32 Press and release the MAN RST button on the CP card in the new card

NORM/MAINT switch to NORM. Within 60 seconds, the LCD will

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.
33 Set the NORM/MAINT switch to NORM on the CP card in the active
Core and perform a redundancy sanity test:
