...due to a power failure.
Unfortunately the normal state after a power failure is OFF. I would like the DNS 323 to come up automatically - if I am abroad and power fails there is no way for me to push the power button obviously. I find it absurd and totally contradicting the functionality of a NAS if the DNS 323 does not power on again after a power failure.
Can I just short cut the power button to make it work?

there was a post here a few weeks ago with a solution (with a web page and photos) for this - search the forum for it.

I think you mean this: http://dns323.kood.org/forum/t963-Autom … lied.html.
Unfortunately it doesn't solve the problem :-(

Keep searching - there are at least two threads with "add-on" circuitry that will do exactly what you want.
However - please be aware that auto turn on is only half the solution - if you don't have a UPS and you are writing to the unit at the time of the power failure you can end up with a corrupt file system, so you need UPS monitoring (which has just been added in fw 1.06) along with a UPS that will come back on line when the power is restored and some way of notifying you (at the remote location) that there has been a power failure so you can stop using the DNS-323 before it shuts down.
Just so that you're aware of it - the UPS monitoring is not configurable and allows the UPS to run to full battery depletion - if you get a second outage directly after power is restored from the first outage and before the UPS recharges it's battery ....

no, it wasn't that thread. I will have a look later on and see if I can find it.

Thanx!
I have searched and did not find anything usable.
By the way: actually I want to be able to switch all three DNS-323 on using a radio controlled RF powerstrip. Powering off can be done by by WebIF...

Powering off can be done by WebIF
Only if you happen to be online and connected when there is a power outage - and then only if you're aware of the outage.
Here's the thread with the other circuit - it points to this page
It sounds like you're now moving towards powering it on remotely and then powering it off when you're finished using it - that doesn't, at least to my mind, change anything I posted earlier about needing a UPS, etc. to avoid file system corruption - you'd need to know how often you experience an outage, which I would assume is not an infrequent occurence, since that was the reason you opened the thread.

Hi Fordem!
Thanks for the link!
I just used the power outage as an example.
In fact it is all about remote powering on and off! Powering off can be done by the WebIF ... I do this very often (I have a small low power XP server that i RDP into to mange my devices at home).
My problem is powering on. I'll check your link and give you some feedback!

Sounds like you have it all worked out - I've never gotten around to building and testing that circuit or a simpler one of my own design - maybe some time this year.
Offline
Yeah ... got it all worked out in THEORY. But now I'm going soldering. That will be big fun - NOT :-)

Come on - that's a simple circuit - it's low frequency, low voltage, a square inch or two of perf board, a single IC a couple of caps and diodes - nothing to it.

We had a similar need for automatic power on after a failure. I've posted a simple circuit that uses a 556 timer chip, with assembly instructions, to the DNS-323 wiki that does the job well. It waits for at least 10 seconds of clean power, then turns on the DNS-323.
So that it is easily accessible to all, you can find the circuit on the DNS-323 wiki at hardware:autopoweron.

Great idea but it does not work on old hardware revisions of DNS-323, where the switch is connected to +12V over a resistor and when depressed it actually raises the voltage on the other pin to 11.5 Volts. I have built your circuit but it needs to be modified for the old revisions (perhaps a PNP transistor connected with E to the +12V pin (your ground), C to the other pin and driven by the auto power on circuit over a resistor to B?)

Verified working with the older hardware revisions after adding one PNP transistor driven from NE556 pin#9 over 47 kOhm resistor to its base. Emitter is connected to the part of the switch marked with the grounding symbol, collector to the other end with yellow wire on the picture.
Any signal PNP will do, I am using BC560.

Thanks skydreamer! I modified the wiki page to include a schematic for older hardware revisions now too. You might want to check the text there to:
1. Clarify what the top and bottom sides of the switch look like. I don't have an older version so I'm not sure. We just want readers to be sure that they connect the emitter to the top (more positive) side of the switch and the collector to the bottom side.
2. I know that hardware version B1 (which I am using) has the switch to ground. Do you know which are the version numbers that have the pull-up switch instead?
Thanks for your addition to the wiki page!

Hi MosaicPaul,
The bottom side of the switch looks as shown on the first photograph in the wiki. Emitter is soldered to the top (next to the blue wire), collector to the bottom switch contact (instead of yellow wire). I am not sure how to tell the hardware revision? Is there a sticker or some sort of id?
I used a universal PCB, two columns of three hole contact pads in 8 rows, wired up the connections under the IC using the inside holes, soldered the IC to the middle holes and used the outer holes for those few components. The last row below pin 7 is for one of the 10uF caps, which connects between pins 7-8. It is a very compact layout and looks pretty professional. Finally I insulated the entire circuit using heat shrink sleeving on the PCB and the transistor soldered to the power-on switch. It is quite neat but takes over 2 hours to finish.
Cheers!
