dell server power supply

Hi,

I have a Dell 2650 PowerEdge server power supply that I would like to use out of the server. Does anyone know how I can do this? This is a little trickier than with an ATX power supply as 1) the connector is 6x4 pins, 2) I cannot identify PSON, which I have read maybe pin 11 or 16 3)Grounding 11 or 16 does not work anyway.

In reply to: tried 13 to 14?

Thanks for the suggestion.

I'm not really sure where pins 13 & 14 are, but I've tried the combinations that I could guess, and the supply did not power up.

My pins are arranged in four rows of six pins:

. . . . . .
. . . . . .
. . . . . .
. . . . . .


When looking at the connector the voltages are:

5.14 5.14 5.14 0.00 0.00 0.00
4.04 4.04 0.01 0.01 5.27 0.00
4.62 4.53 0.00 2.19 4.76 0.01
0.00 0.50 0.00 0.00 0.40 0.00

Hope this helps. Which is pin 1 & which is pin 24?

Can you help me a bit more James?

I have listed above the voltages that I have on the connector. I also have access to a 2650 server. I'm still not sure of the pin numbering. Any help would be appreciated.

Thanks

Why are you doing this?

In reply to: more info

And why aren't you using the hotswap sled or tray that works with it?

If you are getting power output readings from the power supply, then is it not on already? I read too quick before and gave you a wrong answer off the top of my head about PSON for ATX, it's actually jumpered between 14 and 15. http://www.duxcw.com/faq/ps/ps4.htm

Here's an info page for the server referenced, there's a cabling pdf file available there.

For anyone reading this thread, here's the power systems he's dealing with. Clk on one and can get larger picture of the 4x6 pin out.

Dell 2650 power supply

Please ignore the above post, it's a duplicate.


OK, Why am I doing this? well I need a couple of bench power supplies and I have these already so I thought I would use them if I could. They are quite powerfull and robust.

When the mains lead is plugged into the power supply there is power on the 24 pin connector (as detailed above), however, I'm assuming that this is low amperage and just for the power supply to communicate with the server (fault lights, fan speed etc..). The LED on the back of the power supply indicates that it is in Standby Mode. The power connector is not the same as an ATX power supply (or a Dell PC). The power supply has two large power connectors (pins) at either end, and 24 pins in the middle (4 rows of six pins). The pins are small, like jumper pins.

The cables in the links in the above posts will not connect to this power supply.

I'm assuming that, like normal ATX PC power supplies, I need to connect PSON to something (VFP, VDC) to get the supply to turn on.

I have read all the documentation on the Dell site that I can find, but nothing so far describes how to get the power supply working outside the chassis. I did find a schematic which shows a 6100 where PSON, VFP, VDC go to the On/OFF button (http://support.dell.com/support/edocs/docs/53861.pdf),on the front of the server. But this is still not enough information for me to get the supplies to power up.

I feel like it should be so easy, just jumper two pins or something, but it's beat me!

Isn't that it on page 60?

aka 4-12
You've reversed this action done for removal?

Turn the locking switch on the power supply from the locked position
(1) to the standby power position (partial circle with a line through the top).


Did you try it with that locking switch turned back to the locked position?

Found It.

Your Right

In reply to: Found It.

I don't like it. In fact I don't completely understand it. So looks like I'll have to buy a couple of ATX power supplies instead!!

Solved!!!

In reply to: dell server power supply

So, I was looking to use a 9650 as a 12V Power Supply. In order to power the device on short the following pins, assuming a 4 row x 6 column set of pins:

row 2, column 5
row 3, column 4
row 4, column 4

By connecting these three pins together (bend and then use a touch of solder) the power supply will turn on supplying 12V to both rails (right side positive, left pair neg) when the AC source is plugged in. Hope this helps - it took me a while!

Yes!! But now another problem :)

In reply to: Solved!!!

Hi all. I have also managed to get it started. Have to check the pins when i get home if they are the same. Atleast here is a picture on mine with two jumpers shorting 2 pairs of pins:

http://www.bunkerjavel.se/bygge2k7/IMG_1529-edit.jpg

Now I'm facing another problem with this power supply. I'm using it to power a 12V car amplifier. When the AC source is plugged in and I turn my 3-way switch (on-off-on) on, the power supply dies. It lights the red alarm lamp and i can hear the fan slow down and stop. What I can do though, is to have my switch turned to on. Then afterwards put the AC source online, have the power supply to start up and then use my switch to turn my car amplifier off, then on as many times I want to. Anyone having similar issues? What makes the supply to die if it's running and then adding some load by turning a switch on?
