CAUTION!
– Before replacing the system board, ask the customer whether TPM
functionality is used.
– If the customer is using TPM functionality, remove the TPM from the
old system board and install it on the new system board.
Advise your contact persons that they must provide you with TPM
backup copies. For security reasons, the TPM must be restored / re-
saved by the customer. After installing a new system board the TPM
must be enabled. You may not clear the TPM data.
If the contact persons DO NOT have a backup copy available, inform
them that replacing the TPM board will cause to lose all data.
Note on system information backup / restore
I
The front panel module contains the Chassis ID EPROM that contains
system information like server name and model, housing type, serial
number and manufacturing data.
To avoid the loss of non-default settings when replacing the system
board, a backup copy of important system configuration data is
automatically stored from the system board NVRAM to the Chassis ID
EPROM. After replacing the system board the backup data is restored
from the Chassis ID board to the new system board.
V
CAUTION!
– For that reason the front panel module and system board must not be
replaced simultaneously! In this case, restoring the system
configuration data on the system board would fail.
– The system information won't be restored automatically after
replacing the faulty system board with old BIOS versions. If possible,
please note down all current BIOS settings before replacing.
