Power module configuration

You can determine the number of power modules 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 module

slots in the device. N+1 or N+N must not be more than the total number of power
module slots.
