System Installation hp rp8400 Server Series AC Input Power See Figure 5-2 for the graphical representation of how the input power cords supply power to each BPS. Figure 5-2 Distribution of Input Power for Each Bulk Power Supply CAUTION Do not route data and power cables together in the same cable management arm. Do not route data and power cables in parallel paths in close proximity to each other. The suggested minimum distance that the data and power cables should be apart is 3 inches (7.62 centimeters). The power cord has current flowing through it, which creates a magnetic field. The potential to induce electromagnetic interference in the data cables exist thereby causing data corruption. There can be a total of six Bulk Power Supplies (BPS) installed in the server. • A minimum of two BPS are required to bring up a single cell board installed in the server. • N+1 capability is provided in the server when the number of BPS installed exceeds the number of cell boards installed by one BPS. • An additional BPS is required for each additional cell board installed in the server. For the case where two cell boards are installed, there would be a total of four BPS needed to support the two cell board configuration while providing N+1 functionality. NOTE Label the AC power cords during the installation. One suggestion is to use tie wraps that have the flag molded into the tie wrap. The flag can be labeled using the appropriate two characters to represent the particular AC power input (e.g. A0). Another suggestion would be to use color coded plastic bands. One color to represent the first pair A0/A1 and another color to represent the second pair B0/B1 (provided a second power source is available at the customer site). 62 Chapter 5

Distribution of Input Power for Each Bulk Power Supply
CAUTION
Do not route data and power cables together in the same cable management arm.
Do not route data and power cables in parallel paths in close proximity to each other. The
suggested minimum distance that the data and power cables should be apart is 3 inches (7.62
centimeters).
The power cord has current flowing through it, which creates a magnetic field. The potential to
induce electromagnetic interference in the data cables exist thereby causing data corruption.
There can be a total of six Bulk Power Supplies (BPS) installed in the server.
A minimum of two BPS are required to bring up a single cell board installed in the server.
N+1 capability is provided in the server when the number of BPS installed exceeds the number of cell
boards installed by one BPS.
An additional BPS is required for each additional cell board installed in the server. For the case where two
cell boards are installed, there would be a total of four BPS needed to support the two cell board
configuration while providing N+1 functionality.
NOTE
Label the AC power cords during the installation. One suggestion is to use tie wraps that have
the flag molded into the tie wrap. The flag can be labeled using the appropriate two characters
to represent the particular AC power input (e.g. A0). Another suggestion would be to use color
coded plastic bands. One color to represent the first pair A0/A1 and another color to represent
the second pair B0/B1 (provided a second power source is available at the customer site).
