dc input voltage requirement for Proliant XL series server boards

Hello,

I am a research assistant at a university, I am trying to build a server rack for a power delivery research project.

I am going to build my own power supply and ups combination for the server board (preferably one of the Proliant XL series, half size boards.) I tried to find out the DC input voltage requirement for the boards but I couldn't. Is such an information available?

I specifically want to know the allowed voltage range of the onboard voltage regulators. Can I swing the server board voltage 10.5V-13.5V?

I will basically connect 12V ups at its input and demonstrate a power loss scenario, I want to make sure the board can operate.

Thanks in advance.
