Power supply configuration
Determine the total number of power supplies based on the actual
power consumption.
•
In an environment with two mains power inputs, you can
configure the power supplies in N+N redundancy.
•
In an environment with only one mains power input, you can
configure the power supplies in N+1 or N+N redundancy.
•
Configure a circuit breaker for each power input. The rated
current of the circuit breaker must be greater 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.
