The available power equals the combined output of all installed power supplies. There is no reserve
power. You activate this mode by using the power redundancy-mode combined command.
The following table shows the results for each scenario.
The power supply that outputs the most power provides the reserve power so that it can take over for
any other power supply that fails, and all of the other installed power supplies provide the available
power. You activate this power mode by using the power redundancy-mode ps-redundant command.
The following table shows the results for each scenario.
The available power is provided by one power source and the reserve power is provided by the other
power source. If the power source providing the available power fails, the switch uses the reserve power
source to provide its required power. You activate this power mode by using the power
redundancy-mode insrc_redundant command.
The following table shows the results for each scenario.
Full redundancy provides both power-supply redundancy and input-source redundancy. For power-supply
redundancy, the power supply with the most output provides reserve power and the other power supplies
provide the available power. For input-source redundancy, the available power is provided by one
power source and the reserve power is provided by another power source, with You activate this power
mode by using the power redundancy-mode redundant command.
The following table shows the results for each scenario.
