Ahhh have you tried to bring it out of bypass? It’s a bit of a process to do / does risk dropping the load.

Battery wise, you need atleast two good packs to get it going, 4x would be best (one level) From: AF <af-boun...@af.afmug.com <mailto:af-boun...@af.afmug.com> > On Behalf Of Nate Burke Sent: Tuesday, January 03, 2023 12:28 PM To: AnimalFarm Microwave Users Group <af@af.afmug.com <mailto:af@af.afmug.com> > Subject: Re: [AFMUG] Symmetra UPS Questions Yes, we've tried multiple combinations of pulling in/out and the silver on/off screw. We are wondering if its a battery problem because if we pull all battery packs out, it goes to 'no power modules detected'. And when we put the battery packs in, it detects the power modules again and its like the power modules try to start, but the fans cycle on and off.

Also reseat them firmly then turn them on. We had dozens of the 80kw's running here and have been migration the to monster 500KW setups lately. -----Original Message----- From: AF <af-boun...@af.afmug.com <mailto:af-boun...@af.afmug.com> > On Behalf Of Nate Burke Sent: Tuesday, January 03, 2023 12:11 PM To: AnimalFarm Microwave Users Group <af@af.afmug.com <mailto:af@af.afmug.com> > Subject: [AFMUG] Symmetra UPS Questions I have a server room that has a Symmetra PX 20kw that I inherited. On the 25th it reported that 2 of the 3 10kw Power modules went bad. I ordered 2 new 10kw power units, and when i put them in, now all 3 power modules are report 'Off & OK' with a green check mark. They battery system is reporting 'OK' but I'm wondering if the batteries might be causing a problem. Will the power modules not start if the batteries are bad? There is about 9kw of load on the UPS. The battery system says Nominal voltage is 192v, but actual voltage is 154v. When we measure each pack it's at 96v. and 2x96 should be 192, so it must need a minimum of 2 packs to work. -- AF mailing list AF@af.afmug.com <mailto:AF@af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com
