Synchronizer Module
Installing a New Module
If you have ordered an audio synchronizer module (X75OPT-AS-8,
X75OPT-AS-8-L, X75OPT-AS-16, or X75OPT-AS-16-L) separately to
upgrade your system, follow these installation steps:
1. Remove the chassis cover (see “Preparing the X75HD/X75SD for
Servicing” on page 261).
2. Remove the screws from the blank filler plate on the rear panel
where the new audio synchronizer module is to be installed, and
then remove the plate.
Retain the screws for later use.
3. Remove the packaging from the audio synchronizer module.
The package includes one board, four stackers, and the required
number of standoff screws.
4. Turn the module upside down and insert the four stackers into the
corresponding connectors on the underside of the board.
See Figure C-4.
