PSL trip and Restart
At ≈ 21:00UTC the PSL tripped. The cause is TBD. I was able to successfully restart it without incident.
The watchdogs were reset at 21:24UTC
Looking back at power trends the time of the trip was ~ 20:40UTC. It also seems that the cause of the NPRO tripping off was due to work being done around the racks outside of the enclosure immediately prior to.
