Example for AU redundancy with SCA-RS with application-related voting:
Global redundancy switchover: all SEs of an AU are switched active/passive.
Line-by-line redundancy switchover: the SEs of an AU are switched active/passive selectively.
The FUD runs for instance on both C-CPUs of the two AUs. The synchronization mode is
High
Speed Link (HSL)
, if CAEx
plus
is used on both redundancy BSEs.

Overview of Synchronization Modes
Please note, that the representations are merely examples.
The 3 modes defined apply both for CPU as well as AU redundancy.
