WTB - ReadyNAS NV power supply

Did you read all the details?
Looking more closely when you click on the 3 available sellers and read the company's descriptions it says "compatible" and there is a picture of something that does not look like the netgear PSU. It also mentions a fan.

I would have checked with the company first before ordering but I see you have ordered already.

I hope it's ok.

Hi, thanks for that - this is the first time I've checked back since my last post, and I returned to update it. I've actually just installed the PSU, put everything back together again and powered on the ReadyNAS - and it *did* power on.
I can see it on my LAN, and access my folders so that's a huge relief - but there is some weirdness.
The quality of these pictures is poor (sorry for that), and I've never used this image host before so I hope they will work. There are two shots of the front LCD:





Both show some... odd characters that have never been displayed before. I've no idea what to make of that, does anyone know what it might mean?

As for the PSU, it came with a cover sheet that says "ReadyNAS NV/NV_ cooling optimisation guidance" which details the fan reversal process (that I think is redundant now - I didn't follow it anyway), but also suggested (because one customer had attempted it with success) cutting a hole in the metal chassis about where the Netgear sticker is on the back of the unit. This is because there is a grill for air flow at that end of the PSU, and with no opening, it backs straight on to the case (so little potential for cooling air to enter there). I don't have the equipment to do proper metal cutting, but I did drill a series of holes in my ReadyNAS case (removing the sticker first - the residue made for a good placement guide!).

The original PSU only has one cable - for powering the ReadyNAS. This unit had several, for lots of peripherals, and that made putting the cover back on a bit difficult (there's not much space for the extra cables). I also ended up with two "spare" screws... no idea where they're missing from (they're distinct from ALL of the other screws that were removed when I took it apart). The original PSU also has a small clear plastic shroud mounded at about the mid-point that runs along the top and down both sides of the unit. The replacement does not have this feature and I'm uncertain as to its purpose.

Otherwise it was pretty straightforward. It's only been on for about half an hour, but so far so good - weird LCD characters apart (I'd like an answer for that, I don't like mysteries when it comes to critical data).

EDIT: also, Frontview shows green lights all 'round.

Hi
I own a ReadyNAS nv+ and its PSU failed about a 10 days ago. There was an associated burning smell that I think is associated with a transformer. The unit has been in service since 2007 with no problems. I went to Amazon and found a PSU compatible. I ordered it expecting a unit that had only the CPU board cable, but this one came with disk power and stuff. I opened the PSU and cut carefully out the extra cables. I also followed the instructions and opened a hole in the back of the PSU case (yes the label had to go) and reversed the fan. Put it all back together and expected it all to work. I have the same problem as you.
The display LCD does not function correctly. It seems to display some characters properly, but then it seems to also insert garbage. Have not looked at it close enough to figure it out. Thought it might be corrupted memory, but the system runs ok. All files are good. Able to access it via network and all looks good there. Did have disk 2 complaining about higher errors, but think it was because PSU was failing. Since you have a similar problem, maybe same problem I have. PSU came from UK, Overtek.
Any help or suggestions from moderator or reader could be helpful. I am an engineer and I have dealt with PSU design in the past.

Ah, that's an interesting co-incidence: yes, mine came from Overtek too. As you say, everything seems to be functioning correctly otherwise... but it's a bit unsettling that this remains unsolved. I haven't restarted the unit since powering it up (or touched the power button to illuminate the LCD), so I don't know whether it would give a repeat performance under those circumstances.
I did wonder whether the extra cables (I didn't cut mine off) might be putting additional pressure on the back of the LCD (I can't remember whether the chassis has a partition between the PSU bay and the rear of the LCD) - you know - that effect you get if you press your fingers against a calculator screen. But I don't suppose it's anything as fanciful as that. Besides, your situation is a little different in that you don't have extra cable jumble bunching up in there, so that pretty much counts that idea out anyway.
