Note on system information backup/restore
The common operation 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.
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 configurations with Optane PMem modules (displayed as NVM/
LRDIMM)
After replacing the system board, it is necessary to set the memory
operation mode in the BIOS in the same way as before. Ensure to note
down your current BIOS settings before replacing the system board.
