1. At first step we tried to put the new SW's CX110 on the 2x and 3x position but the error keeps showing.
2. Then we try to put the old SW's CX310 on the 2x and 3x and the problem was solved.
3. Then we try to put the new SW's CX110 on the 1E and 4E position keeping the old SW's CX310 on the 2x and 3x position, and the problem was not shown either. So we keep this configuration.
