Manually starting or stopping power supply to a card
When the switch is operating, you can start or stop power supply to a card to adjust the system available
power as needed.
Configuration guidelines
Before starting power supply to a card, confirm whether the power supply is overloaded after supplying
power to the new card. If the maximum power consumption of the system is greater than the available
power after supplying power to the new card, the system performs one of the following options:
• With power supply management enabled, the system does not supply power to this card because
of the self protection mechanism.
• With power supply management disabled, the system becomes unstable or the switch reboots
because of power supply overload.
For more information about power supply management, see "Enabling power supply management."
