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.
