I purchased a 323 at Christmas in 2008 along with a pair of WD 1 TB drives. I don't babysit it much - if I need it, I turn it on and it may run for a few months before I turn it off. And then it might remain off for a couple of months. I use it for manually backing up photos, etc.
I went to turn it on yesterday and it won't power on at all. When I press the button the disk LEDs will blink blue for a small fraction of a second and then go out. If I press and hold the button, then the disk LEDs will blink blue for a small fraction of a second about once every second. The light around the square button never lights up. The power adapter has a green light lit on it.
If it's helpful, the last time I know it was working was about 2 weeks ago. I added a light fixture to the room where this unit is. I remembered to power down the PC, but not the other items sharing the power strip. Power was killed and restored to the room a few times before I remembered to disconnect the power strip.
I'm looking for advice...
1. Is it obvious enough what failed in the unit where I could attempt to get a spare part and replace it?
2. If no, I have to put together a data migration plan that doesn't assume a working 323. Since I had it configured in RAID1, I should be able to pull drive one or two out and connect it to a PC running an OS that can read the FS, right? Any gotchas here to be aware of?
Thanks for your help.

Can you check the power adapter to make sure it's out putting correct voltages? Look at the sticker on the power block then measure whats coming out of the plug. If nothing at the plug, could be bad power adapter.
-
Thanks for the fast response.
Sticker has 4 pins (+12V, +5V, and two returns). 12 pin putting out 12. 5 pin putting out 5. So the adapter checks out...
-
Then the DNS itself is the problem. You may want to get a hold of Ivan here in the forums an see if there is any help he can provide. If you done the basics, then the unit maybe bad. :-\

D-Link direct does not sell replacement parts for these units. Assuming you can identify the bad component, your best bet is finding a third party resource, possibly even another dead DNS-323 from which to salvage parts.
-
Thanks for the help. I'll explore both of those options a little more before moving on...
Assuming for a moment, though, that it truly is dead and I can't do anything to fix it, was I correct that I should be able to pull either drive and connect it to a PC (running an OS that can read the FS) and pull the data?

Perfect. Thanks for all your help.

Glad to help. Post back and let us know how everything turns out.
BTW -- Is it possible the power brick is bad? That's probably the easiest part to replace if you can find a replacement with comparable specifications.

The fact it has correct voltages measured without load is meaningless, it is the voltage measured when the load is applied that matters. The description of the problem is typical of a power supply that has components that are only just working - usually the driver transistor - and supply enough power to charge the output capacitors to the control voltage but can not sustain that voltage under load - the indicator LEDs light but then go out.
In this case the first thing to do is to find, borrow, another power supply and try that - it is possible to use a dual variable voltage lab power supply but this requires opening the unit to get at the main board and the power connectors.
-
Got the same problem myself. I took the power supply to work to get it tested.
We discovered that, as Ivan stated, there is enough initial charge but as soon as any load is applied to the power supply the voltage drops to 0V.
We decided it was easy to source a new power supply than repair it.

Edit
Update
I sourced a new power supply from aliexpress and the DNS-323 is up and running again. I made sure the output was 5V/3A, 12V/3A

I'm glad everything worked out. Do you have a link to the exact product you purchased for other users who may be facing a similar situation?

Hello,
I know this is an older thread but I am having the same issues with my unit. LEDs glow dimly but go out, unit will not power up, tried a new power supply and same issue. Looked on the main board but I see nothing out of the ordinary, nothing bulging or leaking, no shorts. Does anyone have any idea what may be the issue? TIA
-
When you say you tried a new power unit was it rated at 12v@3A and 5v@3A?
If the new power supply fits the specifications the next thing to do is to mark each drive with the slot it is in (L / R) and then remove the disks (the marking is to ensure they go back in the slot they were removed from).
With the disks removed power up the unit. What is the state of the power LED and the network LEDs? Is the fan running?
We have seen one instance of a fan failing with a short circuit that caused the 5v rail to power down which made the unit not work. I am not saying it the cause of your problem but the LEDs get their power from the 5v rail as does most of the electronics (main board and drives, the 12v is mainly for the drives).
-
Hello, thanks for replying.
It is a new power supply by the same manufacturer with same specs, exactly the same.
Disks removed same issue occur exactly the same.
Fan does not power up but it is a replacement fan that was installed a year ago.
Drives never power up at all.

OK, now comes the hard part you are going to have to take it apart and get the volt meter out and do some measuring. The problem with that is I can't tell you where to measure voltages until I get into the office on Monday - I just don't keep that information in my head.
There is another thing you should look for when you get the unit apart and that is dry solder joints. Using a good magnifying glass look at the solder of the joints on things like the power socket, the sockets for the disk mounting daughter boards and the disk sockets on those boards themselves.
Also check that the ICs and processor are not getting too hot (a finger is a wonderful temperature probe). Check that fan as well just in case.
-
Will do, no rush either and you are a giant fountain of great information, been reading through some of the other threads and you are a great help to the community!

Just a quick update while I wait for a disk re-imaging to complete - the borg struck one of our clients over the weekend.
I have not be into the office yet but I would ask you to check the voltage at the socket when you get the unit apart and then check the voltage at the LEDs. This should give some indication of possible main board problems.
