Replacing the midplane kit

Note on system information
The chassis interface board in the midplane kit contains the Chassis ID
EPROM that contains system information like the server name, server
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.
