454 Upgrade and Maintenance Manual RX2540 M2
Front panel and external front connectors
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.
