RX1330 M3 Upgrade and Maintenance Manual 303
System board and components
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
I The front panel 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 and system board must not be replaced
simultaneously! In this case, restoring the system configuration data on
the system board would fail.
Note on network settings recovery
I When replacing network controllers or the system board, network
configuration settings in the operating system will be lost and replaced
by default values. This applies to all static IP address and LAN teaming
configurations.
Ensure to note down your current network settings before replacing a
network controller or the system board.
