Figure 2-17: KSU Option Module Installation
Standard MOH/BGM Module
The Standard MOH/BGM Module is shipped installed in the KSU. In the event that the
Option Module was installed and the Standard MOH/BGM Module is to be re-installed,
follow these steps:
1. Make sure KSU power is OFF, and the cover is removed.
2. Connect grounded wrist strap to a suitable earth ground.
3. Locate the four screws used to secure the Option Module to the Option Module
stand-off posts. Remove each screw carefully to assure that no damage to the Option
Module results when the last screw is removed. Retain these screws.
4. Lift the Option Module away form the CPU Module, and unplug the Option Module
ribbon cable from the Option Module connector (JP1) of the CPU Module.
5. Locate the four Option Module stand-off posts. Remove the upper-right stand-off
post and replace it with the Standard MOH/BGM Module stand-off.
6. Remove each of the other stand-off posts one at a time and replace with the screws
removed in Step 3.
7. Carefully push the Standard MOH/BGM Module connector onto the MOH/BGM
connector (JP5) on the CPU Module.
8. Use one of the screws removed in Step 3 to secure the Standard MOH/BGM Module in
place.
9. Replace KSU cover and secure with cover screws, and restore KSU power. Or continue
with the installation process.
