Command History
Usage Guidelines You can use the power redundancy-mode command only in the default virtual device context (VDC).
You can configure the power supplies with the following modes:
• Combined mode—This mode does not provide power redundancy. The available power for this
mode is the total power capacity of all power supplies.
• Power supply redundancy mode—This mode provides an extra power supply in case an active power
supply goes down. With this mode, the power supply that can supply the most power operates in the
standby mode. The other one or two power supplies are active. The available power is the amount
of power provided by the active power supply units.
• Input source redundancy mode—This mode uses two electrical grids, each one powering a half
module within each power supply. If one power grid goes down, each power supply continues to
draw power through its other half module. The available power is the amount of power by the lesser
of the two grids through the power supplies.
• Full redundancy mode—This mode combines power supply redundancy and input source
redundancy, which means that the chassis has an extra power supply and each half of each power
supply is connected to one electrical grid while the other half of each power supply is connected to
the other electrical grid. The available power is the lesser of the available power for power supply
mode and input source mode.
combined Specifies the combined power supply mode.
insrc-redundant Specifies the input source redundancy mode.
ps-redundant Specifies the power support redundancy mode.
redundant Specifies the full redundancy mode.
