Remote Reset Connector - J2
The MVME172LX has a 20-pin connector (J2) mounted behind the front
panel. When the MVME172LX board is enclosed in a chassis and the front
panel is not visible, this connector enables you to extend the reset, abort
and LED functions to the control panel of the system, where they remain
accessible.
IndustryPack A and B Connectors - J4/5/6, J3/7/8
Up to two IndustryPack (IP) modules may be installed on the
MVME172LX. For each IP module, there are two 50-pin plug connectors
on the board: J5/6 for module A, J7/8 for module B. For external cabling
to the IP modules, two 50-pin IDC connectors (J4 for module A, J3 for
module B) are provided behind the MVME172LX front panel. The pin
assignments are the same for both types of connector.
