Configuration Module

Configuration Module
The configuration module is a "key" that enables activation of the full
complement of slots in the jukebox.
The module is plugged into a connector on the interposer PCA (see #1 on
Figure 5-14).
All jukeboxes are shipped with a full complement of slots installed. The
jukebox may however be sold and used as a "half" version using 32 slots.
When a configuration module is plugged into the interposer PCA, and
power is turned on, the jukebox will sense the additional 32 slots and
automatically begin operating as a full, 64-slot jukebox.
This presence of this module is confirmed regularly by the jukebox
firmware. If the module is removed, the jukebox will fail. When
restarted, the jukebox will once again operate in the "half" mode.
