Power supply configuration
You can determine the number of power supplies to be configured for the system
according to the actual power consumption and power supply conditions.
• In an environment with two mains power inputs, you can configure N+N redundant
mode.
• In an environment with only one mains power input, you can configure N+1 or N+N
redundant mode.
• For easy usage and maintenance, be sure to configure a proper circuit breaker for
each power input. The rated current of the circuit breaker must be more than 20 A.
NOTE:
In the term
N+1 and N+N , the value of N depends on the number of power supply
slots in the device. N+1 or N+N must not be more than the total number of power
supply slots.
