT to allow the modbus IOC to automatically enable the coil outputs. Thus when the modbus service starts/restarts, it automatically restores all state except the watchdog channels, which are left in their default disabled state. They then have to be manully enabled by an operator, as I should have done after finishing testing.


I found the 8 vertex watchdogs tripped today morning. The ETMs were fine, suggesting this was not an actual earthquake. I suspect it was connected to this remote work? Was there a reason why they were left tripped?
