ATCA-7540 Installation and Use (6806871A01A) 77
Some of the pins provided by P20 and P23 are defined as optional in the AdvancedTCA
specification and are unused on the blade. If the AdvancedTCA specification defines these
signals as input signals, they are terminated on the blade and marked as “TERM_” in the
following pinouts. In all other cases the pins are unconnected and consequently marked as
"n.c."
The pinouts of P20, P23, P30, P31, and P32 connectors are shown below.
