Primary (Front) Side CPU Connectors

The CPU connectors on the CPX8216T H.110 backplane use the same pinouts as the CPX8216 standard backplane.

Primary (Front) Side HSC Connectors

The HSC/Bridge slot is unique. All five connectors (P5 through P1) use standard tails, and none of the connectors pass through to the rear.

POS	Row Z	Row A	Row B	Row C	Row D	Row E	Row F
25	GND	_AD36	_AD35	_AD34	_AD33	_AD32	GND

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).
