Configure the number of
redundant power
supplies.
•
In standalone mode:
power-supply policy redundant
module-count
•
In IRF mode:
power-supply policy chassis
chassis-number redundant module-count
By default, the number of
redundant power supplies
depends on the reserved
power, which you can
display with the display
power-supply command.
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

Allocating IDs for AC power supplies
IMPORTANT:
Each AC power supply can be allocated with only one ID, and multiple AC power supplies cannot have
the same ID.
This section is applicable to AC power supply system PSE9000 only. To view the model of a power
supply system, use the display power-supply command.
For PSE9000-A power supply system, the system can automatically set the power supply ID as the slot
number where the power supply is plugged, as shown in
and
After the system starts up, each AC power supply is allocated a unique local ID randomly. The randomly
allocated ID is not convenient for device management, daily maintenance, and fault location because
the randomly allocated ID is not related with the slot in which the AC power supply resides. You must
