DC power supply configuration guidelines
Determine the number of DC power supplies based on the system power consumption and the DC
power supply configuration based on the power input mode.
•
As a best practice, configure N+M (M
≥ 1) DC power supply redundancy. Make sure N+M is not
larger than the total number of power supply slots.
N is the number of DC 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 or fuse for power input of each DC power supply. Make sure each input
line has a current carrying capacity not less than 100 A.
Installing a DC power supply
1. Thread a flat-blade screwdriver through the hole in the handle of the filler panel and pull the filler
panel out.
