Technical Product Specification
Power Subsystem
The A and B connections provide redundant input power to both power trays. The A connections
provides power to PS2, PS4, PS5 and PS7PS1, PS3, PS5 and PS7. The B connection provides
power to PS1, PS3, PS6, and PS8PS2, PS4, PS6, and PS8. For full redundancy, these feeds must:
•
Have independent circuit breakers
•
Come from different sources
Circuit breakers should be rated based on maximum load at minimum voltage with one failed feed.
The circuit breakers shall not be rated for more than 60 A under any circumstance.
Each DC power input includes an EMI filter to reduce line-conducted emissions.
