Hi Gunthar,

Sorry to be the bearer of bad news, but the only way to upgrade the 
4000/200 to a 4000/705a is to replace the backplane in the chassis. The 
4000/300 and above only run in the BA430 chassis (whereas the 4000/200 
could run in the BA213 and BA215)

Sometimes a /300 has the faster backplane, all /400's and above do.
