Power module configuration
Follow these guidelines to configure power modules for the device:
•
Determine the total number of power modules based on the
actual power consumption, the power module slot number, and
power redundancy design.
•
Determine the power module redundancy design based on the
power source conditions.
{
When two mains power inputs are provided, you can
configure the power modules in N+N redundancy. N+N must
be not greater than the total number of power module slots.
{
When one mains power input is provided, you can configure
the power modules in N+1 or N+N redundancy. N+1 or N+N
must be not greater than the total number of power module
slots.
•
For easy usage and maintenance, configure a circuit breaker for
each power input. The rated current of the circuit breaker must
be a minimum of 20 A.
Power cords
The PSR3000-54AHD power module must be used in conjunction
with power cords listed in
. Determine the power cord based
on the power source conditions.
