AC power supply configuration guidelines
Determine the number of AC power supplies based on the system power consumption and the AC
power supply configuration based on the power input mode.
•
As a best practice, configure N+N (dual power sources) AC power supply redundancy. Make
sure N+N is not larger than the total number of power supply slots.
N is the number of AC power supplies.
•
Make sure the total output power of the power supplies is greater than the system power
consumption (with a 20% power surplus as a best practice).
•
Provide a circuit breaker for power input of each AC power supply. Make sure each circuit
breaker has a current rating not less than 20 A.
Installing an AC power supply
1.
Thread a flat-blade screwdriver through the hole in the handle of the filler panel and pull the filler
panel out.
