cRIO unused Modules

On the cRio, is it okay to remove unused cRIO modules? Additionally, We want to use only the alternate digital io slot six knowing slot four is the default and programing is going to have to change the program to recognize slot six. Is this okay too??

Please see Update #8. Only the 9201 (slot one) is explicitly required, but <R58> implies that a 9403 must be in slot 4. Other than that, none required.

Please note that with your cRIO should have been a bag with spare DB-15 covers. These are provided to protect unused DB-15 connectors from debris. If you do remove a module, you will probably want to install the cover.
