Upgrading Core 1

1 Set the ENB/DIS switch to ENB on the CNI card in Core/Net 1.
2 Set the ENB/DIS switch to ENB on the IOP/CMDU card in Core/Net 1.
3 On the CP card in Core/Net 1, press and release the MAN RST button.
When SYS700 messages appear on the LCD display, set the
NORM/MAINT switch to NORM. Within 60 seconds, the LCD will
display the following messages, confirming the process:

Within 10 minutes, an HWI533 message from the CPSI (Core 0) or SDI
port indicates the Core 0 memory is shadowed to the Core 1 memory.
Wait until the memory synchronization is complete before continuing.
Note 1: At this point, Core 0 is still active and in maintenance mode.
Core 1 is the standby (inactive) side. The memories are shadowed
(synchronized), but the hard disks are not synchronized (redundancy is
disabled).
4 Set the NORM/MAINT switch to NORM on the CP card in Core/Net 0
and perform a redundancy sanity test:
