Replacement PSU spec for ReadyNASRNDP6310 ("3VDUAL power is out of normal range...")

[MildredF]

We've just started getting the message

"3VDUAL power is out of normal range [expected: 3.30 current: 3.10]."

on our ReadyNAS Pro Business Edition (ReadyNASRNDP6310).

All other health indicators - including all the temperature indicators - appear to be fine.  

There are three fans on the unit: one at the side (running); one large one at the back, top (running); and a smaller one at the back, lower down, probably PSU, which is not running.  The two fans listed on the health status page are showing a decent RPM, so I assume that the PSU one is not monitored.

Searching the forums for this message suggest conflicting answers about what it means; but combined with the fan not going suggests we should replace the PSU.

Is it possible to get the specification we need for a replacement PSU for this model?

Many thanks,

[JennC]

Thanks Jenn - but both of the PSU look like the fan's in the wrong place?

The ReadyNAS has the fan for the PSU sticking out the back, above the mains socket and power switch - both the items referenced have the fan on a different side from the socket/switch.  Would that work?

There's a short AC cable within the NAS.

Incase this is useful for anyone getting this error:

After looking in to sorceing a new/alternative PSU and coming up empty I have put in a ticket with the support desk. It has been suggested that one of the disks may be starting to fail and to try replacing that to see if the error stops.
