This cavity has been running since it was recovered on April 7th. There were no visible oscillations until last night around 9. As it is impacting the energy this is most likely somewhere in the probe path. This will take some time to diagnose. We can connect a loop back cable to find out if it's coming from the chassis(receiver channel) as the cavity is already bypassed and this test is noninvasive.

Did not take setpoint, investigation lead to the rack losing communication as detailed in the attached ELOG. Before the rack went down MBC7R06V seemed to have taken setpoint.

Went to investigate mismatch on MBC7R06V, after reseating the card and closing the door saw that the entire rack was reading No Response, and that the LED lights on the front of the utility chassis were not lit. Contacted DC Power on call and they determined the chassis will need to be replaced.
