Configuring The Number Of Redundant Power Supplies; Manually Starting Or Stopping Power Supply To A Card - H3C S12500 Installation Manual

To do...
Enable power supply management
on a specified member switch (IRF
mode)

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.
Follow these steps to configure the number of redundant power supplies:
To do...
Enter system view
Enable power supply management
(standalone mode)
Enable power supply management
on a specified member switch (IRF
mode)
Configure the number of
redundant power supplies
(standalone mode)
Configure the number of
redundant power supplies on a
specified member switch (IRF
mode)
NOTE:
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.

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.
