Dlink DNS-321 NAS - No power
Hey everyone, I picked up a older D-Link DNS-321 NAS unit without a power adapter last winter and I finally ordered a replacement Jentec JTA0512 power adapter.
The adapter just arrived recently so in some form of excitement I plugged it in and to my dissapointment, the DNS-321 unit doesn't power on.
I brought the adapter and NAS box to work for my 12 hour shift and started to strip it down and try to observe what could be wrong.
After doing a successful capacitor replacement on an iMac using this great forum, I feel that I can identify a blown/faulty capacitor.
To start off, the power adapter has a 4-pin DIN connector. Two pins don't read anything with the multi-meter (grounds?) but the other two read 5v and 12v.
Other then that, I am unsure what to look for or check. The main board doesn't show any signs of any chips being burnt. All solder points look fine from the eye but I haven't used a magnifying glass to inspect them.
When the power is attached to the NAS unit here is what I've observed:
I know this box isn't worth much at all but for education purposes, I'd love to try to figure out why it's not working and attempt to fix it. This is a Linux based device and it would be neat to fire it up and play with it slightly.
Here are a slew of pictures I took of the board:
If anybody has a suggestion on what I can look at next, it would be greatly appreciated :-)

- Power button/reset button don't do anything
- No diodes light up at the front
- The fan doesn't spin up
- I've tried to do a hard reset on the box, nothing changed.
