Schematics of the EVM and the Interface Card

Because the interface card was originally designed for universal application
purposes, some of the components shown in the schematic above may not be
on the board when shipped with this EVM kit. Refer to the bill of materials table
for a complete component list.

A key is installed in the edge connector on the interface board (SLVP155) to
ensure that the hot-swap board can only be inserted the right direction.
