UCS Question

[J D]

We have a UCS5108AC chassis with 2 2104XP I/O modules and 1 B200 M1 Server.  We recently purchased 2 UCSB-PSU-2500ACDV power supplies.  We are wanting to use the 110v capability off of the new power supplies.  My question is will this work.  The only documentation I can find is support for the 6324 FEX using 110v.  I don't see anything else stating if the 2104XP's need 220v to operate and the same thing for the B200 M1 Servers.

clearly says

Table 9 AC-input Dual Voltage Platinum Power Supply (UCSB-PSU-2500ACDV) Specifications

Description	Specification
AC-input voltage	200 to 240 VAC nominal (Range: 180 to 264 VAC) 100 to 120 VAC nominal (Range: 90 to 127 VAC) supported only with the UCS 6324 Fabric Interconnect

Walter,

So there is no way of testing to see if this would work.  I am trying to find documentation on where cisco did the test I was requesting to see the results.  I have run into the information you provided but that is it and nothing more. 

It would be nice to see the voltage requirements for the I/O modules, Servers, etc.. in the UCS5108.

My question still remains, what will happen if I use this power supply on the equipment?  Will the unit not power on, will it short out the equipment, will I burn the data center down, etc..
