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 on the AC or DC input voltage level. N is the minimum number of power supplies to
operate the configuration; N+N doubles the number of power supplies for full AC or DC input and DC output redundancy;
and N+1 adds an additional power supply for DC output redundancy in the case of a 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 Brocade representative.
NOTE
In the following table, HVAC and HVDC indicate voltages from the high-voltage AC and high-voltage DC power
supply.
