2. Remove the following reusable components:
Caution – During the motherboard removal procedure, it is important to label the
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 same slots
from which they were removed; otherwise, the server 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 warranty on the server has not expired. For more information on the
server FRU TLI, see “FRU TLI Auto-Update” on page 30.
a. Fan modules
