I have never figured out how to do this for an eqnarray environment - only in a regular equation. One possibility would be to use a minipage and frame it. This doesn't look to great, however...Well... better than nothing! Unfortunately the box is far larger than the equation. This is somehow different from the appearance of \boxed.
There are examples about boxed formulas in sec.9 of LyX's Math manual that you find in the Help menu. regards Uwe
