D-Link DNS-323 / Anybody?

[Wild Hare]

One of these recently “came to me” without a power cord and I can’t seem to locate a schematic for the 4-pin power input to test. (Before I splurge on buying one only to discover that the unit is “deceased”.)

So, anyone have one of these… use one of these… or know what the power pin-configuration might be? Supposedly, similar 4-pin LaCie power supplys won’t work - and reportedly will fry the device.

And yes, I know the Synolgy NAS are “more better” / faster… but this one was “no cost”. (So far.)

I do not have one, but as long as you can match up the output (of the adapter) you should be good. Ie., 12v 5amp.

That's just an example, I'm not saying your NAS has that spec as I would not know.

You can buy any old adapter that fits and has the right output and sellers know this. So the problem now days is that they blur out these details or obscure them. If you don't know the spec, you have to trust the seller. Makes it so you don't run off to someone who is selling it cheaper.

I'm guessing D-Link didn't stamp the output/input specs on the case?

I have this same problem with my ICY Dock RAID enclosure.

For DC it's not just volts and amps, but also where positive and negative pins are. Getting the polarity wrong may well fry stuff.

Have seen several references to:

“JENTEC JTA0707-Y 5V/4.2A 12V/3A 4 Pin AC Adapter PSU”
as a possible replacement for the original (missing) power supply.
But without an original one to test or a bona fide schematic,
could be an absolute failure and destroy circuity.

Even this arrangement is a gamble without the original.
And no, no specs on the unit itself.

Dlink, anyone ? Not.

 

[Wild Hare]

Thanks for the bump @Macbookprodude. Evidently Not (on the D-Link).
It’s shell shall remain - but the (2) 1TB drives will find new homes.

Dlink, anyone ? Not.

What's wrong with D-Link? I have and have had several of their products and they work just fine.

The manual download page:

The D-Link 2-Bay Network Storage Enclosure (DNS-323)enables you to share documents, files, and digital media such as music, photos, and video with everyone on your home or office network. With the built-in FTP server, you can access your files remotely over the Internet from anywhere in the...

The three that will download say: Power Adapter (12V; 3A, 5V; 3A)

I see a couple of third-party ones on Amazon USA but I'm not sure about returns.

From this iFixit teardown, it looks like the bottom two pins are ground and the top two pins are different voltage rails (almost certainly the 12V and 5V that @BrianBaughn identified).

I don’t know which is which, though, without probing the actual boards with a multimeter and seeing what connects to the SATA 12V and 5V pins.

 

[Wild Hare]

Thanks everybody. Without someone actually having the specific D-Link PSU and being able to state without-a-doubt which pin is 5 volts and which one is 12 volts… well there’s a 50/50 chance of smoke.

I’ve read accounts of some LaCie PSUs being very similar to the pin configuration of the D-Links’ - except legs (and voltage) reversed. And while these other PSUs will “light-up” the D-Link momentarily… smoke then results Not good.

So for now, the 2 drives have been removed and the D-Link project placed on the back burner (as I’m now off to attempt not to smoke… other things).

Thanks!

I struggled with the same problem, and to confirm OP's concerns, a power supply sold on Walmart.com (T-Power brand) that was advertised to be compatible with DNS-323 did destroy the board on my NAS because +5V was wired where +12V rail should be and vice versa. The seller was very apologetic about it and sent me another one on the house, and coincidentally I had already purchased a replacement second hand DNS-323 so I thought why not, but this time I learned my lesson and to my un-surprise the replacement power supply had the same miswiring issue. I reached out to seller, they apologized again, and asked if I were interested in a yet another replacement. I told them that I were only contacting them to let them know that most likely their complete stock was wired incorrectly. Anyway... To enlighten the few who still possess a D-Link DNS-323 (or a similar model with 4-pin DIN power supply) and is in the market for a power supply, the expectation of the board is: If the back of the NAS and the female 4-pin DIN socket is facing you, the bottom pins are ground pins, and they are joined together on the board, so it doesn't matter which is which. The top left pin is +12V rail, and top right is +5V rail, so you must make sure the power supply you procure matches that very configuration. If you are holding the power supply instead, when the male plug is facing you, the top right pin is +12V rail, and top left is +5V. I hope you find this information helpful.

Edit: Both +5V and +12V rails expect 3 Amps each according to the specs of the original unit.

Since there are confusing posts I want to make it clear for everyone. The screenshot I've attached here has the correct voltages. Disregard the Jentec posting by Wild Hare, he was right to call that one a gamble. I purchased similar power supplies, and they will only burn out your NAS board. However, you can rewire them and use on your DNS-323 without any issues as long as they provide 3 Amps on both rails; I am telling you that because I've successfully rewired a T-Power power supply. Good luck.
