ENTERING CPU VOTE
By the active CPU, an HWI533 message from the CPSI or SDI port
indicates the memory is shadowed.
Note 1: At this point, the other Core is still active and in split mode. The
Core in the new card cage is the standby (inactive) side. The memories
are shadowed (synchronized), but the hard disks are not synchronized
(redundancy is disabled).
Note 2: A CNI port LED may not go out if a network loop
corresponding to that port is disabled.

Core and perform a redundancy sanity test:
