M1000E Power question

Question

I am following this guideline:https://i.dell.com/sites/csdocuments/Business_smb_merchandizing_Documents/pt/br/pe_m1000e_selection_whitepaper.pdfOn page 23-24,  under 'Special Case – Power Supply Redundancy for two Chassis using two 24 Amp Single-PhasePDUs':Figure A5 shows two PDUs on seperate 30a breakers connected to eight PSUs to provide redundancy  between two chassis.Can I use a third PDU on a third 30a breaker/circuit to power the remaining four PSUs in the same fashion?Thanks.

Hello, it is not about how many PDUs, it is about how many independent power sources

I'm wondering if you are trying to tell us if you have 3 independent power sourced in your DC?

For more info about supported PSU combos he can refer here

@DELL-Young E​  Yes, three independent power sources.  I am wondering if PSU5 and PSU6 on both chassis can be powered the same way on a third 30a source. From what I understand, the other two 30a sources are good enough for a moderate load, but not a full load?

Logixworx,   I am not seeing anything that is to the contrary for you to be able to do it, but I am also not seeing anything that confirms you can. In my opinion I believe you should be able to.
