Power Supply Configuration Modes
You can configure one of the following power modes to either use the combined power provided by the
installed power supply units or to provide power redundan cy w he n th er e i s a po wer lo ss:
• Combined mode—Provides the maximum amount of available power by utilizing the combined
power output from all installed power supply units for device operations. This mode does not
provide redundancy.
• Power-supply redundancy mode—Allows you to replace a power supp ly during device operations.
All power supplies are active. The available power is calculated as the least amount of power
available from all but one of the power supply units (N+1). The reserve power is the amo unt of
power output by the power supply unit that can output the most power. For example, if three power
supply units output 3 kW, 6 kW, and 6 kW, the available power is 9 kW (3 kW + 6 kW) and the
reserve power is 6 kW.
• Input source redundancy mode—Takes power from two electrical grids so that if one grid goes
down, the other grid can provide the power needed b y th e devi ce. E ach grid po w ers ha lf of eac h
