Functionality for rows A and C and Z (Z1, 3, 5, 7, 9, 11, 13, 15, and 17) is provided by the IPMC761 in slot 1 and the MVME5500 Ethernet port 2.

5.2.12Memory Expansion Connector (P4)

One 140-pin connector is used to provide memory expansion capability. This connector interfaces to up to two additional banks of memory. The pin assignments for this connector are as follows:

If a PMC module is plugged into PMC slot 1, the memory mezzanine card cannot be used because the PMC module covers the memory mezzanine connector.
