DSM-G600, DNS-3xx and NSA-220 Hack Forum

Thank you!  Well, the cooling choice D-link implemented:

40mm fan is an ADDA AD0405HB-G73 - 10mm thick, 5 Volts, 0.25 Amperes.
Power = Current x Volts, so That's .25 Amperes x 5 Volts  ==  1.25 Watts for the fan if at full power.

It's a DC Brushless, High speed, Ball Bearing, 7blades, Motor protective circuit & third lead wire by integrated circuit with speed sensor (FG) according to the manual at the Adda website.

Though it's missing from the chart on their website here: http://www.addausa.com/specifications/up-40.pdf
It looks like it would probably be a 6000 rpm fan, with an airflow of 6.7 or 6.8 CFM, 0.100 (inches) pressure, sound of 25dB/A, and it weighs 24 grams. : ).

I read somewhere in the d-link marketing literature that they might temperature-control the fan speed, too, though I don't have details.

The fan speed is indeed temperature controlled, which to me feels like a luxury in this price class . However, I can not yet tell if it's controllable by software, or fully independent...

By the way - you see the shape of the plastic back-cover protecting the fan? A funny detail is that its cut-outs seem to be the main source of the "taxing jet plane" kind of ambient noise which is the only sound the unit emits after the disks have spun down.

It's not at all much of a noise really, but it's the knowledge that it might be increased by such a simple design flaw that bothers me. I'll probably cut out the piece covering the fan outlet some day just to see if I'm correct...

That sounds interesting cbrunnkvist!

One way of telling what is CON5 for would be to trace the track back to the CPU and then using the PIN layout to make a qualified guess.

Perhaps it is another USB connector?

CON4 and the magic number is definitively a good progress, now I need to make a PCB for MAX232 to start some serious hacking....

i can set up a wiki on dns323.info when i got my new server up running my server lost all inbount connections on port 1-1023 after i moved to a new isp.(stupid swedish isp)

That would be awesome! Btw I got the impression that dns323.info was owned by a danish guy, don't know why...

Let me know if you can't get your ports and stuff working, and we'll come up with some other hosting option

I can setup a wiki in my server with no problems
For example, if you like, you can point dns323.kood.org (or any other domain name for dns323 wiki) to
p1.xservu.com
dns2.xservu.com

It looks like there is a software tool for this!  see:

If you do it, I'm really interested in if it would help!  Don't let me peer pressure you into screwing up your box, though, man : ). best! -sg

Good evening fellow hackers! Following a request in #nslu2-linux on Freenode, I took the time to open up my new DNS-323 and shoot a bunch of photos of the main board and its components.

URL: http://duplo.org/~conny/dns-323/

Hopefully this will help us straighen out anyones questions about what hardware (version A1) that's actually in there.

Hi, the link is dead.  Any chance you still have the pix somewhere?

Thanks,
Bob

Yes.  I did see that one.  I have a 343, don't know if that makes a difference. 

I am having a problem getting the rear cover off to replace the circuit board and am looking for the "secret" so I don't break something. The 323 photos weren't too helpful.

Thanks,
Bob
