Juniper EX4300 Series User Manual

This topic applies to hardware devices in the EX Series product family, which includes switches and the
XRE200 External Roung Engine, that support the LCD panel interface.
The LCD panel on the front panel of EX Series switches displays a variety of informaon about the
switch in the Status menu and provides the Maintenance menu to enable you to perform basic
operaons such as inial setup and reboot. You can disable these menus or individual menu opons if
you do not want switch users to use them. You can also set a custom message that will be displayed on
the panel.
Disabling or Enabling Menus and Menu Opons on the LCD Panel
By default, the Maintenance menu, the Status menu, and the opons in those menus in the LCD panel
are enabled. Users can congure and troubleshoot the switch by using the Maintenance menu and view
certain details about the switch by using the Status menu.
If you do not want users to be able to use those menus or some of the menu opons, you can disable
the menus or individual menu opons. You can reenable the menus or menu opons.
Issue the show chassis lcd menu operaonal mode command to see the menus or menu opons that are
currently enabled.
NOTE: On some plaorms, you must specify an FPC slot number in these commands. See the
lcd-menu statement for details.
