to the default setting, use the default form of this command.

Command Modes Global configuration mode
Command History
Usage Guidelines The two power supplies must be the same type and wattage.
Caution If you have power supplies with different types or wattages installed in your switch, the switch will not
recognize one of the power supplies. A switch set to redundant mode will not have power redundancy.
A switch set to combined mode will use only one power supply.
In redundant mode, the power from a single power supply must provide enough power to support the
switch configuration.
Table 2-12 lists the maximum available power for chassis and Power over Ethernet for each power
supply.
redundant Configures the switch to redundant power management mode.
combined Configures the switch to combined power management mode.
Release Modification
