Table 6-33. P5 Connector, HSC/Bridge (Slots 8 and 10) (continued)
POS Row Z Row A Row B Row C Row D Row E Row F
The _GND, _+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 10 or CPUB if the board resides in slot 8 (for example, CPUA_+5).
Unshaded signals beginning with an underscore (_) are prefixed with the local PCI bus name:
*For boards located in slot 10 (Domain A), the signal name is prefixed with L_PCI_A (for
example, L_PCI_A_AD17).
*For boards located in slot 8 (Domain B), the signal name is prefixed with L_PCI_B (for example,
L_PCI_B_AD17).
