A Service Action notice has been posted in the Announcement forum to prevent ReadyNAS NV and NV+ systems from premature power supply failures at viewtopic.php?t=10259. If you own a NV or NV+ within the serial number range in the notice, please either download and install the add-on or perform the simple fan reversal procedure. We've seen a small percentage of our customers experiencing power supply failure and we want to avoid any downtime you may encounter due to an unnecessary RMA process.

If we don't care about the unit noise, is there a preferred solution between the fan reversal and the add on?

ggemelos wrote:If we don't care about the unit noise, is there a preferred solution between the fan reversal and the add on?We find the fan reversal solution to provide better cooling for the PSU. If you are adept at doing the fan reversal procedure, I would recommend that.

I checked and my serial number does not appear to be in the range. I did, however, recently replace my NV power supply with the fanless one.A few questions...Do I need to do anything?Can the power supply temperature be checked via FrontView?If the fan is reversed, won't it then be drawing dust directly in through the back, blowing it across the drives, and then depositing it on the back of the dust screen on the front grille?I was going to open a support ticket but never received the registration confirmation e-mail (tried two e-mail addresses). Thanks.

I did, however, recently replace my NV power supply with the fanless one.A few questions...Do I need to do anything?Yes, since you've replaced with a fanless PSU, you should either install the add-on or reverse the fan.Can the power supply temperature be checked via FrontView?Unfortunately we don't have a sensor there.If the fan is reversed, won't it then be drawing dust directly in through the back, blowing it across the drives, and then depositing it on the back of the dust screen on the front grille?It's possible the dust may collect on the dust screen in the front and you would have to regularly vaccuum it or use an air spray occasionally to clear it -- similar to what you would do to the outside of the mesh when the fan pulling the air into the system. What you can do to avoid this is to remove the dust screen. Just open the door, use a needle or a tweezer to get ahold of the mesh and pull out carefully. This actually helps in lowering the disk temperature more, allowing the fan to operate at lower RPM longer before needing to kick it up due to heat.

After installing via local update and rebooting, I received this message in a pop-up window when I accessed via FrontView...This add-on (Enhance_NV_Thermal_Characteristics) does not apply to this system. [Thu Apr 19 21:25:53 EDT 2007]

Thanks!

You are just before the known range (58552550377 vs. 58552553470 through 58552573952), so you may not be covered. Call the normal support # 888-NETGEAR and see if there's anything they can do. If not, you'll need to buy a new PSU:

Thanks for the info dbott67. I appreciate the responsive community here.

I did some further searching and I'm going the ATX PSU route.

These PSU's fail too often and they sit in a case (NV) that has cooling issues. don't understand why Netgear sells these with NV baseplate attached and charges 3x-4x the going rate for these PSUs.

Thanks Again.

No problem. You may want to call Netgear to see if they can do anything first. Your SN is very close to the known-range and they may be able to take care of the problem.

A minor case of dyslexia may come in handy when reporting your serial number. [just kidding]

I just found out about this issue by way of a burning smell for half an hour, followed by some fierce buzzing and popping noise. YIKES.

So my NV+ no longer turns on, and my serial number's within range (000D-A201-3A03). Do I just need to order a new PSU?

edit: from the thread above, it sounds like I can call in for an RMA — but I'm almost certainly out of warranty. Would this be covered anyway? Fire-related things are scary.

From what I understand, each Netgear regional area determines whether or not it will be covered. I know those folks that live in North America have had the PSU replaced free-of-charge, even if it's out of warranty.

Best bet is to call Netgear support for your area to see what they can do.

Thanks, Dave — haven't got an RMA yet, but things seem hopeful.

I'm also in North America, FWIW.

e: got my RMA. $20 total for shipping? This I can live with.

Here's a question: Will a PSU be shipped out to me before I send in the old one? I'd rather not have any downtime. I'm in Asia but my machine was bought in the US.

That's the deal I got. Had to pay shipping ahead of time, though.

It's probably worth mentioning that disconnecting the battery can bring an early NV back to life.

Did you have it on a timer for on/off ?

If so, then you have run into the problem with the NV where the unit will not respond because there was no power available when the "power-on" command was timed to occur.

Fantastic!

BTW can anyone from Netgear tell me how to call the Hong Kong number? The listed "800 964 605" is NOT a Hong Kong number. I need something with 8 digits.
