Performing power supply management

Enabling power supply management

Some power supplies have self protection mechanisms. When such a power supply encounters an
overloading, over current, over voltage, over temperature, or short circuit problem, it implements a
hardware protection measure to protect the whole device from being damaged, for example, powering
off the device. Powering off the device helps protect the device, but doing so also interrupts the services.
The power supply management function can minimize service interruption while protecting the device.
The power supply management function constantly monitors the available power and the system loads
and takes protective measures in response to a potential power supply problem immediately so the
power supplies do not need to perform hardware protection. Examples of protective measures 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, so the device can automatically start the redundant power supply and
send trap information for alerts when a power supply in use fails or is removed, or when power
consumption increases. You can view the power supply information of the device 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
