LCD Panel in an EX8200 Switch

The LCD panel on the top front of the EX8200 switch chassis shows two lines of text with a maximum of 16 characters in each line. The LCD panel displays a variety of information about the switch and provides menu options to perform basic operations such as initial configuration and switch reboot.

There are two navigation buttons—Menu and Enter—to the right of the LCD panel.

See Figure 1.

Figure 1: LCD Panel in an EX8200 Switch

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 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 the idle mode, line two of the Idle menu displays the Status LED modes of the network ports and the total number of alarms in the system. The number of alarms is updated every second.

The status mode allows you to get status information for the following items:

Switch fabric in Switch Fabric and Routing Engine (SRE) modules in EX8208 switches
Routing Engine (RE) and switch fabric in Switch Fabric (SF) module(s) in EX8216 switches
Power supplies
Fan tray(s) and chassis temperature
Junos OS version installed

The maintenance mode allows you to cycle through options for configuring and troubleshooting the switch:

System halt
Reboot system
Load rescue configuration
Revert to factory configuration
EZSetup

LCD Panel Menus

The LCD panel has three menus: Idle, Status, and Maintenance. In each of these menus, line one of the LCD panel displays the hostname of the switch. Toggle between the LCD menus by pressing the Menu button. Navigate through the menu options by pressing the Enter button.

Table 1 describes the LCD panel menu options.
