Installation Cabling and Power Up IMPORTANT When running the server with a single power source, you must use A0 and A1. Selecting redundant power requires all four power cords connected to A0-A1-B0-B1. Figure 2-23 AC Power Input Labeling B1 A1 B0 A0 The power distribution for the bulk power supplies (BPS) 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 56 Chapter 2
