Service Action to Prevent PSU Failures in ReadyNAS NV/NV+

Well, it looks like the PSU on my ReadyNAS NV has stopped working. I can't turn the unit on at all. I purchased the unit in August of 2006, don't know if I'm still able to get a replacement PSU or not. Funny thing is this past week is the FIRST time I let the unit run for longer than a day without turning it off. I have never done that before because I always used to turn the unit on as I needed it. Normally, I would only need to power on the unit 2 or 3 times a week to do a quick backup or get some files off of it. Any advice?

It may well be that the constant turning on and off has shortened the life of the PSU. All other things being equal (which they normally aren't but anyway), electronics like this do better if you leave them on all the time. That way there are no big temperature variations. Temperature variations are evil.

Not saying this is the cause. Just saying that the components should be able to run for months and years without interruption. My ReadyNAS is always on, day and night, 24/7/365. The original hard drives had only 10 power cycles when I replaced them after two years. This includes all firmware upgrades and so forth.
