LCD Panel in EX3200 and EX4200 Switches

The LCD panel on the front panel of EX3200 and EX4200 switches shows two lines of text, each a maximum of 16 characters in length. 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.

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 is 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.

LCD Panel Modes

The LCD panel operates in four modes: boot, idle, status, and maintenance.

The LCD panel operates in boot mode during switch reboot. The boot mode displays the key milestones in the switch boot process. The boot mode does not have any menu options. After the boot process is complete, the LCD panel automatically reverts to the Idle menu.

In an EX3200 switch, the first line of the LCD panel displays the hostname.

In an EX4200 switch that is not a member of a Virtual Chassis, the first line of the LCD panel displays the slot number, the role of the switch, and hostname. For a standalone EX4200 switch, the slot number is always 00 and the role is always RE (for master).

In an EX4200 switch that is a member of a Virtual Chassis, the first line of the LCD panel displays:

  • The slot number (the member ID for the Virtual Chassis member)
  • Role of the switch in a Virtual Chassis (RE for master, BK for backup, and LC for linecard member)
  • Hostname

In the idle mode, the second line displays the mode of the network ports’ Status LED and the number of chassis alarms. The number of alarms is updated every second.

In the status mode, the second line displays:

  • Virtual Chassis port (VCP) status (for an EX4200 switch that is a member of a Virtual Chassis)
  • Status of the power supply
  • Status of the fan and temperature
  • Version of JUNOS Software 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
  • System reboot
  • Load rescue
  • Request VC port (for an EX4200 switch that is a member of a Virtual Chassis)
  • Factory default
  • System EZSetup

LCD Panel Menus

The LCD panel has three menus: Idle, Status, and Maintenance. Toggle between the LCD panel menus by pressing the Menu button. Navigate through the menu options by pressing the Enter button.
