Power supply configuration guidelines
Determine the number of power supplies based on the system power
consumption and the power supply configuration based on the power
input mode.
•
In an environment with two mains power inputs, configure N+N
power supply redundancy.
•
In an environment with only one mains power input, configure
N+1 or N+N power supply redundancy.
•
Provide a circuit breaker for power input of each power supply.
Make sure each circuit breaker has a current rating not less than
20 A.
NOTE:
The value of N depends on the number of power supply slots in
the device. N+1 or N+N must not be greater than the total number
of power supply slots.
