- Interesting. We've run 2 7171s for 3 years, and have had only one problem,
- a faulty CPU board.

- It sounds like either your line voltage into the 7171(s) has a problem, or
- perhaps there's a short inside that's drawing too much current. I'd have
- the CE check into that before installing another power supply.
