Power supply requirements
The minimum number of power supplies needed in your system for operation and
to achieve redundancy depends on the blade and port configuration and the AC
input voltage level. N is minimum number of power supplies to operate
configuration, N+N doubles power supplies for full AC input and DC output
redundancy, and N+1 adds additional power supply for DC output redundancy in
case of single power supply failure. Although examples for different port and
blade configurations are provided, for more information and help with
determining the actual number of power supplies for your deployment, contact
your local representative.
