PDU specs for xe 9860
Looking for a PDU specification for the xe 9860. The 9860 has 5+1 redundant 2800 watt power supplies, with c21 connectors. Trying to determine what is the actual current draw for these power supplies? Any recommendations for a PDU configuration to plug these power supplies into?
Thanks!

Hi, in some cases, Dell has a tool(Enterprise Infrastructure Planning Tool) that you can use and which I believe can be useful. I think this might help. https://dell.to/3XXHlrc Other than that I can't find specific information about PDU configuration.

Thank you, Erman. I had found that tool previously, and it is helpful but yields different results than what is referenced in the technical docs and what Dell Sales has communicated. The docs imply each power supply draws ~15a, so 6X15a would equal ~90a. That seems to be a "rated" number, as each c19/c21 would we de-rated to around that 15a value. The Enterprise Infra planning tool indicates a draw of just under 40a. So the question is, does the xe 9860 require a 60a pdu (de-rated to 48) or a 100a pdu. This is a significant gap between those 2 choices.
