Table 44. AF 100 Interface, CI869 - Indications and Fault Finding
Indication Possible Cause and Corrective Action (for faults)
Both R(un) and F(ault)
LED's are OFF
Possible Cause 1: The CI869 module is connected
to the controller, but the configuration is not
downloaded to the controller for that position.
Corrective Action 1: Ensure that the CI869 module
is configured in the Hardware Tree (in the Control
Builder) for that position, and that the configuration is
downloaded to controller.
Possible Cause 2: The CI869 module is just
powered up or it is being configured and
downloaded.
Corrective Action 2: Allow time for the module to
initialize.
Corrective Action 3: If the indication persists after
performing the corrective actions 1 and 2, then one
of the following corrective actions is recommended:
• Remove and insert the CI869 module to the
CEX-Bus and allow time for it to initialize.
• If this CI869 is the only module on the 
CEX-Bus, or if the CEX-Bus already contains
other communication modules and all the LED's
on those modules are OFF, then one of the
following corrective actions is recommended:
- Initiate a reset signal (INIT) from the PM8xx
processor unit.
- Check the CEX-Bus fuse inside the PM8xx
processor Unit
Corrective Action 4: If the indication still persists
after performing the corrective actions 1 to 3, replace
the CI869 module.
