Power for a Dell Poweredge 6850: 240v with 120v

March 24, 2013 at 20:26:40
Specs: None, 4 x XEON 3.0 Ghz / 32 Gb Ram
Hello world,

I recently acquired four Dell Poweredge 6850 servers. Individually, their specs are
CPU: 4 x XEON 3.0 Ghz processors
RAM: 32 GB
No HDs
Power rqmt: 200-240v

I got these to experiment and to learn, but I'm having problems powering them up. Since they're powered using 240v outlets, which generally power stoves or dryers, I'm very limited on how to keep them up and running consistently. What are my options? Can I use a step-up converter to power all four? Just one? Do I need to get an electrician to install a 240v outlet? How much would that cost?

Any information you can provide will be greatly appreciated.

I'm not an electrician so perhaps you should consult one about either a step-up converter or rewiring.

It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.

I looked and Dell only offered a 220v power supply for that server, so you will have to rewire your place or get a big step up transformer. It looks like the max amperage draw of each power supply is 8.21a @ 208v = aprox 1700w so you will have to get a transformer that can handle at least that. Keep in mind that this is the max draw, normal usage is most likely 3/4 of that @ aprox 1275w. Also remember that if the max draw of the system is 8.21a at 208v then the amprage will be double that at the socket that has 110v so your max draw will be around 16a at 110v so you will mostlikely pop a 20a breaker if you plugged two of these in.


If you do plan on using these servers, I would recommend that you will have to have an electrician come in and wire you up. Or you could sell those servers and buy some that suits your environment.
