240V ok?

Have a computer room in a really old building were only 240V/120V (Not 208V) power is available... just like at your house.

I see that DL380 G4's have a rated range of 100-240V with an acceptable input of 90-264V. The DL360 G4's have the same rating, but no mention of the "acceptable" limit.

Is it permissible to run these servers at 240V?

This is all run from a 20KVA UPS so large amperage inputs are not a problem. I would like to use some of HP's high voltage PDU's now, as we are moving to a new building in a couple years where 208V will be in abundance and don't want to buy a whole 'nother set of stuff.

Re: 240V ok?

I believe all the HP Proliant servers starting with G2's, and maybe even some G1's, all have 110 to 240 auto sensing power supplies. I would see no problem running the 360's at 240v. Since you are on a UPS, I assume the line is conditioned and protected so you should be ok.


To get the absolute official word, I would make the call to HP.

Re: 240V ok?

Yeah after reading a bit more, I'm beginning to think the "100-240V" rating is just an inclusive list of the 100,110,120,220,208,240 standards that are out there worldwide. The real range is some standard +/- percentage at each of those points.

I'll call hp tomorrow and post the results here.

(Come to think of it, I powered a Proliant 6500 from 240V years ago with no problems! I may have answered my own question?)

Thanks...

Yup. They said it's fine!
