Front panel and external connectors
13.1 Front panel module
13.1.1 Replacing the front panel module
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.
