System board and components
Note on TPM
I
The system board can be equipped with an optional TPM. This module
enables third party programs to store key information (e. g. drive
encryption using Windows Bitlocker Drive Encryption).
If the customer is using TPM functionality, the TPM has to be removed
from the defective system board and connected to the new system
board. For more information, see section
page 377.
The TPM has to be enabled in the system BIOS.
V
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 all
recovery keys which belong to the system to restore them in the TPM
later.
Note on system information backup/restore
The front panel (front panel module, front panel board or front panel on QRL)
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.
V
CAUTION!
For that reason the front panel and system board must not be replaced
simultaneously! In this case, restoring the system configuration data on
the system board would fail.
After replacing the system board the backup data is restored from the Chassis
ID board to the new system board.
