Caution -
During the motherboard removal procedure, it is important to label power supplies
with the slot numbers from which they were removed (PS0, PS1). This is required because the
power supplies must be reinstalled into the slots from which they were removed; otherwise, the
server key identity properties (KIP) data might be lost. When a server requires service, the KIP
is used by Oracle to verify that the warranty on the server is not expired. For more information
on KIP, see “Key Identity Properties (KIP) Automated Update” on page 51 .
