B.19 Power Cabinet - Fujitsu SPARC Enterprise M8000 Service Manual

B.19 Power Cabinet
A dual power feeder (DPF) and a three-phase AC power feeder are mounted on the power
cabinet. All of these are optional.
The dual power feeder receives its power supply from two independent external power
sources, ensuring that, even if a failure occurs in one source, power is supplied to the system
from the other source that in normal state. It supports both single-phase and three-phase AC.
The three-phase AC power feeder is required when the input power is three-phase AC.
