Power supply (n+1) redundancy mode
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.
Input-source (grid) redundancy mode
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.
Full redundancy mode
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. You activate this power mode by
using the
power redundancy-mode redundant
command.
Configuring the Power Mode
You can configure the power supply mode by using the
power redundancy-mode
command.
To display the current power supply configuration, use the
show environment power
command.
Note
Step 1
Start the configuration mode by entering the
configure terminal
command.
Example:
switch#
configure terminal
switch(config)#
Step 2
Specify one of the following power modes by entering the
power redundancy-mode mode
command:
• For combined mode, include the
combined
keyword.
• For power supply redundancy mode, include the
ps-redundant
keyword.
• For input source redundancy mode, include the
insrc_redundant
keyword.
• For full redundancy mode, include the
redundant
keyword.
Example:
switch(config)#
power redundancy-mode redundant
switch(config)#
