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.

Two power trays occupy the bottom of the ZT 5085 platform. Each tray has its own backplane that
provides slots for four power supplies. The trays are modular for ease of replacement (the trays are
not hot swappable).
