5.2.2 Verifying system information backup/restore
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.
In order to verify whether the backup or restore process has been successful,
check the System Event Log (SEL) using the ServerView Operations Manager
(see also section "Viewing and clearing the System Event Log (SEL)" on
page 86).
