Configuring the number of redundant power supplies

Redundant power supplies are reserved for power supply backup and power supply threshold alarming. With multiple redundant power supplies configured in the system, if a power supply fails or the system power supply is overloaded, the system automatically enables a redundant power supply. As a result, the number of redundant power supplies decreases by one.

If power supply management is disabled, the system does not reserve any redundant power supply. In this case, you can also use the power-supply policy redundant command to configure the number of redundant power supplies, and this configuration will take effect after power supply management is enabled.

To configure the number of redundant power supplies:

Step	Command	Remarks
1. Enter system view.	system-view	N/A
2. Enable power supply management.	In standalone mode:power-supply policy enable In IRF mode:power-supply policy enable chassis chassis-number	By default, power supply management is enabled.
3. Configure the number of redundant power supplies.	In standalone mode:power-supply policy redundant module-count In IRF mode:power-supply policy chassis chassis-number redundant module-count	By default, the number of redundant power supplies depends on the reserved power, which you can display with the display power-supply command.
