I have a customer who has an opt 51, the breakers on the bottom/back of the cabinet trip almost every day. Sometimes you can just reset the breakers and the switch comes back up, other times you have to power off/on the rectifier first before the PBX breakers can be reset. They are saying the rectifier is reading -33VA to -37VA. FYI, the ring generators on both shelfs are not working, they have been replaced,still not working,the PDU has been replaced, (when the PDU was replaced the fans stopped working) could it be the System Monitor Card or something with the Rectifier? They are saying they had a power surge at this building.
Thanks.
Thanks.
