scope:
The present document is applicable to the case of multiple power feeding configurations at the input of ICT equipment in ICT system.
The present document describes the combination of three power interfaces as A1 (AC), A (-48 VDC), P or A3 (up to 400 VDC) that could potentially be used single or in combination for each input.
The present document also provides details of the power structure within the ICT equipment, between the ICT equipment interfaces and ICT equipment system loads that is inclusive of system power converters.
The input power configurations are categorized to allow for better understanding and identification of each new multiple power feeding interface, providing details of the impacts and benefits of adopting them. Information is also provided on the impact on battery test function when used with the different dual power inputs combinations.
Lastly requirements are given for avoiding the potential risk of voltage back feeding from one input to the other and for general isolation requirements in all multiple power feeding configurations.
