Procedure for Duplication Interface
—
Processing Element Communication
Down
In a High or Critical Reliability system, it is possible for both SPEs to stop
communicating with the A-carrier TN772 Duplication Interface (DUPINT-A) circuit
pack. Thus, the DUPINT-A, which is in charge of maintenance, prints the following
message on the administration terminal:
Duplication Interface-Processing Element Communication down
The system may continue to function on one of the SPEs. However, the system is
not able to provide any interface to the administration terminal.
If the system is still providing service, connect the administration terminal to the
Active SPE (check the amber LED on the Processor circuit pack). Then, if
software provides a login on the administration terminal, you can determine the
problems via the display alarms command.
If the system is not providing service, there is a problem with the Processor circuit
packs and/or DUPINT-A. Replace these circuit packs, one by one, until the
system starts functioning normally.
