hp rp8400 Server Series AC Input Power
The server can receive AC input from two different AC power sources. If two separate power sources are
available, the server can be plugged into the separate power sources increasing system reliability should one
power source fail. The main power source is defined to be A0 and A1. The redundant power source is defined
to be B0 and B1. See Figure 5-1 for the AC power input label scheme.
NOTE
When it is desired to run the server with a single power source, either A0 and A1 or B0 and B1
should be used. All other combinations are not supported. Either combination requires two
power cords.

AC Power Input Labeling
The power distribution for the Bulk Power Supplies is provided as follows:
•
A0 input provides power to BPS 0, BPS 1, and BPS 2
•
A1 input provides power to BPS 3, BPS 4, and BPS 5
•
B0 input provides power to BPS 0, BPS 1, and BPS 2
•
B1 input provides power to BPS 3, BPS 4, and BPS 5
