Diagnostics of the synchronization module
You can display the following channel-specific diagnostic data in the Module state tab dialog
for the selected synchronization module:
● Overtemperature
The synchronization module is too hot.
● Fiber-optic error
The sender of the electro-optical component has reached the end of its service life.
● Violation of lower limit
The sent or received optical performance is low or too low.
● Violation of upper limit
The sent or received optical performance is high or too high.
● Functional error of the network component
The quality of the redundancy link between the CPUs (transmission distance including
synchronization modules and fiber-optic cables) is reduced so that transmission errors
are occurring frequently.
Fiber-optic interfaces of unused modules
Fiber-optic interfaces of unused modules must be blanked off during storage to protect the
optical equipment. The plugs are in the synchronization module when shipped.
Wiring and inserting the synchronization module
1. Remove the dummy plug of the synchronization module.
2. Fold back the clip completely against the synchronization module.
3. Insert the synchronization module into the IF1 interface of the first fault-tolerant CPU until
it snaps into place.
4. Insert the end of the fiber-optic cable into the synchronization module until it snaps into
place.
