LCD Panel in EX4500 Switches

The LCD panel on the front panel of EX4500 switch shows two lines of text, each that 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.

See Figure 1.

The first line of the text on the LCD panel displays the slot number, the role of the switch, and the hostname. For EX4500 switches, the slot number is always 00 and the role is always RE.

You can configure the second line of the LCD panel to display a custom message. If the LCD panel is configured to display a custom message, the Menu button and the Enter button are disabled. See Configuring the LCD Panel on EX Series Switches (CLI Procedure).

The LCD panel has a backlight. If the LCD panel remains idle for 60 seconds, the backlight turns off. You can turn on the backlight by pressing the Menu or Enter button once. After turning on the backlight, you can toggle between the LCD panel menus by pressing the Menu button and navigate through the menu options by pressing the Enter button.

Note: The chassis viewer in the J-Web interface also displays the LCD panel. From the J-Web interface, you can view real-time status information in the LCD panel. See Dashboard for EX Series Switches.

In the status mode, the second line displays:

  • Status of the power supplies
  • Status of the fans in the fan tray and the chassis temperature
  • Version of Junos OS for EX Series switches loaded on the switch

In the maintenance mode, the second line displays one of the following options that you can use to configure and troubleshoot the switch:

  • System halt

  • EZSetup

LCD Panel Menus

The LCD panel has three menus: Idle, Status, and Maintenance. You can toggle between the LCD panel menus by pressing the Menu button and navigate through the menu options by pressing the Enter button.
