EXP-BP2 Subplane
This subplane is used in the smallest
configuration, where only the EPC-5A
processor module occupies VME slot
space. It provides connectivity for two
EXM modules within the EPC-5A (e.g.,
a graphics controller and a network or
disk controller). The EXP-BP2 is an
L-shaped board with three connectors
on each side.
After jumpering the backplane, plug the
subplane into the VMEbus backplane
such that the P2 connector on the back
of the 4-row DIN is pressed into the J2
connector of the left-most VMEbus slot
that the EPC-5A subsystem will occupy.
The subplane has holes for optional
bolting to the VMEbus backplane using
the screws included.
The lower EXM connector is denoted as
EXM slot 0 and the upper as slot 1 as
shown in the diagram. This information
will be needed later when configuring the
installed EXMs.
