I have a ACD with 9.3 cm03 running this past weekend all the but 1 of the power switchs in the Switching cabinets turned off. The contollers did not go down and showed everyhting online. The Switching cabinets had no power on any cards. The circuits had no power surge as these are monitored by are facilities. The Rectifiers in place did not alarm. Are there breakers that possibly are getting weak in the power supply units? If anyone has seen anything like this I would like to hear your story.
Thanks
