Front panel
13.2 Front panel module (2.5-inch version)
13.2.1 Replacing the front panel module
Note on system information backup/restore
The front panel (front panel module, front panel board or front panel on QRL)
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.
V
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.
When replacing the front panel, the system information like server name and
model, housing type, serial number and manufacturing data are not restored
automatically. So never forget to restore it manually by Chassis ID Prom Tool.
