include sending a notification, starting redundant power supplies, and powering off certain interface
cards.
The power supply management function allows the device to have redundant power supplies for power
supply backup. For example, for a device with three power supplies, you can specify one power supply
as a redundant power supply. The device can then automatically start the redundant power supply when
a power supply in use fails or is removed, or when power consumption increases. You can view power
supply information with the display power-supply command.
The power supply management function operates in the following scenarios:
• When an interface card is inserted to the device:
{ If power supply management is disabled, the system immediately supplies power to the card. If
the power is insufficient, the system powers off the entire device.
{ If power supply management is enabled, the system compares the maximum power
consumption of the inserted interface card with the available power. If the available power is
sufficient for the card, the system supplies power to the interface card. Otherwise, the system
starts the redundant power supplies. If the total power is still insufficient, the system does not
supply power to the interface card.
• When the power is insufficient because a power supply fails or is removed:
{ If power supply management is disabled, the power supplies perform self-hardware protection.
{ If power supply management is enabled, the system starts redundant power supplies as
configured. If no redundant power supply is available, the system starts self-hardware
protection.
To enable power supply management:
Step Command Remarks

The configuration of this command takes
effect only when power supply management
is enabled.
Powering on/off a card
You can manually power on or off cards to adjust the available power. The power supply status can be
displayed with the display power-supply command.
