Enabling power supply management

If power supply management is not enabled when you add a new card by inserting it into the slot
•
or starting power supply to the card by using the power-supply command, the system directly
powers on the card, and the power supply may become unstable or the system may restart because
of overloading.
• If power supply management is enabled when you add a new card by inserting it into the slot or
starting power supply to the card by using the power-supply command, the system compares the
maximum power consumption of the card against the available power (including the redundant
power supply). If the former is not greater than the latter, the system supplies power to the card,
otherwise, the system does not supply power to the card.
To enable power supply management:
Step
1. Enter system view.
2. Enable power supply
management.
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.
