LCD Panel in EX4200 Switches
The LCD panel on the front panel of the switch shows two lines of text, each of which
can contain a maximum of 16 characters. The LCD panel displays a variety of information
about the switch and also provides a menu to perform basic operations such as initial
setup and reboot.
There are two navigation buttons—Menu and Enter—to the right of the LCD panel.
