Nozori double expansion board

2 DIP switch groups to change functions on 2 Nozori modules

2U expansion boards are available to expose the Nozori's jumpers in order to facilitate module switching. The expansion board moves the function jumpers from inside the rack to the front panel, where they can be controlled by DIP switches. You only need to change the switch positions according to the module number. If you own frontplate overlays, the switch positions are marked on their top left.
