Tue Mar 18 15:53:03 2003

The front panel will display system messages (e.g., during reboot or save events) but will return to the ‘normal’ display after these events are done.

Note

The Edit Mode can be disabled, and the front panel display’s normal display can also be changed.

The default setting allows the editing of the IP address information using the front panel buttons. This can be disabled to prevent unauthorized changes.

7.7.1 Display Mode Parameters

The various LCD Display modes are controlled by the entries maintained in the /etc/sysconfig/lsi directory for the following files:

LCD_LINE_1=

LCD_LINE_2=

LCD_DISPLAY_SETTING=

•LCD_LINE_1= and LCD_LINE_2= allows text entry of up to 24 charac- ters to be displayed.

•LCD_DISPLAY_SETTING= can be set to EDIT (default), VIEW, or OFF.

7.7.1.1 Edit

The Edit mode (LCD_DISPLAY=EDIT) allows the front panel display to normally show the current Display information, and allows anyone to use the front panel display to change the network parameters (IP Address, Net Mask, and Gateway).

7.7.1.2 View

The View mode (LCD_DISPLAY=VIEW) allows the front panel display to show the current information, but disables the editing using the front panel buttons. This prohibits unauthorized changes to your network settings from the front panel.
