Configure the Redundancy Modules Chapter 6
Synchronization Status Tab The Synchronization Status tab provides a module-level view of these items:
• Synchronization state (for example, Synchronized or Disqualified)
• Chassis designation (Primary or Secondary)
• Module compatibility with its partner (for example, Full or Undefined)
Each module installed in the chassis is identified and information regarding its
partner and compatibility are provided.
Module Qual Request Synchronization was aborted because another synchronization request was received. The current synchronization has stopped so that
the new synchronization request can be serviced.
SYS_FAIL_L Deasserted Synchronization was aborted because one of the modules came out of a faulted or failed state.
Disqualify Command Synchronization was aborted because the redundancy module received a disqualify command from another device. The originating
device sends this command when it is no longer capable of performing in the qualified state.
Disqualify Request Synchronization was aborted because the redundancy module received a disqualify command from another device. The originating

Platform Configuration Identity Mismatch
Detected
There are modules in the primary or secondary chassis that do not belong to the enhanced platform.
Application Requires Enhanced Platform A redundant controller is running an application that contains a feature qualified to run only on an enhanced redundant platform, for
example, Alarms.
ICPT Asserted A test line on the backplane is asserted.
Unicast Not Supported A unicast connection is configured in the redundant controller, and enhanced redundancy systems do not support Unicast.
PTP Configuration Error A redundant controller's PTP clock is not synchronized or the partner controller pair is synchronized to a different grandmaster.
Secured Module Mismatch A mismatch was detected between a primary and secondary secured module.
