Ethernet Connectors (J2)
Dual RJ-45 connectors are located on the front panel of the MVME5500
to provide the interface to the 10/100/1000BaseTX Ethernet ports. The pin
assignments for these connectors are as follows:
IPMC Connector (J3)
One 40-pin Molex .635 mm (.025") pitch board-to-board receptacle
(52885) is used to provide a planar interface to IPMC module signals. This
receptacle mates with the Molex 53627 plug thus providing the 10.0 mm
stacking height of the PMC card. The pin assignments for this connector
are as follows:
