Caution - When reinstalling power supplies, it is important to reinstall them into the slots
from which they were removed during the motherboard removal procedure; otherwise, the server's FRU
top-level indicator (TLI) data might be lost. When a server requires service, the
FRU TLI is used by Oracle to verify that the server's warranty has
not expired. For more information on the server's FRU TLI, see the Administration, FRU TLI Auto-Update.

Note - IMPORTANT: After replacing the motherboard, you might need to manually program the product
serial number (PSN) into the new motherboard. This is necessary because the motherboard
is a secondary quorum member for maintaining the PSN for service entitlement, and if
you replace more than one of the quorum members during any given service
procedure, a secondary quorum member might need to be programmed with the PSN.
