Connecting AC Input Power
The server can receive AC input from two different AC power sources. If two separate power sources are
available, each source can be plugged into the server, increasing system reliability if one power source fails.
The main power source is defined to be A0 and A1. The redundant power source is defined to be B0 and B1.
See Figure 2-23 for the AC power input label scheme.
