OS6 NAS and Riello iDialog 400 UPS
Hello. I have a couple of NAS's, running OS6, and have had a disk failure from a power cut, so I have bought a UPS. i thought that as the current drain is small compared to a server etc, and all i ...

The power connector is on the main board, not the Ethernet daughterboard. I believe it's unlikely that the daughterboard is your issue. A bad power connection could effectively drop the internal voltage due to too much resistance. But there could also be something wrong with one of the internal regulators that drops the voltage for other components.
What specific symptoms are you seeing?
Drives of the generation of when the RNDP2000 was designed actually tended to have higher start-up currents than current, much larger ones. So I doubt the drives are the real cause of your problem, though their load is likely now a factor aggravating the situation.
I have an RNDP2000 that will now only power on properly with one drive installed. I can insert a second once the NAS is up and running, so it is the start-up that's the issue. Even two smaller Red drives, which have low current demands, won't work. Unfortunately, the ReadyNAS does not sequentially start the drives, or it might have lasted longer. It sounds like your unit(s) have the same sort of issue. It comes down to nothing lasts forever -- these NAS are really old in computer years.

Thanks very much. I had no symptoms except the e-mailed warnings about low voltage for a while, then the drives started to spin down and up again, generating ATA errors of course, but when spinning, data were still accessible, then it died completely and wouldn't show any sign of life with no drive or with drives in. I didn't try it with one drive, but if it doesn't even show a power light with none, I think it's dead! This has now happened to three NAS's, all RNDP2000 or RNDU2000, which is odd. Otherwise I found them very fast (with 2GB RAM and OS6) and in other respects rock-solid. I guess I need to move to 312s, although I don't much like the screwdriver-less caddies, which seem flimsy, and sometimes leave the drives behind when they come disconnected on removal!
Thanks again,
Mark

Note you can remove the plastic inserts, and screw the drives into the bottom of the caddies. Your Ultra/Ultra Plus screws will work for this.
Also, your Ultra/Ultra Plus caddies should work in the RN312 NAS (though the new caddies won't work in the old NAS).
