Tower Elevator Connections
6.1
The TWR-P1025 features two expansion card-edge connectors that interface to the primary and secondary
elevator boards in a Tower system. The Primary Connector (comprised of sides A and B) is utilized by the
TWR-P1025 while the Secondary Connector (comprised of sides C and D) makes connections to the the
SER3 & 7 Serial ports as well as ENET5 RMII and three SERDES lanes. Table 14 provides the pinout for
the Primary Connector. Table 15 provides the pinout for the Secondary Connector.
