5.2.2 Ethernet Connectors (GENET1/J41B, GENET2/J2B, ENET1/J2A)
There is one 10/100 and two 10/100/1000Mb/s full duplex Ethernet interfaces using the
MPC8540 Fast Ethernet Controller (FEC) and two Triple Speed Ethernet Controllers (TSEC). One
Gigabit Ethernet interface is routed to a front-panel RJ-45 connector with integrated LEDs for
speed and activity indication. The other Gigabit Ethernet interface and the 10/100 interface
are routed to P2 for rear I/O. The pin assignments for these connectors are as follows:
5.2.3 PCI Mezzanine Card (PMC) Connectors (J11 — J14, J21 — J23)
There are seven 64-pin SMT connectors on the MVME3100 to provide 32/64-bit PCI interfaces
and P2 I/O for one optional add-on PMC.
PMC slot connector J14 contains the signals that go to VME P2 I/O rows A, C, D, and Z.
The pin assignments for these connectors are as follows.
