Stratum 3 Clock Module
To replace the clock module in the CX/CXi, or MXe:
1. Remove the screws from the clock module.
2. Remove the clock module.
3. Seat the new clock module onto the main board.
4. Replace the screws that you removed from the clock module.
Note: The other controllers use the Stratum 3 Clock, but in each case, the
clock is embedded and is not field replaceable. The MXe Server does not
use a Stratum 3 Clock.
