5.
Close the front cover of the H-CPU.
6.
Repeat steps 1 to 5 for the second H-CPU.

Uninstalling a synchronization submodule
To uninstall the synchronization modules, follow these steps:
1.
Press down lightly on the connector release and hold while pulling the connector out of
the synchronization module.
2.
Flip the synchronization module clip to the right.
3.
Pull the synchronization module out of the H-Sync interface on the CPU.
4.
Place the blanking plug on the synchronization module.
5.
Repeat the process for all H-Sync interfaces on the H-CPUs.
Protecting LC sockets on unused synchronization modules
You need to protect the LC sockets when storing unused synchronization modules.
Close off the LC sockets with the blanking plugs to protect them from dirt. The
synchronization modules come with blanking plugs inserted.
NOTICE
Reduced optical performance due to dirt
Even a small amount of dirt in the LC socket can affect the quality of the signal
transmission. Dirt can lead to synchronization losses in operation.
Protect the LC sockets from dirt when storing and installing the synchronization modules.
