Installing the Expansion Module
Warning: Installing and removing the expansion module can expose dangerous voltages that
can cause electric shock resulting in injury or death. Disconnect all power before
installing or removing the option card. Dangerous voltages may be present in the
expansion module and in the unit even when the power is disconnected.
To install the optional Expansion Module:
1. Set the unit up on a clean, safe, stable work surface that provides good visibility and maneuverabil-
ity to work with screwdriver.
2. On the back panel, select an option bay and unscrew the retaining screws and remove the small
aluminum panel from the bay.
3. Line up the edges of the module with the guide grooves in the option bay and slide it in.
4. When the card is in almost all the way, push it firmly the rest of the way in until the faceplate of the
option card is flush with the back panel.
5. Insert and tighten the retaining screws so the expansion module is secured in place.
To remove the expansion module, remove the screws, pull the card out, and secure the small aluminum
panel in its place with the screws.
Configuring the Expansion Module
Each of the Expansion Module’s outputs can be independently configured to generate a signal type. This
is done using jumpers and switches located on the module. Symmetricom configures the output signals
