In Section 4 Ordering Guide, made rows for
CX870-3B, 3H, 3I, 3J shaded.
All new designs should use modules with a
bottom shield, so modules without a bottom
shield are now marked as "NOT TO BE USED
FOR NEW/STANDARD MP DESIGNS" by
shading the rows in the Ordering Guide table for
those modules with no bottom shield.
