The _+5 and _+3 in the shaded cells are provided by the CPU board; they are not connected to the
system power plane. These signals are prefixed with CPUA if the board resides in slot 7 or CPU
B if the board resides in slot 8 (for example, CPUA_+5).
Signals beginning with an underscore (_) are prefixed with the local PCI bus name:
*For boards located in slot 7 (Domain A), the signal name is prefixed with L_PCI_A (for example,
L_PCI_A_AD17).
*For boards located in slot 9 (Domain B), the signal name is prefixed with L_PCI_B (for example,
L_PCI_B_AD17).
