Installing the Controller Module
Note
When a new controller module is installed, the resident controller checks the
firmware version of the new controller. If the versions do not match, the
resident controller downloads its firmware to the new controller module. This
procedure, called Auto Code Synchronization (ACS), ensures that both
controllers are operating with the same version of firmware. See "Auto Code
Synchronization (ACS)" on page 204 for more information.
