After you set the DIP switches on a media bay module, you can install it in the BCM or an expansion unit - all bay slots are the same.

When adding a module, remember to tell the system what type of module is installed on each bus:

If a module status LED continues to flash, you have either an addressing conflict (check DIP switches), or a faulty module.

Remember, the BCM must be shut down before inserting or removing modules.
