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

I suggest you contact beisser. He would probably know or be able to find out (or direct you to someone who can) what the policy is in Germany.

Where can I buy a RND4PSU1-10000S? I am in HK...

New poster here; purchased the NV+ a number of years ago and have a unit with a Serial # that falls in the PSU Fan Service range (viewtopic.php?p=54911) -- unfortunately my PSU just died (viewtopic.php?f=7&t=70005&p=388412), any ideas where I can get a replacement?

no need to double-post. Try support.netgear.com first.

StephenB -- yea sorry about that, there are two concerns I have that I didn't do a good job clarifying in the other thread:

1. If I can find a replacement PSU somewhere, I'd rather just fix the NV+ myself. Given how huge this thread is and few folks successfully finding replacement PSUs in it, I thought I'd ask about that.

2. In this thread and the other thread, the Service Action item is to reverse the fan and add an addon to your NV+ -- all assuming the NV+ is still running... mine is dead. I haven't seen anyone comment that Netgear is fixing these units or sending out replacement PSUs (and got done reading Netgear support horror stories on Amazon last night) so I'm trying to find a way to fix this myself.

As you pointed out though, I guess I don't have a choice and need to start with netgear support... I am sort of expecting to be back here in 12hrs asking where anyone can find a replacement PSU though -- so I'm trying to get that ball rolling first :(

There are several posters here who have gotten RMAs from Netgear fairly recently who had dead PSUs with units in the affected serial numbers.

Though there is also a recent poster who was told by Netgear that the PSU was unavailable. He was not qualified for the service action however.

There are some threads on how to adapt a stock PSU for the NV+. I haven't tried it, though you might want to search the forums for it.

It appears my ReadyNas NV power supply is on it's last leg. I powered it down after probably a good 2 years without shutting it down and decided to give it a good cleaning job (get the dust out and stuff). I had noticed what sounded like a fan starting to fail so it gave me an opportunity to explore. I initially thought it was the main fan but it ended up being the power supply fan. I took the cover off the power supply to check out the fan and there they were, three bulging, leaking caps! Obviously I bought this unit back in 2006 (Infrant branded) so it's way out of warranty and not included in the power supply service advisory.

My unit is still up and functioning for now, but I was debating if I should go ahead and replace the 3 bad caps and throw in a new fan in the current power supply, or buy a suitable replacement (and make the appropriate wiring changes). If I get the PS back in good shape I'm thinking about throwing in 4 new 2TB drives to give it new life and purpose as my backup unit for my RN314.

Thanks!

The main issue with a third party PSU is that it almost certainly won't fit inside the chassis. So you need to put it outside, unless you can find one of the hard-to-find (and expensive) netgear replacements. Probably no harm in attempting the repair, you can always pick the the third party PSU if it fails.

It is convenient to use older ReadyNAS to back up the main one - I am using a duo v1 and a nv+ v1 to back up my pro-6. I'll retire the duo in favor of the RN102 fairly soon (they are running in parallel now).

My NV's PSU blew (ie, snap crackle, pop multiple capacitors) a week ago. I managed to find an identical Seventeam ST-FUB220-05E PSU. However, when I plugged it in, I got nothing. I noticed though the new PSU's plug wiring was slightly different from mine. Then I found this thread which confirms my suspicions:

So off I go trying to figure out how to pull out some ATX connector pins without the proper tools. It turns out, long header pins (such as https://www.sparkfun.com/products/10158) which you can get easily from your electronics store are perfect. So I used some needle nose pliers to stick two pins into each side of the ATX connector, then a little bit of wiggling, and out comes the connector.

As the above post said, pin 12 and 18 must be +12V. These can be found on the extra 12V connector (it has two black and two yellows, you want the two 12V yellows lines). So I plug the two yellows into pin 12 and 18. Connect the PSU to the NV's board, said a little prayer, and hit the power button. Oh I've never been so happy to see that glowing blue power light!

So anyway, the above is the good news.

The bad news is, as I start to reassemble the NV, I realize the original PSU has one additional difference: cable length. The main ATX connector is approx 12 inch from the PSU. Where as on the otherwise identical new PSU, the connector is only maybe 8" or so. Anyway, so my NV is no longer this pretty thing that's all self contained, but at least I can power it on now and get files off it. I suppose I'll have to figure out some way of improving the aesthetics of it (either by extending the cable, or by making an adapter)

I hope this post helps others as the above post from long ago has helped me.

TL;DR: It is possible to replace the NV's PSU without purchasing the expensive and hard-to-find official part.

I actually purchased the same power supply and modified it like you did. After making the appropriate pin changes (I have a molex tool for that), I modified the cover over the fan to allow the cables to come through over the middle of the power supply.

I first cut the wire ties on the power supply cable bundles (allows it to flatten out), then I removed the bracket on the power supply that covers the fan (has some foam material on it). I bent the top back and forth until it snapped off and then put some tape over the rough edge that is remaining. I re-installed the bracket so that it secures the power supply correctly. The power cable will just barely fit (flatten out the cables). I would suggest plugging in the power supply before mounting the bottom to the RN unit.

It will be just a bit tight but will go together just fine.

PM me if you have any questions or would like any help.
