Preliminary Steps - Fujitsu PRIMERGY TX2550 M4 Upgrade And Maintenance Manual

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.
Note on network settings recovery
I
When replacing the system board, network configuration settings in the
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.
