Primary (Front) Side I/O Connectors
The tables in the next few sections provide pin assignments for all I/O,
HSC and CPU slots. For further connector pinouts, refer to the table below.
Primary (Front) Side (Slots 1-6 and 11-16)
The I/O connectors for slots 1-6 and 11-16, except for the P4 connector,
which carries the H.110 bus, use the same pinouts as the standard
CPX8216 backplane.

NP=Not Populated. P4 implements the full H.110 Bus connections, which requires P4 to use
depopulated connectors.
CT_RST1# through CT_RST6# are routed radially to the bridge slots.
CT_EN1# is connected to BD_SEL1# on the backplane, and so forth.
[n]=n is the slot number.
Refer to the H.110 specifications for line terminations.
