Move Heart to new CPU card
Take the CPU card being replaced and remove the SD card from the slot marked
"HEART". Insert this SD card into the replacement CPU card. To insert a card, align
it with the socket with the contacts facing PCB and closest to the socket, slide it into
the socket and apply slight pressure until it 'clicks'. The card is now located
correctly. The photos below show the correct orientation for the card.
Note: It is important that the card is not write protected. The 'lock' switch must be in
the position shown in the diagram below:

When restoration from Heart is being performed to clone a system
onto a replacement CPU card then it is important that the Ethernet
cable (if used) is not connected to the replacement CPU card until the
restore from Heart operation is complete. This is because if the
replacement CPU card has been previously used it might have
network configuration remaining within it which conflicts with the
network being connected to.
