Power Vault MD3460 Power Voltage

Greetings,

Does the PV MD3460 work on both 110v and 220v power sources? or only 220v? the specifications state it has an auto ranging PS 220v and we are getting mixed answers from Dell base on who is answering

One would say it is auto ranging from 110v to 220v and would work on wither power feeds - and one would say it is strictly 220v.

Appreciate the help.

Thanks
