If it blows when everything is unplugged from the ksu and you power up the power supply, and you want to try to repair the system, you'll need to start with a good power supply and see if anything else is bad. Hense the reason I keep one in a crash kit. Mark Reliable Telephone Service

We've used them to power up DX-80s in a pinch. Sometimes it a lot easier to just replace the cabinet, use the same cards (CPU etc) and be done with it---if you think that it's just the power supply. Send PSs to ********* to get repaired. I've sent about 8 to them and have been satisfied with all. Rockford VoIP
