SSEMBLY
The EPMs-PS1 uses PC/104 (ISA) and SUMIT AB bottom (PCI Express) connectors for
expansion. The following stacking rules apply to the EPMs-PS1:
The EPMs-PS1 must be the top SUMIT board.
The EPMs-PS1 must be stacked above the CPU board. This is a general requirement for
SUMIT expansion boards.
ISA boards can be stacked above or below the EPMs-PS1, but no ISA boards can be
stacked between the EPMs-PS1 and other SUMIT boards.
The entire assembly can sit on a table top or be secured to a base plate. When bolting the unit
down, make sure to secure all four standoffs to the mounting surface to prevent circuit board
flexing. Standoffs are secured to the top circuit board using four pan head screws. Standoffs and
screws are available as part number VL-HDW-105. Note that the standoffs in this kit are 15.25
mm (0.60 inch), and must not be mixed with the 15.0 mm standoffs used for non-SUMIT boards.
An extractor tool is available (part number VL-HDW-20
3
) to separate the PC/104 modules from
the stack. Use caution when using the extractor tool not to damage any board components.
