USA | So what, it's a paper weight now? (Yes, it's not strictly on topic as it's regarding something for my personal rack at home, but it is dealing with 'enterprise' hardware and such)
Seriously? This can't be typical...
Recently got a D-Link DSG-3100 true managed switch (not the 'I-play-one-on-TV' smart switches), and the power supply decided to give out.
(Considering the amount of dust that was in the thing, I'm surprised to didn't choke sooner, but that's another subject...)
I email support, and they tell me that D-Link does "sell internal power supplies for the switch;we can only offer replacement if the switch was still under warranty."
Wait, what? It's not in warranty, I already specified that. Another email exchange, and support tells me that I should call customer service.
The CS rep (very nice woman, no complaints against her) tells me that according to the warehouse, they don't offer the internal PSU as an part that can be ordered.
I've emailed support again asking for further help as they said it can be done, but CS is saying no. I'm not holding my breath on that going very far, but who knows...
So those of you who have dealt with other companies, is this 'normal' for non-EOL'ed but out of warranty kit? Do other companies expect us to just buy a new one and toss the old when an easy to replace part is all that is needed to put it back into a serviceable state?
Unfortunately, work is Cisco/Dell, so I can't use any contacts I have from that route.

Since it’s a paper weight at the moment, open it and have a good look at the PSU, often it’s not built on the main switch circuit board but rather has a completely separate one.
If it has marks you may be able to find out who actually made it, find a used replacement, or possibly figure out what sort of specs it had (i.e. voltage outputs, max current, etc.). Frameless/open PSU are out there via various electronic supply houses, provided you can find one which fits into the space, and meets the requirements at a reasonable cost it might be worth while.
I have a PoE midspan that uses three separate internal power supplies, one of them crapped out and took out half the ports. The company wasn't interesting in offering support but instead had the sales drone call - hmmm no thanks! I did what I just described above and fixed it. Its unlikely to find a open PSU that has the same footprint (i.e. same screw hole positions) so be prepared for a bit of fiddling and modding to safely mount it.
RANT - I am convinced it was built to self-destruct, they used only the cheapest fans on the chassis, greatly undervolted them so they operated dangerously close to stall speed, and after finding the specs for the original PSU, these fans didn't come close to providing the necessary air flow to cool the PSUs even if they had been operating at full power. Built to break!  /RANT | |

Frameless/open PSU are out there via various electronic supply houses, provided you can find one which fits into the space, and meets the requirements at a reasonable cost it might be worth while. I've already opened it up (the amount of dust inside it was bad enough that having it sit on a flat surface and tapping the case would show dust falling out of the fans on the side) and I know the manufacture of the supply board (Tiger Power, I don't have the model handy), however, the company that made it doesn't appear to have any specs available on their web site, and they have a big notice on their contact us form that they do not offer any support to end users.
Of course, D-Link doesn't provide the power information either, so at this point, I think my only real choice is to try to figure out which part popped (unfortunately, there isn't anything obvious that points to where the magic smoke escaped), take it somewhere to see if they can figure it out (general electronic repair shop perhaps), or suck it up and never again buy anything with the D-Link logo for myself or any clients, friends, work, etc.
Too bad really, the switch appeared to be decent.

I'm regretting it now.

Thanks for looking, I do appreciate the suggestion. However, that's for the external DC unit, which costs as much if not more than I paid for the switch itself, and is designed to fit in one of their redundant power chassis. I could set it on a shelf, but it kind of defeats the purpose of the rack. 
If I could find a pin-out for that DC plug on the switch or the DC supply, I might be able to rig something up to run it that way at least, assuming that the 48 port model doesn't use a different plug from the 24 port.
Amusingly (kind of), D-Link's email support group pointed out to me that D-Link "provides ample warranty and even lifetime warranty to our products". I guess they forgot that said warranty only applies to the original buyer, which I am not.

| According to the link: »ftp://ftp10.dlink.com/pdfs/products/DP···s_ca.pdf
Output Voltage +5, +12 V
Power Capacity 140 Watt
So if you have an old ATX (or even a most ancient AT) computer power supply laying about you could at least test to see if the switch will power up. You would still have to sort out where to make the connections on the switch. If you look in the manuals for the switch and external D-link power module they may have a pinout or description.
Not sure about the accuracy of this but it might help:

Yes, I found that site and saw that pin out. Seeing the question mark on the comment for pin 5 makes me a bit hesitant to try it, but it's the best I've found so far.
Unfortunately, I don't have any of my AT power supplies around any more (heh), but I do still have some old scary looking ATX (you know, the ones that weigh less than a box of cracker jacks) laying around, and I thought about that last night as well.
OTOH, I pulled one of the MOSFET's out and if I did the testing right with my DMM, I may have got lucky and found the blown part (infinite on both sides, even after doing the charge up the other side bit). Won't know until I can pickup a replacement and solder it back in.
Thanks for doing the googling, I do appreciate it!
